MGMT 41150 - Exam 1

one contract is the rate earned on

$1 million

contract size is

$100,000

a change of one basis point (0.01) in a Eurodollars futures quote corresponds to a contract price change of

$25

The value of a long forward contract:

(F0 - K)*e^(-rT)

The value of a short forward contract

(K - F0)*e^(-rT)

once the trader with the short position chooses a bond, the cash they receive for each $100 of face value is given by:

(P * conversion factor) + accrued interest p is the most recent futures settlement price

the short trader will choose the bond that maximizes the difference:

(P * conversion factor) - Quoted price

Asset with certain income: forward price (F0) =

(S0 - I) * e^(r * T) I is the present value of the income during life of forward contract

choice of contract

*Choose a delivery month that is as close as possible to, but later than, the end of the life of the hedge *When there is no futures contract on the asset being hedged, choose the contract whose futures price is most highly correlated with the asset price. There are then 2 components to basis. This is known as cross hedging

treasury futures contracts allow the trader with the short position to deliver bonds of different maturities at delivery: - for T-bond futures, bond can be between ____ and ____ years to maturity - for 10-year T-note futures, any bond with ____ to ____ years to maturity will suffice

- 15 and 25 - 6.5 and 10

Options vs. Futures/Forwards

- A futures/forward contract gives the holder the obligation to buy or sell at a certain price. - An option gives the holder the right to buy or sell at a certain price.

Price manipulation: Hunt brothers

- Hunt brothers accumulated gigantic futures positions and demanded delivery on those contracts as they came due - they concurrently bought a huge quantity of physical silver and held it off the market - silver price jumped from $6/ounce to $48/ounce -CFTC imposed liquidation-only trading: traders are only allowed to trade to close a futures position -known as "Silver Thursday" -Hunt brothers went bankrupt afterwards

Since 2008 ...

- OTC market has become regulated - In the US and some other countries, standardized OTC products must be traded on swap execution facilities (SEFs) which are similar to exchanges - CCPs must be used for standardized transactions between dealers in most countries - All trades must be reported to a central registry

futures contracts categories

- Physical futures (agricultural, electricity, petroleum, metals, lumber) - Financial futures ( >50% of futures market volume)

Arguments against hedging

- Shareholders are usually well diversified and can make their own hedging decisions - It may increase risk to hedge when competitors do not - Explaining a situation where there is a loss on the hedge and a gain on the underlying can be difficult

Futures contract

- agreement to buy or sell an asset for a certain price at a certain time - similar to forward contract

forward contract

- an agreement between two parties to exchange a given quantity of an asset for a given price at a specific date in the future - these trade OTC and are usually negotiated between two large institutions

Futures contracts

- available on a wide range of assets - exchange traded - specifications need to be defined: what can be delivered, where it can be delivered, when it can be delivered (month long contracts0 - settled daily

Arguments for hedging

- companies should focus on the main business they are in and take steps to minimize risks arising from interest rates, exchange rates, and other market variables - company can likely hedge for a lower cost than shareholders

at time T

- deliver underlying, and make payment - zero sum game: the winner's profit is the loser's loss

forward price

- delivery price that would be applicable to the contract if it were negotiated today (i.e., it is the delivery price that would make the contract worth exactly zero) - the forward price may be different for contracts of different maturities

mutual funds must:

- disclose investment policies - make shares redeemable at any time - limit use of leverage

forward market is self-regulated:

- forward contracts are traded OTC - forward contracts are not standardized - forward contracts don't have explicit margin requirements

The OTC market prior to 2008

- largely unregulated - banks acted as market makers quoting bids and offers - master agreements usually defined how transactions between two parties would be handled - But some transactions were handled by central counterparties (CCPs). A CCP stands between the two sides to a transaction in the same way that an exchange does

Reasons to hedge a stock portfolio

- may be out of the market for a while. Hedging avoids the costs of selling and repurchasing the portfolio - suppose stocks in your portfolio have an average beta of 1.0, but you feel they have been chosen well and will outperform the market in both good and bad times. Hedging ensures that the return you earn is the risk-free return plus the excess return of your portfolio over the market

How derivates are traded

- on exchanges such as the Chicago Board Options Exchange - In the over-the-counter (OTC) market where traders working for banks, fund managers and corporate treasurers contact each other directly (these exchanges are privately negotiated)

basis risk

- risk attributable to uncertain movements in the spread between a futures price and a spot price - usually defined as the spot price of the asset being hedged minus the futures price of the contract used for the hedge - arises because of the uncertainty about the basis when the hedge is closed out

important features of futures

- settled daily - closing out a futures position involves entering into an outsetting trade - most contracts are closed out before maturity - if a futures contract is not closed out before maturity, it is usually settled by delivering the assets underlying the contract, When there are alternatives about what is delivered, where it is delivered, and when it is delivered, the party with the short position chooses - a few contracts (for example, those on stock indices and Eurodollars) are settled in cash

not the spot price

- spot price is the price for delivering the underlying right now - forward price is the price for delivering in the future

At time t

- the counterparties enter the contract - the value of the contract is zero at t, so no money changes hands - net number of outstanding contracts is always zero in the market: Number of long = number of short

not the value of the forward contract

- the value of the forward contract is the current value fo final payoff and it changes over the life of forward - forward price is fixed over the life of the forward

How derivates are used

- to hedge risks - to speculate (take a view on the future direction of the market) - to lock in an arbitrage profit - to change the nature of a liability - to change the nature of an investment without incurring the costs of selling one portfolio and buying another

Dangers

- traders can switch from being hedgers to speculators or from being arbitrageurs to speculators - it is important to set up contracts to ensure that trades are using derivatives in for their intended purpose

liquidity concerns

-in any hedging situation there is a danger that losses will be realized on the hedge while the gains on the underlying exposure are unrealized -this can create liquidity problems

types of orders

-market order -limit order -stop-loss order -stop-limit order -market-if-touched order

if Q is the quoted price of a Eurodollar futures contract, the value per contract is:

10,000 * [100 - 0.25(100 - Q)] this equation corresponds to the $25 per basis point rule

the final settlement price is

100-R, where R is the actual 3-month LIBOR on that day

day count - corporate and muni bonds

30/360

treasury bonds are quoted in _____ of a dollar

32nds

Optimal Number of Contracts if no adjustment for daily settlement

= (h* Qa) / Qf Qa = size of position being hedged (units) Qf = size of one futures contract (units)

Optimal number of contracts after "tailing adjustments" to account for daily settlement of futures

=(h^ * Va) / Vf Va = value of position being hedged (=spot price * Qa) Vf = value of one futures contract (=futures price * Qf)

American vs. European Options

An American option can be exercised at any time during its life A European option can be exercised only at maturity

if a stock is trading at a different price in New York and Tokyo what should you do?

Arbitrage trade is: buy at the lower price and immediately sell at the higher price

Hedging Using Index Futures: to hedge the risk in a portfolio, the number of contracts that should be shorted is

B*(Va / Vf) Va = value of the portfolio B = portfolio beta Vf = value of one futures contract

stock going up?

Buy a call

How are forward contracts usually closed?

By delivering the asset

PV =

CF * e^(-r * t)

FV=

CF * e^(r *t)

the forward price equation:

F = S(1 + r)^T

Forward price

F(t,T) = K

Asset with a known yield: forward price (F0) =

F0 = S0 * e^((r-q)*T) q is the average yield during the life of the contract (expressed with continuous compounding)

the futures price and spot price relationship is

F0 = S0*e^((r - q) *T) q is the average dividend yield on the portfolio represented by the index during the life of the contract

currency forward and futures equation

F0 = S0e^(r - rf)T rf is the foreign risk-free interest rate F and S are in USD / foreign currency

Short Hedge for Sale of an Asset: gain on futures

F1 - F2

F1 = F2 = S2 = b2 =

F1: futures price at time hedge is established F2: futures price at time asset is purchased S2: asset price at time of purchase b2: Basis at time of purchase

Long Hedge for Purchase of an Asset: gain on futures

F2 - F1

Types of traders

Hedgers, Speculators, Arbitrageurs

forward price notation

K

Short payoff =

K - ST

Types of hedge funds

Long/Short Equities, Convertible Arbitrage, Distressed Securities, Emerging Markets, Global Macro, Merger Arbitrage.

Size of OTC and Exchange traded markets

OTC market is much larger

Stack and roll

Procedure where short-term futures contracts are rolled forward so that long-term hedges are created.

Spot price of the underlying at maturity

S(T)

Spot price of the underlying at initiation

S(t)

the forward price (F0) =

S0 * e^(r * T)

Long Hedge for Purchase of an Asset: cost of asset

S2

Short Hedge for Sale of an Asset: cost of asset

S2

Short Hedge for Sale of an Asset: Net amount received

S2 + (F1 - F2) = F1 + b2

Long Hedge for Purchase of an Asset: net amount paid

S2 - (F2 - F1) = F1 + b2

spot price of asset on the delivery date

ST

Long payoff =

ST - K

basis =

St - Ft

maturity time (delivery time)

T

this means changes in the index must correspond to changes in the value of

a tradable portfolio

day count - money market instruments

actual/360

Day count - treasury bonds

who establishes a margin account

both the long and short investor

at some stage you must _______ the securities so they can be replaced in the account of the client

buy

when F0 < S0e^((r-q)*T) an arbitrageur

buys futures and shorts or sells the stocks underlying the index

Because delivery can involve many possible bonds, the trader with the short position will receive money based on the _______________ of the bond they choose to deliver

conversion factor

the balance in the margin account is adjusted to reflect

daily settlement

to find accrued interest:

day count * coupon payment

hedge funds use complex trading strategies and are big users of _________ for hedging, speculation, and arbitrage

derivatives

you must pay _______ and other benefits the owner of the securities receives

dividends

trader also has a potential wild card play

futures contract settlement price is the bond price at 2 pm Chicago time, but bonds continue to trade after this. If prices decline, they can buy them at the spot price and deliver, if not, roll it to the next day

optimal hedge ratio (h*) =

h* = (coefficient of correlation between change in S and change in F) * ((SD of the change in the spot price during the hedging period) / (SD of the change in the futures price during the hedging period))

optimal hedge ratio (h^) =

h^ = (correlation between percentage daily changes for spot and futures) * ((SD of percentage daily changes in spot) / (SD of percentage daily changes in futures))

margin calls

if the balance in the margin account falls below the maintenance margin level, then the trader will get a margin call, and has to deposit money to bring the margin account up to the initial margin level
