PORTFOLIO PERFORMANCE EVALUATION Flashcards
Describe the three interrelated components of performance evaluation
Performance measurement : What performance did the fund achieve during the period?
Performance attribution : How did the manager achieve this performance ?
Performance appraisal : Was this performance based on skill or luck ?
Contrast micro-attribution vs macro-attribution
Micro-attribution analyzes the portfolio at the portfolio’s manager’s level and seek to verify if the portfolio did what they said they would.
Macro-attribution analyzes the portfolio at the fund sponsors level.
Describe the three main approaches to conduct performance attribution
- Returns-based : Regress the portfolio returns based on major risk factors (size, value, market) to identify the active bets that the manager did.
- Holdings based : Use beginning of period holdings to assess the active sectors/stock selection bets of the manager and their contribution to active return. Drawback, it doesn’t take into consideration the change in position during the period.
Transaction based : Improvement of the holding based approach by including the impact of any trades executed during the period.
In the Brinson-Hood-Beebower (BHB) Method, what are the three components of of active returns and how we calculate them.
Allocation effect : Active weights * Benchmark segment Return
Selection Effect : Active return * Benchmark weight
Interaction effect : Active weight * Active return
In the Brinson-Fachler (BF) Method, what are the three components of of active returns and how we calculate them.
Allocation effect : Active weights * (Benchmark segment return - total Benchmark Return)
Selection Effect : Active return * Benchmark weight
Interaction effect : Active weight * Active return
In equity attribution, describe one type of factor-based return attribution
Carhart model : Calculate the excess return from active portfolio management investment decisions by determining the impact on the portfolio due to factors like :
- Market index : Return on value weighted index compare to one month T-Bill rate
- Market Cap : Small vs big company, difference between the returns of 3 small cap company vs 3 big cap company
- Book to value price : High minus low : Difference between the average return of two high book to market portfolio vs two low book to market
- Momentum : winners minus losers - Difference between the returns on a portfolio of the past years winners and the return on a portfolio past years losers
Describe what are the three common methods of fixed income attribution
Exposure Decomposition - Duration based : Duration, curve shape, sector selection and bond selection
Yield curve decomposition - Duration based : Yield or income, roll, shift, shape, spread and residual
Yield curve decomposition - full-repricing based : Breaks down the active return of the manager using individual spot rates for cash flows occuring at different maturities. Most precise approach but most complex.
Define the primary types of benchmark
- Absolute Benchmark
- Broad market indexes
- Style indexes
- Factor-model based
- Returns-based
- Manager universe
- Custom security-based
Identify the different characteristics that a benchmark has to have to be consider a valid benchmark.
SAMURAI
- Specified in advance
- Appropriate
- Measurable
- Unambiguous
- Reflective of the managers investment views
- Accountable
- Investable
Describe how a portfolio’s return can be broken down
Can be broken down by :
- Market returns : Returns on the market index
- Style Returns : Benchmark return - market returns
- Active management : Portfolio return - Benchmark return
Describe the three general type of benchmark that could be consider for hedge funds and why does it reflect some problems
Broad market index : Not appropriate since hedge funds cover a wide range of investment strategies. Low correlation with broad market indexes
Risk free rate + spread : Could be good for arbitrage strategies. Unfortunately, the vast majority of hedge funds will carry some systematic risk, and the use of leverage will only exacerbate the risk.
Hedge fund peer : Not suitable because a specific peer group’s risk and return objectives are not likely to match those of a specific hedge fund.
How do we calculate the Sharpe Ratio
Rp - RF / standard deviation assets
How do we calculate the Treynor Ratio
Rp - Rf / Beta portfolio
How do we calculate the information Ratio
Active return/Active risk
How do we calculate the Appraisal Ratio
Ratio of active return/ volatility of the residual term
Both derive from a factor based regression
To get the volatility of the error term, we can derive it from the CAPM model.
Variance of portfolio = Portfolio beta*variance of market + variance of error term from portoflio
