Manager selection and other Flashcards
Due diligence on investment manger
emphasize the sources and reasons behind the actual returns generated in the past
- must be an evaluation on the probability of repeated earnings sufficient or better returns in the future using the same inv. process.
Manager universe
consist of only those manager who are subtle for the portfolio in terms of the objectives and constraints of the IPS, style and will reconcile between active and passive approaches.
approaches to assign a pm to a benchmark
- 3rd party categorization
- return-based style analysis
- Holding’s based style analysis
- manager experience
Quant analysis
- evaluate objectively in terms of distribution of past returns
- perf attribution and appraisal
- capture ratio examine performance in both good and weak market conditions
= check for any significant drawdowns (peak-through decline in terms for specific time period)
quantitative analysis issue
- what is the likelihood that the same level of returns will continue in the future
- does the manager’s inv. process accurate for all the relevant risks
Philosophy:
focus on a specific arcade of market inefficiency to earn excess returns
process / people
determine whether the strategy is feasible and if it’s possible to execute the strategy with given knowledge and skills of the employees
portfolio
must be built in way that is consistent with the philosophy and process
Type I Error
reject null, no value added
ho: no value added
retain the manager with no skill
receive much more attention than type iI because:
- notion of regret aversion by the decision maker
- an error of commission
- result exploit cost
- transparent to investor
type iI error
null is not rejected, when in fact there was value added
fire the manager with skill
- errors of omission
- result in implicit/ opportunity cost
- not measurable
- not transparent
preventing type iI error
indicative of problems with the hiring and firing of managers
solution:
track the subsequent performance of managers who were not hired as well as those who were fired.
It is important not to hire or fire managers because of short term performance or because of behavior bias.
cost of type I and II errors
the greater the different in sample size and mean, the greater the cost of Type i and iI errors
- the wider the dispersion of returns between strong and weak managers, the easier its to distinguish between their relative skills
- decrease the difference in sample size and mean, increase std, the decrease the expected cost
- more efficient markets exhibits smaller difference in the dispersion of skilled and unskilled PM, result in lower costs
Type ii error occur i mean-reverting markets when strong managers are fired or managers who have weaker ST performance are fired and they subsequently outperform when market goes up.
Returns-based style analysis RBSA
Top-down approach that involve estimating the risk exposure from a n actual return rises for a given period.
adv:
straightforward, typically does not require a large amount of additional data, or difficult to acquire data
disadvantage:
- lack precision
- may not reflect the current or future portfolio exposures
- if the portfolio contains liquid securities, stale, prices may understate the risk exposure
Holding-based style analysis HSBA
(most appropriate for equity based strategies)
Bottom up approach that estimates the risk exposures from the actual securities held in the portfolio at a point in time.
adv:
- it allows for the estimation of current risk factors, proving an accurate view of the PM’s risk exposure
- comparable across PM and through time
disadvantage:
1. more computational effort required
2. high dependence on the degree of transparency provided by pM
3. stale pricing and window dressing
4. not appropriate if the portfolio has high turnover
capture ratio
> 1 POSTIVE asymmetry convex
determine how suitable a manager is with respect to the investor’s risk tolerance and time horizon
UC (upside ) look at capture when benchmark has positive return
UC > 1 outperformance
DC look at capture when benchmark has a negative return
DC < 1 outperformance
- can be used to confirm investment strategy
high beta, momentum-driven strategies, should have increase UC than value driven strategies, high UC and DC
low beta will have low UC and DC.
Drawdown
a low-beta strategy may have lower absolute return but low risk in the form of lower drawdowns may result in better risk-add returns
- useful for identifying poor/poorly executed investment strategies, weak internal controls, and operational problems
investment philosophy
exploit inefficiencies in financial market to generate excess return
behavioral inefficiency
mis-pricing caused by other investors and their behavior bias, st in nature
