Enhanced
indexing (Semi active management)
Stock
based:
If a manager has no
opinion on a stock, he holds the same weight as in the index. (In full blown
active management, no opinion results in no holding)
Higher
IR.
Derivatives-based:
To gain exposure to
equity: Use cash + long futures (equitized cash)
The
fundamental law of active management
IR = ICsqrt(IB)
IR: Information
Ratio
IC: Information
Coefficient (knowledge of individual securities)
IB: Investor Breadth
(number of independent investment decision)
IC: measured by
comparing the forecast and outcome
Investors are more
risk averse when facing active risk than total risk:
- Need to believe there is +ve active return and
can pick the right manager for +ve active return
- Need to proof +ve alpha if really taking
active risk
- Becomes less diversified if putting most of
the money in high active return managers
Target active risk
and active return and use optimization process to find the best mix of equity
mangers. (Assume no covariance)
Core-Satellite
Approach:
Invest core portion
in passive or semiactive managers
Invest the rest
(Satellite) in different active managers
Completeness
Fund Approach
The aggregation of
several managers’ fund may not have the characteristic to match that in the
index. A completeness fund can be used to make the overall risk the same as the
benchmark
True Active Return =
return – manager’s normal return
Misfit Active Return
= manager’s normal return – benchmark return
True IR = true active
return/ true active risk
Alpha
and Beta Separation
Invest in large cap
for Beta and then avoid market risk by doing long-short in small cap for alpha.
Can change the Beta
by going to other index – portable alpha
Selecting investment
managers:
- History: consistency and good history
- Questionnaires + interview
- Staff and organization
- Investment philosophy and procedures
- Resources and research
- Performance
- Fee
Fees:
Ad valorem (according to the value): charged according to Asset Under
Management (AUM) .e.g 0.4% – straight forward, known ahead, not aligned with
investor’s interest
Performance-based
fee: base fee + alpha: aligned interest, symmetric but more complicated and
hurt organization at low time
There is fee cap and
high water mark also
Fee cap is to
prevent manager from taking too high a risk
