Measuring Portfolio Performance Flashcards
Holding period return
The return made over the time the investment is held
Expressed as a percentage of the cost
Does not take into account tax or
timing of receipts.
D+ VI - Vo/ Vo = R
R = the holding period return D = income received Vo= value at the beginning VI= value at the end Relative Return
Money-Weighted Rate of Return
Modified form of holding period return
Adjusted for cash inflows
Calculation allows for differences in timing, weighting each by number of months remaining at
time of investment or withdrawal
The difference in value of a portfolio at the end of the period
Used to calculate valid rate of return for portfolio
Compared with the value at the start of the period (plus income/capital distributed):
D+ VI- Vo-C/
Vo+(Cxn/12)
n = number of months remaining in the year
c= new money introduced in the year
Time-Weighted Rate of Return
Attempts to eliminate distortions caused by timings of new money
By breaking down return into sub-periods:
TWR = R= V1 --- V0 x V2 --- (V1 + C) - 1
Universally used for comparative purposes because not affected by cash flows
Sharpe ratio
Return on investment - risk free return / standard deviation of the return
Alpha
Actual return - (rf + b(rm-rf)
Information ratio
Rp-rb/tracking error
Sharpe ratio explained
Measures excess return for
every unit of risk that is
taken in order to achieve
the return
Risk measured by standard
deviation of returns
Alpha explained
Difference between return
expected, given its beta, and the
return actually produced
Quantifies the value added’ or
taken away by the manager
Information ratio explained
Used to assess risk-
adjusted performance of
active portfolio managers
vs a benchmark
Higher ratio = higher added
value
