Accrued Interest =
(Days since last coupon payment/Days between coupon payment) * Coupon amount
LIBOR - OIS Spread
(OIS Rate reflects the Overnight indexed swap rate which is the federal funds rate and includes minimum credit risk) LIBOR - OIS spread is a good indicator of credit risk and overall wellbeing of the banking system Low LIBOR - OIS Spread indicated high market liquidity High LIBOR - OIS Spread indicated Low Market Liquidity
Key Rate Duration
(Partial Duration) Captures the interest rate sensitivity of a bond to changes in yields (Par rates) of a specefic benchmark maturity. Key Rate duration is used to identify the interest rate risk from changes in the shape of the yield curve (Shaping risk)
Sinking Funds Bonds
(Sinkers) which require the issuer to set aside funds periodically to retire the bond (sinking fund). This provision reduces the credit risk of the bond. Sinkers typically have several related issuer options
Combinations of interest rate options can be used to replicate other contract; such as:
1) A long interest call and a short interest rate put (with X = Current FRA rate) can be used to replicate a long FRA 2) Similarly, the the exercise rate = current FRA rate, A short interest rate call and a long intrerest rate out can be combined to replicate a short FRA position 3) A series of interes rate call options with different maturities and the same exercise price can be combined to form an interest rate cap. A floating rate loan be hedged using a long interest rate cap 4) Similarly an interest rate floor is a portfolio of interest rate put options, and each of these puts is known as a flooret. floors can be used to hedge a long position in a floating rate bond 5) If the exercise rate on a cap and floor is the same, a long cap and a short floor can be used to replicate a payer swap 6) Similarly a short cap and a long floor can replicate a receiver swap 7) If the exercise rate on a floor and a cap are set equal to a market swap fixed rate, the value of the cap will equal to the value of the floor
Time conventions for calculations
1) All LIBOR based, FRA's, Swaps. Caps, Floors: 360-day convention, (r*(day/360)) 2) Equities, bonds, currencies, stock options: 365 days, (1+r)^(days/365) 3)Equity Indexes: continuously compounded, raise e^(r* Days/365)
Ways to determine NAV
1) At cost, adjusting for subsequent financing and devaluation 2) At the minimum of cost or market value 3) By revaluing the portfolio company anytime there is new financing 4)At Cost, with no adjustment until exit 5) By using a discount factor for restricted securities 6) less frequently, by applying illiquidity discounts to values based on those of comparable publicly traded companies
Components of Credit Analysis:
1) Collateral Pool: Credit analysis of structured securitized debt begins with the collateral pool. Homogeneity of a pool refers to similarity of assets within the collateral pool. Granularity refers to the transparency of assets within the pool. A highly granular pool would have hundreds of clearly defined loans, allowing for summary statistics to be used 2) Servicer Quality: is important to evaluate the ability of the servicer to manage the origination and servicing of the collateral pool. After origination, investors in secured debt face the operational and counterparty risks in a collateral pool. One Key Structural element is credit enhancement, which may be internal or external. 3) Structure: Determines the trenching or other management of credit and other risks in a collateral pool. One key structural element is credit enhancement, which may be internal or external
Factors driving the Development of electronic trading systems are:
1) Cost 2) accuracy 3)Audit trails 4) Fraud prevention 5) Continuous market
3 different approaches to valuing real estate
1) Cost approach: is that a buyer would not pay more for a property than it would cost to purchase land and construct a comparable building. Under the cost approach, value is derived by adding the value of the land to the current replacement costs of a new building, less adjustments for estimated depreciation and obsolescence: Cost approach is best used when the entity is newly constructed 2) Sales Comparison Approach: Is that a buyer would pay no more for a property than others are paying for similar properties. The sales prices of similar properties are adjusted for differences within subject property. The sales comparison approach is good when there are a number of similar properties to the subject that have recently sold 3) Income Approach: Is the value based on the expected rate of return required by a buyer to invest in the subject property. With the income approach, value is equal to the present value of the subjects future cash flows. the income approach is most useful in commercial real estate transactions
Determinants of Term structure of Credit spreads
1) Credit Quality: Is an important factor driving terms structure; AAA terms tend to be flat or slightly upward sloping. Lower-rated sectors tend to have steeper spread curves 2) Financial Conditions affect the credit spread curve. Spreads Narrow during economic Expansions and widen during cyclical downturns. During boom times, benchmark yields tend to be higher while credit spreads tend to be more narrow 3) Market Demand and supply; influence the shape of the spread curve. Recall that a credit spread includes a premium for lack of liquidity. hence, less liquid maturities would show higher spreads (Even if the expectations for that time period are stable). Due to low liquidity in most corporate issues, the credit curves are most heavily influenced by more heavily traded bonds. Because newly issued bonds are generally more liquid, when an issuer refinances a near dated bond with a longer term bond, the spread may appear to narrow for the longer maturity (possibly leading to an inverted credit spread curve) 4) Equity Market Volatility: Company value models (Structural models) employ a company's stock price volatility and balance sheet structure in determining the probabilities of default. Increases in equity volatility therefore tend to widen spreads and influence the shape of the credit spread curve
Income approach for Real Estate has 2 methods
1) Direct Capitalization method 2) DCF
Six methodologies to valuing private equity portfolio companies:
1) Discount Cash Flow method (DCF) is most appropriate for companies with a significant operating history because it requires an estimate of cash flows 2) A relative value or market approach: applies a price multiple, such as P/E, against the company's earnings to get an estimate of the company's valuation. This approach uses predictable cash flows and a significant history 3) Real option analysis 4) this approach uses Replacement Cost of the business. It is generally not applicable to mature companies whose historical value added would be hard to estimate 5) Venture capital and LBO methods
Sources of tracking error for an ETF include:
1) Fees and expense 2) Sampling and optimization 3) Depository receipts 4) Index changes 5) regulatory and tax requirements 6) Fund accounting practices 7) Asset Manager Operations
Types of exit routes for a Private Equity firm
1) IPO 2) Secondary market sale 3) MBO 4) Liquidation
Generalizations can be made about key rates:
1) If an option free bond is trading at par, the bonds maturity matched rate is the only rate that affects the bonds value 2) For an option free bond, not trading at par, the maturity matched rate is still the most important rate 3) A bond with a low or zero coupon rate may have negative key rate durations for horizons other than the bonds maturity. This is evidenced by some negative key rate durations for 1-2% coupon bonds 4) A callable bond with a low coupon rate is unlikely to be called; hence the bonds maturity matched rate is the most critical rate (i.e the highest key rate duration corresponds to the bonds maturity) 5) All else equal, higher coupon bonds are more likely to be called, and therefore the time to exercise rate will tend to dominate the time to maturity rate 6) Putable bonds with high coupon rates are unlikely to be put, and thus are more sensitive to their maturity matched rates. 7) All else equal, lower coupon bonds are more likely to be put, and therefore the time to exercise rate will tend to dominate the time to maturity rate.
3 Important things to remember about FRAs when pricing and valuing them
1) LIBOR rates in the EuroDollar Market are Add-on rates and are always quoted on a 30/360 day basis in annual terms. For example if the LIBOR quote on 30-day Loan = 6%, the actual unannualized monthly rate is 6% * (30/360) = .5% 2) The Long position in an FRA is, in effect, Long the rate and benefits when the rate increases 3) Although the interest on the underlying loan wont be paid until the end of the loan, the payoff on the FRA occurs at the Expiration of the FRA. Therefore the payoff of the FRA is the Present Value of the interest savings on the loan
VaR has three components
1) Loss Size 2) Probability of a loss that is >= Loss Size 3) Time frame
The In-Kind creation/redemption process for ETFs serves these purposes:
1) Lower cost: The creation/redemption process does not force the ETF manager to sell/purchase portfolio investments; the manager does not incur and resulting transaction costs. The manager usually collects a service charge from the AP to cover any incidentals 2) Tax efficiency: A major benefit of the In-kind creation/ redemption process is that it is not a taxable event. For a mutual fund, liquidity needs for redemption are often met by the fund manager by selling some of the funds holdings, which triggers transaction costs as well as potential cap gains tax. 3) Keeping market prices in line with NAV: APs will engage in arb if the ETF trade at a price significantly different from their NAV. If the ETF trades at a premium, APs can sell the ETF, purchase the creation basket, an recreate those shares....
Due diligence of PE fund investors
1) PE funds have returns that tend to persist. Hence a funds past performance is useful info. 2) Return discrepency between outperformers and underperformers is very large and can be as much as 20% 3) PE investments are usually illiquid, long term investments. The duration of a PE investment, however, is usually shorter than expected
Advantages of reduced form models
1) RF models do not assume that the assets of a company trade 2) Default intensity is allowed to vary as company fundamentals change, as well as when the state of the economy changes
Disadvantages of Reduced Form models
1) RF models do not explain why default occurs 2) Under RF models, default is treated as a random event, but in reality, default is rarely a surprise, and is often predicted by several credit downgrades
Subtypes of Equity REITs
1) Retail or shopping centers: Lease rates and sales per sq foot are important factors to analyze 2) Office reit: analysts must consider property location, convenience, and access to transportation, and the quality of the space including the condition of the building 3) residential REIT; Factors to consider are local demographics, availability of subs, any rent controls imposed by local governments, age of properties, impact of rising costs must be considered 4) health care reits; health care reits are usually unaffected by the economy, however government funding, demographic shifts, new construction v demand, increases in costs of insurance, and potentials for lawsuits persist. 5) Industrial REITs; usually less cyclical; new properties coming onto the market and demand for such space by tenants will affect the value of existing properties 6) Hotel REITs; like healthcare reits, they usually lease properties to management companies, so the reit receives only passive rental income 7) Storage reits; important factors to consider are local factors that drive demand for storage, such as housing sales, new business start ups, demographic trends 8) Diversified reits
Components of return for a private equity investment are
1) Return on the preference shares for PE firm 2) The increased multiple upon exit 3) reduction in the debt claim
Assumptions underlying the Black-Scholes-Merton model
1) The Underlying asset price follows a geometric Brownian motion process. the asset price therefore has a lognormal distribution. In other words, the continuously compounded return is normally distributed. Under this framework change in asset price is continuous 2) The risk free rate is constant and known. Borrowing and lending are both at the risk free rate 3) Volatility of the returns on the underlying asset is constant and known. the price of the underlying asset changes smoothly 4) Markets are 'frictionless' There are no taxes, no transaction costs, and no restrictions on short selling 5) The yield on the underlying asset is constant 6) The options are euro options
The underlying process for calibrating a Binomial Interest Rate tree
1) The interest rate tree should generate arbitrage free values for the benchmark security 2) As stated earlier, adjacent forward rates are two standard deviations apart (e^(2*st.d) 3)The middle forward rate in a period is approx equal to the implied (From the becnhmark spot curve) one period forward rate for that period
3 main inputs for a LBO model
1) The target company's forecasted cash flows 2) The expected returns to the providers of the financing 3) the total amount of financing
Two types of arbitrage Opportunities
1) Value additivity: when the value of whole differs from the sum of the values of parts 2) Dominance: When one asset trades at a lower price than another asset with identical characteristics
Issues in calculating NAV
1) if NAV is only adjusted when there are subsequent rounds of financing, then the NAV will be more stale when financings are infrequent 2) There is no definitive method for calculating NAV for a PE fund because the market value of the portfolio companies is usually not certain until exit 3) Undrawn LP capital commitments are not included in the NAV calc. but are essentially liabilities for the LP. The value of the commitments depends on the cash flows generated from them, but these are quite uncertain. When a GP has trouble raising funds, this implies that the value of these commitments are low 4) The investor should be aware that funds with different strats and maturities may use different valuation methods 5) It is usually the GP who values the fund. LPs are increasingly using 3rd parties to do the valuation
Sources of premiums or discounts for an ETF include
1) timing differences. ETF on foreign securities may experience gaps between the time the ETF is traded and the time when the underlying trades in a foreign market. 2) Stale pricing: Infrequently traded ETFs may reflect noncurrent prices and therefore, their value may differ from the NAV
Embedded Options in a bond allow an issuer to
1)Manage interest rate risk 2) issue bonds with an attractive coupon rate
3 VaR Models:
1)Parametric or variance covariance method -- uses assumption of normality 2) Historical simulation method-- based on actual periodic changes in risk factors 3)Monte Carlo Simulation: based on an assumed probability distribution for each risk factor. Additionally, and assumption must be made about the correlations between risk factors. This procedure is repeated 1000s of times.
Expected Return on a Bond will equal the bonds YTM only when...:
1)The bond is held to maturity 2)All payments are made on time and in full 3)All coupons are reinvested at the YTM

Default Intensity
A key input for Reduced Form models; it is the probability of default over the next (small) time period. Default intensity can be estimated using regression models.
Key rate duration
A more precise method to quantify bond price sensitivity to interest rates is key rate duration. Compared to effective duration, key rate duration is superior for measuring the impact of nonparallel yield curve shifts Key rate duration is the sensitivity of the value of a security (or bond port) to changes in a single par rate, holding all other spot rates constant. In other words, key rate duration isolates price sensitivity to a change in the yield at a particular maturity only Key rate duration is defined as the approximate percentage change in the value of a bond portfolio in response to a 100 basis point change in the corresponding key rate, holding all other rates constant
Fundamental factor model example
A multi factor model to evaluate style and size exposure
Excess return swap
A party may make a single payment at the initiation of the swap and then receive periodic payments of any percentage by which the commodity price exceeds some fixed or benchmark value, times the notional value of the swap. In months in which the commodity price does not exceed fixed value, no payments are made
Equivalencies of a Swaption
A receiver swap can be replicated using a Long receiver swaption and a short payer swaption with the same exercise rates. Conversely a oayer swap can be replicated using a long payer swaption and a short receiver swaption with the same exercise rates. If the exercise rate is set such that the values of the payer and receiver swaption are equal, then the exercise rate must be equal to the market swap fixed rate A long callable bond can be replicated using a Long option free bong plus a short receiver option
Under the Structural Model, Risky Debt can be thought of as equivalent to a portfolio comprising a long position in a Risk free bond and:
A short Put Option on Assets of the company, with a strike price equal to facevalue of debt
Liquidity Preference Theory of term structures
Addresses the short comings of the pure expectations theory by proposing that forward rates reflect investors expectations of future spot rates, plus a liquidity premium to compensate investors for exposure to interest rate risk. Furthermore, the theory suggests that this liquidity premium is positively related to maturity Thus the liquidity preference theory states that forward rates are biased estimates of the markets expectation of future rates because they include a liquidity premium Therefore a Positive sloping yield curve may indicate that either; 1) the market expects future interest rates to rise 2) Rates are expected to remain constant(or even fall) but the addition of the liquidity premium results in a positive slope. A down ward sloping yield curve indicates steeply falling short term interest rates according to the Liquidity Preference Theory Size of liquidity premium do not need to be constant over time
Hazard rate
Affects both the premium leg and protection leg
Extendible Bond
Allows the investor to extend the maturity of the bond, it can be evaluated as a putable bond with a longer maturity
Preferred Habitat Theory
Also proposes that forward rates represent expected future spot rates plus a premium; but it does not support the view that this premium is directly related to maturity Instead it suggests that the existence of an imbalance between the supply and demand for funds in a given maturity range will induce lenders and borrowers to shift from their preferred habitats (Maturity ranges) to one that has the opposite imbalance. However, to entice investors to do so, the investors must be offered an incentive to compensate for the exposure to price and or reinvestment rate risk in the less than preferred habitat. Borrowers require cost savings (i.e ;lower yields) and lenders require a yield premium (i.e higher yields) to move out of their preferred habitats Under this theory, premiums are related to supply and demand for funds at various maturities. Unlike the Liquidity preference theory, under the preferred habitat theory, a 10-year bond might have a higher or lower risk premium than the 25-year bond. It also means that the preferred habitat theory can be used to explain almost any yield curve shape
economic capital
Amount of capital a firm needs to hold for it to survive severe losses due to the risks in its business
Index Credit Default Swap
An Index CDS covers multiple issuers, allowing market participants to take on an exposure to the credit risk of several companies simultaneously in the same way that a stock index allows one to. The protection for each issuer is equal (Equally weighted) and the total notional principal is the sum of the protection on all the issuers
A decrease in interest rate volatility will decrease the value of:
An embedded short call on a bond (But have no effect on the value of the embedded call on the stock) and Increase the Value of the Convertible bond
Riding the Yield Curve
An investor will purchase bonds with maturities longer than investment horizon in hopes that the yield curve wont change, and they can sell the bonds for a capital gain prior to maturity
Investing in a Noncallable, Nonputable Convertible bond is the same as buying:
An option free bond and a call option on an amount of common stock that is equal to the Conversion ratio
Swaptions
An option that gives the holder the right to enter in an Interest Rate Swap Payer Swaption: Is the right to enter into a specific swap at some date in the future at a predetermined rate as the FIXED RATE PAYER Receiver Swaption: is the FLOAT PAYER As interest rates increase; the right to take the Pay-Fixed (A payer swaption) side of a swap becomes more valuable. The holder of a receiver would exercise if the market rates are less than the exercise rate at expiration A swaption is = an option on a series of cash flows (annuity), one for each settlement date of the underlying swap, equal to the difference between the exercise rate on the swap and the market swap fixed rate
Forward Rate
Annualized interest rate om a loan to be initiated at a future period
Hypothetical scenario
Any set of changes in risk factors can be used

A credit event (i.e default) will occur when
Bankruptcy occurs: A bankruptcy protection filing allows the defaulting party to work with creditors under the supervisions of the court so as to avoid full liquidation Failure to pay: Restructuring
The Cox-Ingersoll-Ross Model
Based on the idea that interest rate movements are driven by individuals choosing between consumption today versus investing and consuming at a time later
Theory of storage for Futures return
Based on the idea that whether a futures market is backwardated or in contango depends on the relationship between the costs of storing the commodity for future use and the benefits of holding the comodity inventory. When the costs of storage outweigh the benefits for holding inventory, futures are more attractive than current inventory, futures will trade at a higher price than spot, and market is in contango When the benefits of holding inventory > costs of storage, market is backwardated and spot prices are greater than futures
If default probabilities are expected to be higher (Or recovery rates Lower) in the future the credit curve would be expected to
Be positively sloped Flat credit curves indicate stable expectations over time
Arbitrage free models
Begin with the assumption that bonds trading in the market are correctly priced. These models do not try to justify the current yield curve; rather they take the curve as given The ability to calibrate arb free models to match current market prices is one advantage over equilibrium models
Commerical real estate investments have:
Bond like charactoristics: The steady rental income stream is similar to cash flows from a portfolio of obnds. Furthermore, just as the credit quality of issuers affect the value of a bond portfolio, the credit quality of tenants also affects the value of commercial real estate Equity like characteristics: The value of commercial real estate is influenced by many factors, including the state of the economy, the demand for rental properties, and property location. Uncertainty about the value of the property at the end of the lease term gives it this characteristic Illiquidity
Option Adjusted Spread rules (OAS)
Bonds with similar credit risks should have identical OAS If the OAS for a bond is higher than the OAS of its peers, bond is undervalued If the OAS for a bond is lower than the OAS of its peers, the bond is Overvalued
A synthetic Euro put option is created by:
Buying the discount bond, buying the call option, and short selling the stock
Steps for valuing an option with a Two-Period Binomial Model
Calculate the stocks value at the end of the two periods (There are three possible outcomes, because an up the down move gets the same place as a down then up move) Calculate the three possible option payoffs at the end of two periods Calculate the expected option payoff at the end of two periods using the up and down move probabilities Discount the expected option payoff (t=2) back one period at the risk free rate to find the option values at the end of the first period (t=1) Calculate the expected option value at the end of period 1 using the up and down move probabilities Discount the expected option value at the end of one period back one period at the rf rate to find the option value today (T=0)
We can calculate the value of an option on a stock by:
Calculating the payoff of the option at maturity in both the up move and down move states Calculating the expected value of the option in one year as the probability weighted average of the payoffs in each state Discounting the expected value back to today at the risk free rate
Option Value related to interest rates:
Call option value is Inversely related to the level of Interest Rates Put option value varies directly with the level of interest rates
Negative convexity occurs in
Callable bonds, due to a decline in interest rates when rates are already low, therefore a decline in rates is not likely to result in best price performance for a callable bond
When an Upward Sloping yield curve (normal) flattens, Options do what on Bonds

Valuation of an option free bond using Pathwise Valuation
Create paths for the maturity of the bond, ex: 3 years, for each year you will trace out what interest rates will be used, and then to get the value for the year, you will sum up the (coupon / 1+r) Ex: for a 3 year 3% coup on $100 par V1 = 3/1.03+3/1.03*1.05783 + 103 / 1.03* 1.057883 * 1.107383
Credit ratings incorporate both
Default probability and loss given default
Delta
Describes the relationship between changes in asset prices and changes in option prices. Delta is also the Hedge Ratio Call option deltas are Positive because as the underlying asset price increases, call options value increase. The delta of a Put option is Negative because as put value falls, asset prices increase Delta is the slope of the Prior to expiration curve
In credit rating, the practice of notching accounts for:
Differences in Loss Given Default
Common errors made using the DCF method
Discount rate does not adequately capture risk. Income growth exceeds expense growth The terminal Cap rate and the going-in cap rate are not consistent The terminal cap rate is applied to NOI that is atypical The cyclicality of real estate markets is ignored
Reduced form models of corporate credit risk
Do not rely on the structure of a company's balance sheet, and therefore, do not assume that the assets of the company trade. Unlike structural models, reduced form models do NOT explain why default occurs They explain WHEN default occurs
One-Sided Duration
Durations that apply only when interest rates rise (or only when rates fall) -- are better are capturing interest rate sensitivity than simple effective duration
Compare Effective Duration callable, putable, and straight bonds
Effective duration (Callable) <= Effective Duration (straight) Effective Duration (Putable) <= EffDur (straight) EffDur(Zero coup) = Maturity of bond (approx) EffDur of Fixed rate coup bond < Maturity of bond Effdur of Floater (approx) = Time (in years) to next reset

Implications for the Shape of the Yield Curve under the Pure Expectations Theory are:
If the Yield Curve is upward Sloping, Short Term rates are expected to rise If the curve is downward sloping, short term rates are expected to fall A flat yield curve implies that the market expects short term rates to remain constant
How options on Interest Rates work
Interest rate options are options on Forward Rate agreements (FRA's). A call on an FRA Gains when Rates Rise A put on an FRA Gains when Rates Lower Interest rates are fixed in advanced and settles in arrears (i.e paid at maturity of the loan) While usually FRA use a 30/360 convention Options on an FRA use the 30/365 convention
Examples of Credit Enhancements:
Internal Include trenching of credit risk among classes with differing seniority (i.e distribution waterfall), Overcollateralization, and excess servicing spread (whereby such excess collateral or spread becomes the first line of defense against credit losses). External Third party guarantees (e.g bank, insurance comps, loan originators) are exampled of external credit enhancements
Unbiased Expectations Theory (Pure expectations)
Investors expectations that determine the shape of the Interest Rate Term Structure; Specifically, this theory suggests that forward rates are solely a function of expected future spot rates and that every maturity strategy has the same expected return over the given investment horizon In other words, long term interest rates equal the mean of future expected short term rates This implies that an investor should earn the same return by investing in a five year bond that will be sold two years prior to maturity Investors demand a risk premium for maturity strategies that differ from their investment horizon
Implementation shortfal
Is a conceptual approach that measures transaction costs as the difference between the value of the actual portfolio and the value of a hypothetical paper portfolio. In a paper portfolio, the trade was executed at no cost and at the prevailing price.
Information Coefficient (IC)
Is a measure of a managers skill. IC is the Ex-Ante (i.e expected) risk weighted correlation between active returns and forecasted active returns. The ex post info coefficient, ICr, measures actual correlation between active returns and expected active returns
Marginal VaR MVaR
Is estimated as the slope of a curve that plots VaR as a function of a security's weight in the portfolio. The MVaR is calced at the point on the curve corresponding to the security's current weight, so we can interpret it as the change in VaR for as 1% increase in the security's weight.
Incremental VaR IVaR
Is the change in VaR from a change in the portfolio allocation to a security. If a 2% increase in the weight of a security in the portfolio increases the portfolios VaR from $1,345,600 to $1,562,400 the IVaR for the 2% increase in the portfolio weight is the difference = $216,800
Functional Obsolescence
Is the loss in value resulting from defects in design that impairs a buildings utility. For example, a building might have a bad floor plan, as a result, NOI is usually lower than otherwise would be because of the lower rent or higher operating costs. Functional obsolescence can be estimated by capitalizing the decline in NOI

Effective Duration
Measures price sensitivity to small PARALLEL shifts in the yield curve. It is important to note that effective duration is not an accurate measure of interest rate sensitivity to Non-Parallel shifts in the yield curve, Shaping risk refers to changes in portfolio value due to changes in the shape of the benchmark yield curve
Ex Ante Tracking error, or Relative VaR
Measures the VaR of the difference between the return on a portfolio and the return on its managers benchmark portfolio. A 5% monthly relative VaR of 2.5% implies that 5% of the time, the portfolios relative underperformance will be at least 2.5%. The relative VaR can be calculated as the VaR of a combination of long positions in hte subject portfolio and a short position in the benchmark portfolio.

Measures the bonds price sensitivity to changes in interest rates, assuming that the bonds cashflows do not change as interest rates change
Gama
Measures the rate of change in Delta Gamma captures the curvature of the option value versus stock price relationship Long positions in calls and puts have Positive Gama. For example, a gamma of .04 implies that a $1.00 increase in the price of the underlying stock will cause a call options delta to increase by .04, making the call option more sensitive to changes in stock price Gamma is highest for At-The-Money Options. Deep in the money or Deep out of the money options have Low Gamma. Gamma changes with stock prices and with time to expiration. To lower (inc) the overall Gamma in a portfolio, one should short (go long) Options
Theta
Measures the sensitivity of option prices to passage of time. As time passes, and a call option approaches maturity its speculative value declines; called Time Decay This is similar to puts, however deep in the money puts near maturity can increase in value Because theta is a measure of Time decay, it is less than zero as time passes and an option approaches maturity
Rho
Measures the sensitivity of the option price to changes in the risk free rate. Call option value increases aa the RF rate increases Put option value decreases as the RF rate increase
The Ho-Lee Model
Model assumes that changes in the yield curve are consistent with a no arbitrage condition This model is calibrated by using market prices to find the time dependent drift term 0t, that generates the current term structure. The Ho-Lee model can be used to price zero coupon bonds and to determine spot curve. The model produces a symmetrical distribution of future rates
Regarding volatility of term structure, research indicates that volatility in short term rates is most strongly linked to uncertainty regarding:
Monetary policy
When measuring Value Added by active management, it is most accurate to state that the active weights in an actively managed portfolio :
Must be positively correlated with realized asset returns for value added to be positive
Economic Value Determinants of REITs
National GDP growth is the largest driver of economic value for all REIT types. Overall growth in the economy means more jobs, more need for office space, more disposable income, more growth in shopping centers, more demand for hotel rooms from business and leisure travelers and so on
Market Fragmentation
Occurs when a security trades in multiple markets. There may be significant liquidity differences between these markets.
Economic Obsolescence
Occurs when new construction is not feasible under current economic conditions
Locational Obsolescence
Occurs when the location is no longer optimal.

Quantitative Measures of a PE firm
Paid In Capital (PIC): Capital utilized by GP Distributed to paid in capital (DPI): This measures the LPs realized returns, and is cumulative distributions paid to the LPs dividend by the Cumulative invested capital. It is net of fees and carried interest, also called Cash on cash return Residual Value to paid in capital (RVPI): This measures the LP's unrealized return and is the value of the LPs holdings in the fund / cumulative invested capital. Net of fees and carried interest Total value to paid in capital (TVPI): This measures the LP's realized and unrealized return and is the sum of DPI and RVPI. It is net of fees and carried interest

Using the DCF method for Real Estate uses the following estimates and assumptions
Project income from existing leases: It is necessary to track the start and end dates and the various components of each lease. Such as base rent, Index Adjustments, and expense reimbursements from tenants Lease renewal assumptions: may require estimating the probability of renewal Operating expense assumptions: Operating expenses can be classified as fixed, variable, or hybrid of the two. Variable expenses vary with occupancy, while fixed expenses do not. Fixed Expenses can change because of inflation Capital Expenditures and assumptions: Expenditures for CAPEX improvements, such as roof replacement, are lumpy. Consequently some appraisers average the CPAEX and deduct a portion each year instead of actual amount when paid. Vacancy assumptions: It is necessary to estimate how long before currently vacant space is leased Estimated resale price: A holding period that extends beyond the existing leases should be chosen. This will make it easier to estimate the resale price because all leases will reflect current market rents Appropriate discount rates: The discount rate is not directly observable, but some analysts use buyer surveys are guides. the discount rate should be higher than the mortgage rate because there is more risk and should reflect the riskiness of the investment relative to alternatives

Key differences between Macroeconomic Factor model and the Fundamental Factor Model:
Sensitivities: The standardized sensitivities in the Fundamental Factor Model (bi1, bi2) are calculated directly from the attribute (e.g P/E) Data-- they are not estimates. This contrasts with the Macroeconomic model in which the sensitivities are regression slope estimates Interpretation of Factors: The macroeconomic factors (Fgdp and Fqs) are surprises in the macro variables (e.g inflation or stock shock) In contrast the fundamental model factors (Fp/e and Fsize) are rates of return associated with each factor and are estimated using a multiple regression Intercept Term: The intercept in the macroeconomic model equates the stocks expected return (based on market consensus of the expectations of the macro factors) from an equilibrium pricing model like the APT. In contrast the Intercept of the Fundamental value model with standardized sensitivities has no economic interpretation; it is simply the regression intercept necessary to make unsystematic risk of asset = 0
The protection buyers of a CDS is:
Short Credit risk and hence benefits when the credit spread widens
Local Expectations Theory (Does not hold)
Similar to unbiased theory, but this theory preserves the risk neutrality assumption; ONLY for short holding periods. In other words, over longer periods, risk premiums exists. This implies that over the short term (even risky long maturity bonds) will earn the Risk free Rate
Busted Convertible
Sometimes the price of the common stock associated with a convertible issue is so low that it has little or no effect on the convertibles market price, the bond trades as though it is a straight bond
Insurance theory for Futures return
States that the desire of commodity producers to reduce their price risk drives commodity futures return. producers face uncertainty about the price they will receive for their output and reduce this uncertainty by selling futures contracts. The selling drives down the price. The insurance theory states that the futures prices will be less than current spot prices to provide a return to those buying futures from producers

Steps for Calculating an FRA before Settlement date
Step 1) Find the "New" FRA price on the X-day Loan, T- X days from now, at the current x-day rate Step 2) Calculate the Interest Difference on the principal amount for the new loan compared to the old loan then multiply it by notional Step 3) Discount the amount of interest difference at the rate that makes the difference between new and old FRA ,maturity wise, equate
Steps to value a Currency swap AFTER initiation
Step 1) First calculate the discount factors for the period that changed for both currencies; in this example it a 5m swap, you want to take the equivalent of a bond, that makes a coupon payment in X days of (Principal of bond * quarterly rate). This amount of the bond + coupon is then discounted to the present using the correct discount factor for the currency Step 2) Next calculate the value after X days on the opposite currency side doing the same as above. 3)Then convert the bond + coupon discounted to the correct currency, and to get the value of the received currency, subtract the two in the same currency to get the difference
Steps for Calculating Effective Duration and effective convexity
Step 1) Given assumptions about benchmark rates, interest rate vol, and any call/puts, calculate the OAS for the issue using the current market price and the binomial model Step 2) Impose a small parallel shift in the benchmark yield curve by an amount equal to +Change Y Step 3) Build a new binomial interest rate tree using the new yield curve Step 4) Add the OAS from step 1 to each of the 1 year rates in the IRT to get a Modified tree Step 5) Compute the BV+ChangeY using modified tree Step 6) Repeat steps 2-5 using a parallel shift of - change Y to obtain the value of BV-ChangeY
Calculations using the NPV Venture Capital Method and a Single Financing round

Step 2) Calculate PRE; PRE is what the company would hypothetically be worth without investment = POST - Capital investment Step 3) Calc f; f = F.V(INV) / POST f represents the % of the firm the VC must own Step 4) Calc SharesVC = Shares (founder) * (f/1-f) Step 5) Calc P; P = INV / Shares (vc)
Compare effective convexity of callable, putable, and straight bonds
Straight Bonds have positive effective Convexity: The increase in the value of an option free bond is higher when rates fall than the decrease in the value when rates increase by an equal amount. When rates are high, callable bonds are unlikely to be called and will exhibit positive convexity. When the underlying call option is near the money, its effective convexity turns negative; the upside potential of the bonds price is limited due to the call (While downside is not protected). Putable bonds exhibit convexity throughout
What has positive convexity at all interest rate levels?
Straight and Putable Bonds
Which bond tends to have highest effective duration?
Straight bonds, tend to have higher EffDurs than bonds with embedded options
Vasicek Model (interest Rates)
Suggests that interest rates are mean reverting to some long run value Main disadvantage is that this model does not force interest rates to be non-negative
Swap Spread =

When assumed volatility in a binomial tree increases:
The computed value of OAS will decrease. When an analyst uses a lower than actual level of volatility, the computed OAS for a Callable Bond will be too High. OAS spread decrease as implied volatility increases
Advantages of VaR
The concept of VaR is simple and easy to explain VaR allows the risk of different portfolios, asset classes, or trading operations to be compared to gain a sense of relative risk VaR can be used for performance evaluations When allocating capital to various trading units, a firms risk managers can also look at the allocation of VaR and optimize the allocation of capital given the firms determination of the maximum VaR that the organization should be exposed to Global banking regulators accept VaR as a measure of financial risk Reliability of VaR can be verified Via back testing

Key points about Real Risk Free Rate and the Inter-Temporal Rate of substitution
The higher the utility investors attach for current consumption relative to future consumption, the higher the real risk free rate will be Diminishing marginal utility of wealth means that an investors marginal utility of consumption declines as wealth increases. This suggests that marginal utility of consumption is higher during periods of scarcity If investors expect higher incomes in the future, their expected marginal utility of future consumption is decreased relative to current consumption. When investors expectations about the economy change to better economic times ahead, the expectation of higher incomes in the future will lead to an increase in current consumption relative to future consumption and would therefore save less. conversely investors expecting worse time ahead would prefer to increase future consumption by reducing current consumption and saving more Investors increase their savings rate when expected returns are higher or when uncertainty about their future income increases
The portfolio with the highest information ratio will also be the portfolio with
The highest sharpe ratio
Principal risks of REITs
The most risky REITs are those that invest in property sectors where significant mismatch between supply and demance are likely (particularly healthcare, hotels, and office reits), as well as those sectors where the occupancy rates are most likely to fluctuate within a short period of time. Also risks appear from riskiness of the properties in place
The Long Position in an FRA is:
The party that is effectively borrowing money (Long the loan, with the contract price being the interest rate on the loan) If the floating rate at contract expiration is above the specified rate in the FRA, the long position in the contract can be viewed as the right to borrow at below market rates, and the long will receive a payment. If the floating rate at expiration date is below the rate specified in the contract, the short will receive a cash payment from the long

Commodity Volatility Swap
The underlying factor is the volatility of the commodity price. If the volatility of the price is higher than the expected level of volatility specified in the swap, the volatility buyer receives a payment. When actual Vol. is Lower, than specified level, the Vol seller receives payment
An option on a Futures contract can be thought as the following:
The value of a call option on futures is equal to the value of a portfolio with a long futures position (the PV of the futures price multiples by N(d1)) and a short bond position (The pv of the exercise price multiplied by N(d2)) The value of a put option is equal to the value of a portfolioo with a long bond and a short futures position The value of a Call can also be thought as of the present value of the difference between the futures price (ADJUSTED BY n(D1)) and the exercise price (adjusted by N(d2))
Basis Swap
The variable payments are based on the difference between the prices of two commodities. often the two commodities are one that has liquid traded futures available for hedging and the other with no liquid futures contracts available. because the price changes of the two commodities are less than perfectly correlated, the difference between them (the basis) changes over time. By combining a hedge using the liquid futures with a basis swap, the swap buyer can hedge the price risk he faces from the input that does not have a liquid futures market
Option values on bonds are positively related to:
The volatility of their underlying. When interest rate volatility increases, the value of both call and put options increase
Hedging Pressure Hypothesis for Futures return
This theory expands on the Insurance theory. It adds hedging behavior of commodity consumers to the insurance theory.

Typical risk measures used include: The size of a position Sensitivity measures of interest rate and market risk Historical and hypothetical scenario analysis and option risk Active Share: The difference between the weight of a security in the portfolio and its weight in the benchmark
Direct Capitalization Method for real estate
Under this method, a cap rate or income multiplier is applied to first year NOI. Implicit in the cap rate or multiplier is the expected increases in growth
Limitations of VWAP Transaction Costs
VWAP is not useful if the trade being evaluated is a significant part of the trading volume. In such cases, the benchmark VWAP and the trade VWAP will be close to each other VWAP does not capture the price impact cost. For example, if a large buy order was the only trade that was executed during a time interval at a price above the normal trading price, the benchmark VWAP will then be identical to the trade VWAP and the calculated transaction cost will be zero, however, trade was not executed at a good price
Limitation of VaR
VaR estimations require many chjoices and can be very significantly affected by those choices The assumption of normality leads to underestimates of downside risk becuase actual returns distributions frequently have 'fatter tails' than a normal dist. Liquidity often falls significantly when asset prices fall. VaR does not account for this It is well known that correlations increased, or spike during periods of financial stress. Increasing Correlations mean that VaR measures based on normal level of correlation will overestimate diversification benefits While VaR is a single number that can be used to quantify risk, as with any summary measure, many aspects of risk are not quantified or included VaR focuses only on downside risk and extreme negative outcomes
Limitations of Effective Spread
When a large order is split into smaller orders, the effective spread is a poor indicator of trade performance because it does not take into account the price impact of costs Effective spread also does not account for slippage or delay costs when part of the order does not get filled at desired prices Sometimes the market price will move unfavorably, voiding a trading opportunity
Most likely to experience an Increase in EffDur due to an Increase in Interest Rates
When interest rates increase, a callable bond becomes Less Likely to be called (Therefore duration increases). The put option in a putable bond would be more likely to be exercised in a rising interest rate environment, hence the duration of a putable bond would decrease. Duration of an option free bond would also decrease as interest rates increase
The following comparisons can be made between ownership of the underlying stock and the risk return characterisitics of a convertible bond
When the stocks price falls, the returns on convertible bonds exceeds those of the stock, because the convertible bonds price has a floor equal to its straight bond value When the stock price rises, the bond will underperform because of the conversion premium. This is the main drawback of investing in convertible bonds versus investing directly in stocks If the stocks price remains stable, the return on a convertible bond may exceed the stocks return due to the coupon payments received from the bond, assuming no change in interest rates or credit risk affect the issues
Term and reversion approach
Whereby the contract (term) rent and the reversion are appraised separately using different cap rates
Available Commodity Indexes differ in the following dimensions:
Which commodities are included The weighting of the Commodities in the index The method of rolling contracts over as they near expiration The method of rebalancing portfolio weights
Interest rate changes on Effective Duration
While effDur of straight bonds is relatively indifferent by changes in interest rates; an Increase (DEC) in rates would Decrease Effective Duration on a Putable (Callable) bond
Breadth is most likely to be equal to the number of securities multiplied by the number of decision periods per year if active returns are correlated:
With active weights BR is intended to measure the number of independent decisions that an investor makes each years
I Spread =
Yield on bond - Swap Rate
Segmented Markets Theory
Yields are Not Determined by Liquidity premiums and expected spot rates. Rather, the shape of the yield curve is determined by the preferences of borrowers and lenders, which drives the balance between supply of and demand for loans of different maturities. The theory suggests that the yield at each maturity is determined independently of the yields at other maturities; we can think of each maturity to be essentially unrelated to other maturities This theory suggests that various market participants deal in securities of a particular maturity because they are prevented from operating at different maturities
Z-Spread
Zero Volatility Spread, is the spread that when ADDED to each spot rate on the default free spot curve, makes the PV of a Bonds Cash Flows Equal To Bonds Market Price therefore, Z-Spread is the spread over the entire spot rate curve
Structural models of Corporate credit risk
are based on the structure of a company's balance sheet and rely on insight provided by the option pricing theory They explain why default occurs
Fundamental factor models
assume asset returns are explained by multiple firm specific factors (eg. p/e., market cap)
Reconciliation of Value
because of different assumptions and availability of data, the three valuation approaches are likely to yield different value estimates. An important part of the appraisal process involves determining the final estimate of value by reconciling the differences in the three approaches
Prepayment risk differs from call risk by
being affected not only by the level of interest rate at a particular point in time, but also, by the path the rates took to get there
A swap of returns on two different stocks cant be viewed as
buying one stock (receiving returns) and shorting an equal value of another stock (Paying the returns). There is no "Pricing" at swap initiation, and we can value the swap at any point by taking the difference in returns * notional principal
A decrease in stock price volatility will decrease the value of the
embedded call on the stock (But have no effect on the embedded call on the bond) and decrease the value of the convertible bond
The owner of a convertible bond:
has the right to convert the bond into a fixed number of common shares of the issuer during a specified time frame (Conversion period) and at a fixed amount of money (Conversion Price). Convertibles allow inventors to enjoy the upside on the issuers stock, although this comes at a cost of lower yield The issuer of a convertible bond benefits from a lower borrowing cost, but existing shareholders may face dilution if the conversion option is exercised
Estate Put
includes a provision that allows the heirs of an investor to put the bond back to the issuer upon the death of the investor. The value of this contingent put option is inversely related to the investors life expectancy; the shorter the life expectancy the higher the value

The modern term structure model that is most likely to precisely generate the current term structure is
the Ho-Lee Model
Statistical factor model
uses statistical methods to explain asset returns. Two primary types of stat models are used: Factor analysis; portfolios that explain covariance in asset returns Principal component models: factors are portfolios that explain the variance in asset returns: Major weakness is that stat factors do not lend themselves well to economic interpretation
Forward Pricing Model
values forward contracts by using an arbitrage argument that equates buying a zero-coupon bond to entering into a forward contract to buy a zero-coupon bond that matures at the same time: P(j+k) = PjF(j,k)
