A
19
Q

Incremental return contribution of the benchmarks strategy

A
  • rIS is the incremental return contribution of the Benchmarks strategy
  • rBij is the return for the jth manager’s benchmark in asset category i
  • rCi is the return on the ith asset category
  • wi is the policy weight assigned to the ith asset category
  • wij is the policy weight assigned to the jth manager in asset category i
  • A and M are the number of asset categories and managers, respectively
20
Q

Incremental return contribution of the active management strategy

A
  • rAij represents the actual return on the jth manager’s portfolio within asset category i
  • rBij is the return for the jth manager’s benchmark in asset category i
  • rCi is the return on the ith asset category
  • wi is the policy weight assigned to the ith asset category
  • wij is the policy weight assigned to the jth manager in asset category i
  • A and M are the number of asset categories and managers, respectively
21
Q

Sector weighting/stock selection attribution

A
  • wpj = Portfolio weight of sector j
  • wBj = benchmark weight of sector j
  • rpj = Portfolio return of sector j
  • rBj = benchmark return of sector j
  • S = number of sectors
22
Q

Hypothesis testing error types

A
  • Type I error—keeping (or hiring) managers with zero value-added. (Rejecting the null hypothesis when it is correct.)
  • Type II error—firing (or not hiring) managers with positive value-added. (Not rejecting the null hypothesis when it is incorrect.)
23
Q

Target active risk, max sector deviation and max risk contribution for a single security for the 3 following approaches:

  • Diversified multi-factor
  • Sock picking
  • Sector rotation
A
  • Diversified multi-factor
    • Target active risk → low
    • Max Sector deviation → medium
    • Max. risk contribution for a single security → low
  • Stock picking
    • Target active risk → high
    • Max Sector deviation → low
    • Max. risk contribution for a single security → medium to high
  • Sector rotaiton
    • Target active risk → high
    • Max Sector deviation → high
    • Max. risk contribution for a single security → low
24
Q

Information coefficient (IC) - formula

/

IC is the ex ante risk-weighted correlation

A
  • σi is the forecasted volatility of the active return on security i
  • μi is the forecasted active return
25
Q

E(RA) of the full fundamental law

A
26
Q

Information ratio (IR) of the full fundamental law

A
  • Unconstrained → IR = (IC)√BR
  • Constrained → IR = (TC)(IC)√BR
27
Q

Transfer coefficient (TC) - definition

A

The TC is the cross-sectional correlation between the forecasted active security returns and the actual active weights, adjusted for risk

28
Q

Transfer coefficient (TC) - formula

A
  • σi is the forecasted volatility of the active return on security i
  • μi is the forecasted active return
29
Q

Fixed-income management effect

A
  • Interest rate management effect: Indicates how well the manager predicts interest rate changes. To calculate this return, each security in the portfolio is priced as if it were a default-free security. The interest rate management contribution is calculated by subtracting the return of the entire Treasury universe from the aggregate return of these repriced securities. The interest rate management effect can be further broken down into returns due to duration, convexity, and yield-curve shape change
  • Sector/quality effect: Measures the manager’s ability to select the “right” issuing sector and quality group. The sector/quality return is estimated by repricing each security in the portfolio using the average yield premium in its respective category. A gross return can be then calculated based on this price. The return from the sector/quality effect is calculated by subtracting the external effect and the interest rate management effect from this gross return
  • Security selection effect: Measures how the return of a specific security within its sector relates to the average performance of the sector. The security selection effect for each security is the total return of a security minus all the other components. The portfolio security selection effect is the market-value weighted average of all the individual security selection effects
  • Trading activity: Captures the effect of sales and purchases of bonds over a given period and is the total portfolio return minus all the other components.
30
Q

Steps in creating a custom security-based benchmark

A
  • Identify prominent aspects of the manager’s investment process
  • Select securities consistent with that investment process
  • Devise a weighting scheme for the benchmark securities
  • Including a cash position
  • Review the preliminary benchmark and make modifications
  • Rebalance the benchmark portfolio on a predetermined schedule

Q

3 main features for independent variables used in a return-based style analysis

A
  • Mutually exclusive
  • Exhaustive
  • Represent distinct sources of risk
35
Q

R-square in a return-based style analysis

A
  • The R-squared resulting from a regression against a benchmark represents passive management → R-squared is the variation that can be explained by the variation of the benchmark and is therefore passive
  • (1 - R-squared) represents active management
36
Q

Advantages of holdings-based analysis versus return-based style analysis

A
  • The method characterizes each position rather than looking only at the portfolio as a whole
  • The method facilitates the comparison of individual positions
  • The method is likely to capture changes in style more quickly
