Measures of Investment Returns Flashcards
simple vs compound return
simple return: arithmetic mean (may not reflect actual return outcome for investors)
compounding return: involves adding interest to principal in order to calculate interest in their next period
Geometric mean
Geometric mean: (time weighted return) reflects compound returns over more than one time period
- used to find average of numbers as percentages
- used to measure change of wealth over multiple periods
- used to evaluate performance of investment manager
Geometric mean calculation
- Add 1 to the returns expressed as a decimal ( 25%, 1.25: 15%, 1.15: -12%, .88
- Multiply the returns results of step 1
- The result of step 2 becomes the FV
- -1 is always PV
- N is the number of years of the investment
- solve for i
Time weighted return
measures investment performance (income and price changes) as a percentage of capital at work
- eliminates effects of additions and withdrawals and their timing that distort dollar weighted return
Dollar weighted return
measures change in total dollar value, treating additions and withdrawals of capital as part of the return along with income and capital gains and losses
- IRR/NPV
- enables investors to compare absolute dollar amounts with financial goals
- manager to manager comparison not possible
Real rate of return
(inflation adj. interest rate)
- nominal rate of return adjusted for inflation
IRR = [(1+after tax return / 1+inflation rate) -1] * 100
Nominal return
actual returns produced over a given time period without accounting for the purchasing power of the dollar inflation
Total return
annual return on an investment including appreciation or loss and dividends or interest
Risk adjusted return
return has been altered to account for the difference in risk among variables of the same type
Holding period return (HPR)
- total return over period from purchase to end of period or sale dividend (end of period) by the price of the investment
- weakness: fails to consider the timing of when the cash flow occurred. if the time period is over 1 year, the HPR overstates the true annualized return. less than one year then understates
- calculate: income + price appreciation + dividends ( margin interest + -purchase price) / purchase price
Return / Basis = HPR
Internal Rate of Return (IRR)
- discount rate at which the present value of future cash flows equals the cost of the investment
- when the NPV of cash flow is zero, the discount rate being used is the IRR
- when IRR > required return its a good investment
Yield to maturity
- effective yield of a bond
- compounded rate of return an investor will receive from a bond at the current market price if held to maturity
- accounts for market price and capital gains or losses on bond if held to maturity
- always use semiannual compounding, even with 0 coupon bonds
YTM and reinvestment rate risk
- YTM assumes bond holder reinvests all coupons received from a bond at a rate equal to its computed YTM
- if investor spends coupon or reinvests them at a rate different than YTM then realized yield will be different from YTM
- zero coupons eliminate reinvestment rate risk
Yield to call
presumes that the bond will be redeemed by the issuer at the first call date specified in the indenture agreement
- most corporate and some government bonds are callable
- essentially same as YTM except the principal value at maturity is replaced by the call price and maturity date (years) is replaced by the first call date
Current yield
- takes into account the interest in dollars and current market price of the bond
- does not factor any discount or premium
CY = annual interest in dollars / bonds current price
