Chapter 10 Flashcards
The statistics used to measure performance must meet which requirements? (5)
- Unambiguous
- Investable
- Measurable
- Appropriate
- Specified in advance
For performance evaluation, what does unambiguously mean?
weights of securities and factor exposures of benchmarks are clearly defined
For performance evaluation, what does an investable benchmark mean?
can stop active management and just buy the benchmark as a passive portfolio
For performance evaluation, what does measurable mean?
returns and risk of portfolio can be calculated quickly and frequently
For performance evaluation, what does an appropriate benchmark mean?
the benchmark is consistent with the manager’s investment style or area of expertise
For performance evaluation, what does specified in advance mean?
stated on the IPS and is known to all parties
What is peer group benchmarking?
has the manager outperformed peer group’s median performance?
What is a critique of peer group benchmarking? (3)
the investment decision will be based on what other fund managers are doing
creates herding mentality
everyone else could be bad but the least bad will be shown as the best - even though absolute performance is still poor
When is customised benchmarking appropriate? (2)
asset allocation decision and stock selection decisions are separable
e.g. asset allocation decided by trustee, stock selection done by fund managers
What happens when limits set on customised benchmarking are set tight?
might make the portfolio a pseudo tracker
For performance evaluation, what is objectivity?
historic performance is analysed against some baseline
not open to dispute
For performance evaluation, what is subjective? (3)
involves making predictions about the future
there is no way to perfectly model economic systems
use subjective views
Why is performance evaluation required?
compares managers’ performance
show if portfolio meets requirements
What is absolute performance?
an absolute return can simply be a return objective, without reference to any another benchmark or similar comparator
What does absolute performance aim to show?
whether total return is commensurate with total risk experience
What should a suitable performance measure include?
return target and risk target
How does an absolute performance measure help an investor?
helps understand whether return offered is appropriate to level of risk taken
What is relative performance?
return compared to benchmark or peers
What are the three standard risk-adjusted measures?
jensens
sharpe
treynor
What is jensens measure?
post alpha return
uses beta
What is sharpe ratio?
return of portfolio measured in standard deviation terms
