Performance Evaluation Flashcards
Performance from Fund Sponor’s Perspective
Performance shows the following:
- How effective IPS is
- Underperformance
- Results of active management
For feedback and control
Components of Performance Evaluation
- Performance measurement
- Performance attribution
- determines source of return
- Performance appraisal
- determine if its skill (should we fire a manager)
Return Calculation with Cash Flows
CF at beginning:
rt = EV - (BV + CF) / BV + CF
CF at end:
rt = (EV - CF) - BV0 / BV
TWR
Unaffected by external cash flows
Calculate returns subtracting cash flows then add together;
(1 + r)(1 + r)(1 +r) - 1
Example: 2.5M start, 2.7M end. 45K CF day 7, 25K CF day 19
Day 7 2.555M, day 19 $2.575M
(2,555,000-45,000) - 2,500,000 / 2,500,000 = 0.4%
(2,575,000-25,000) - 2,555,000 / 2,555,000 = -0.2%
(2,700,000) - 2,575,000 / 2,575,000 = 4.9%
(1 + .004)(1 - .002)(1 + .049) - 1 = 5.1%
MWRR
EV = BV(1 + r)n + CF(1 + r)n
Just plug in figures for r
TWRR vs. MWRR
- *TWR**
- *+** unaffected by timing of cash flows
- *+** required for GIPS
- *-** need to know valuations on each CF date
- *MWR**
- *+** good if manager controls CF
- *-** distorted by size and timing of CF
TWR vs MWRR
Which is better?
Cash Prior to _____ Performance Result
None None Same
+CF Strong MW > TW
+CF Weak TW > MW
- CF Strong TW > MW
- CF Weak MW > TW
Data Quality for Returns
- Stale price:
- Illiquid assets - use estimates
- Fixed income - use matrix
- Should include accrued interest and dividends
- Use trade date
Portfolio Return Components
P = Market + Style + Active
M = market return, Style = B - M, Active = P - B
Client responsible for S
Manager responsible for A
Example: LC Value Fund earns 18.9% for 3 quarters
Russell 1000 Value = 21.7%, Wilshire 5000 = 25.2%
Style = 21.7 - 25.2 = -3.5% Active = 18.9 - 21.7 = -2.8%
Valid Benchmark
SAMURAI
- Specified in advance
- Appropriate
- Measurable
- Unambiguous (Clear/Precise)
- Reflective of manager’s current investment opinons
- Accountable
- Investable
Types of Benchmarks
- Absolute return: i.e. 5%
- Drawback: NOT investable
- Peer group
- Drawback: subject to survivor bias, NOT investable
- Fails every quality test EXCEPT measurable
- Broad market index
- Drawback: manager style may deviate
- Style index
- Drawback: different definitions of style
- Factor-based models
- Return-based
- Custom
Testing Benchmark Quality
- Mutually exclusive with indices/asset classes
- Exhaustive of manager’s investment universe
- Represent distinct sources of risk
Hedge Fund Benchmarks
Hard to assign a benchmark. Use:
- Value-added return for each position
- Separate long/short benchmarks
- sharpe ratio often used but not appropriate
- Market neutral should be Rf
Macro Attribution Analysis Levels
Beginning Value
- Net contribution
- Rf
- Asset categories (pure indexing SAA from IPS)
- Benchmarks (pure indexing TAA from manager)
- Investment managers (active management)
- Allocation effects (error/plug number)
* *Ending Value**
Micro Attribution Components
Pure Sector Allocation
Definition: Sector deviation from benchmark
Formula:
(Wp,s - Wb,s) * (Rb,s - Rb)
