Lesson 2: Risk & Return
the degree of return over and above the rate of inflation
real rate of return
rate of return used to adjust for inflation
real rate of return 1+R / 1+i - 1 x 100
rate of return an investor must earn on an investment to be fully compensated for its risk
required rate of return
a reward for investing
return
additional return needed due to relative risk of the investment compared to other, safer investment choices
risk Premium
a measure of risk or total return variability and includes systematic and unsystematic influences on asset returns measures average distance of annual returns from the average(mean) return
standard Deviation
Does beta measure systematic or unsystematic risk?
systematic
primary sources of risk
systematic or :market Driven Risk & Unsystematic or Unique (specific to secuirty)
ho do we quantify investment return
this is not a straight fwd answer. there are MANY ways to calculate 1. Holding period return 2. Arithmetic Mean Return 3. Geometric mean return 4. Internal Rate of return (Dollar-weighted Return) 5. Annualized Return 6. After tax return 7. Real Return
Seth bought ABC stock for $21 per share 6 months ago. Seth sold ABC today for $29.40 per share. What is his annualized return?
96%
annualized Return Eqn
= (1+Rp)^N - 1 Rp = return for the period being measured (month, quarterm days, etc.) N = number of periods on a year(12, 4 , 365,e tc)

Parker buys a stock for $60 and receives dividends of $10. He then sells the stock for $100. What is his holding period return? Was this a good return?
(100-60)+10 / 60 = 83.3% good return but we don't know the holding period

What is the holding period return (HPR) of an investment that cost $100, paid $25 over its term, and was sold for $150?
75%
assumes cashflow (interest/dividends) are reinvested at the same rate for a holding period of 1 year
Annualized Return
the percentage change in the investment's value from the beginning to the end of the period.
Appreciation new-old / old
a simple average return and uses the same formula you've likely seen since you were in elementary school
Arithmetic Mean Return should never be used when finding rates of returns
an indication of a securities volatility relative to the market

Beta
examples of unsystematic risk
Business - risk specific to a business (ops, mgmt, earnings) Country - uncertainty due to international politics financial - capital structure of the firm govt/regulation - risk of tariffs credit crisk, default risk, event risk, liquidity risk
Which of the following is a systematic risk? Country risk Exchange rate risk Financial risk Business risk
Exchange rate risk
calculates the average return over time, assuming all earnings remain invested. Calculates the compound annual return, not the simple average
Geometric Mean Return (GMR) aka TWRR or Time weighted Rate of Return
Holding Period Return eqn

a measure of return that includes capital appreciation or loss and current income
Holding Period Return *Most significant when Holding period is one year
At the beginning of Year 1, an investor buys one share of Good Chips stock for $12. At the end of Year 1, the investor receives a dividend of $1 and buys another share of Good Chip stock for $16. At the end of Year 2, the investor sells both shares for $20 each. Dollar Weighted Rate of Return (IRR)? Time Weighted Rate of Return (GMR)?
IRR = 30.48 (-12 CFj, -15 CFj, 40CFj, IRR = 30.48%) GMR for one share = -12 CFj, 1 CFj, 20CFj, IRR = 33.33%

examples of systematic risks
Purchasing Power Risk Reinvestment Rate Risk Interest Rate Risk Market Risk Exchange Rate Risk
involves the uncertainty of future outcomes or the possibility of an adverse result
Risk
risks that are inherent in the "system". these are non-diversifiable, regardless of how many securities and industries are combined in a portfolio.
Systematic risks
risk that can be diversified away by combining multiple asset classes and industries in a portfolio
Unsystematic risk
the amount of cash the investment pays back to the investor on a regular basis - expressed as a percentage of the amount invested.
Yield
arithmetic mean
calculated by totaling all the results and dividing by the number of results
A risk due to uncertainty surrounding the outcome of an election is known as a business risk. country risk. financial risk. interest rate risk.
country risk.
the investor's expectations of inflation
expected inflation premium
the return an investor believes an investment will earn in the future.
expected return
data is peaked at the mean and has more observations in the tail
high Kurtosis aka leptokurtic date
expected returns depend on many internal and external forces
internal: Historical return, expected risk, type of investment vehicle, quality of management, how the investment is financed, size of customer base external: Fed reserve actions, shortages, war, price control, political events
dollar weighted returns tend to be less thatn average market returns bc many investors buy stocks after they rise in value and sell stocks after they fall in value
investor return gap
data has a relatively short short peak at the mean as well as thinner tails
low kurtosis aka platykurtic data

normally distirbuted
geometric mean return
nth root of ((1+r1)(1+r2...(1+rn)) - 1 x 100 (nth root is also "to the power of 1/n)
Yield + Appreciation = ?
total return
example of positive skew for bonds
treasury bills since negative return is not possible
true or false: the arithemtic mean will alsways be greater than or equal to the geometric mean
true
