The two period active return for a portfolio can be determined by: A)
| compounding the individual one period active returns. |
| B)
| taking the active return on the portfolio in the first period multiplied by the return on the benchmark in the second period plus the active return in the second period multiplied by the total return on the portfolio in the first period. |
| C)
| maintaining the same security or market allocation proportions for each period, compounding the individual one period active returns for each attribute, and then summing the compounded returns to get an overall total active return. |
|
To measure the overall return to active management we use the following formula:RA,2 = Ra,1(1 + Rb,2) + Ra,2(1 + Rp,1)
Where:
RA,2 = the two-period active return
Ra,1 = active return for period 1
Rb,2 = return of the benchmark in period 2
Ra,2 = active return for period 2
Rp,1 = return on the portfolio for period 1
The first term in the equation, Ra,1(1 + Rb,2), is the active return on the portfolio in the first period multiplied by the return on the benchmark in the second period. It shows the value added by the manager’s actions in the first period. The active return in the first period will compound at least at the benchmark rate of return over the second period, even if the manager pursues a pure indexing strategy in that period.
The second term, Ra,2(1 + Rp,1), takes into account the manager’s active decisions in the second period. It is measured as the active return in the second period multiplied by the total return on the portfolio in the first period.- The multiple-period return to active management for an individual attribute cannot be determined by adding or compounding the attribute’s contributions in each period.
- The multiple-period return to active management for an individual attribute cannot be determined by assuming it stays at the same proportion of the active return in each period.
