During the speculative bubble of 1999, investors began to believe
that diversification was merely a way of reducing returns. The bear
market of 2000 has brought a welcome return to reality. As a result,
investors are looking for additional ways to increase diversification
while maintaining market exposure. Total return investing (often
referred to as hedge funds) has become one such alternative though
they are difficult to analyze in traditional ways. While often viewed
as presenting new problems to fund sponsors and consultants, total
return investing is really a return to the period before Modern
Portfolio Theory (MPT), and Markowitz mean/variance efficiency became
the standard.
Defining hedge funds is problematic by itself. Essentially there
are no rules in total return investing. Strategies that are considered
imprudent by institutional investors are considered standard and
essential in hedge funds. These include using leverage and shorting
securities. But the strategies are attractive. They offer high returns,
low volatility and excellent diversification with traditional investment
styles.
However, there are many methodological and cultural problems for
institutional investors. Methodological problems are concerned with
investment methods that, in isolation are considered imprudent,
though used together actually reduce risk. Because of their nature,
using mean/variance analysis to position such strategies in a fund
may not apply.
There are no benchmarks for the strategies since they are based
upon achieving high total returns. Cultural problems come from the
fact that the hedge fund industry is largely unregulated and used
to dealing with wealthy individuals who are responsible only for
themselves, not for other people's money. There is little client
service. Hedge fund managers are notoriously secretive about their
investment process--making it difficult to perform due diligence
analysis.
For these reasons (especially the problem of benchmarking), conducting
a strategic asset allocation using hedge funds is problematic. Many
have advocated avoiding total return investing for this reason.
ASSET ALLOCATION
It is important to remember that there was a time before MPT, when
all investing was considered total return investing. MPT and the
Capital Asset Pricing Model (CAPM) brought us the concept of benchmarking,
which simplified performance measurement as well as strategic asset
allocation. Prior to CAPM, strategic allocation was largely done
by intuition--looking at the individual managers in the fund. Benchmarking
allowed us to simplify the asset allocation process. We could now
use the benchmark for stocks and bonds, or other asset classes,
and feed them into a mean/variance optimizer as proxies for the
underlying managers.
Unfortunately, hedge funds do not lend themselves to this convenient
shortcut.
Both institutions and hedge funds must adapt if institutional investors
are to benefit from this attractive style of management.
For institutions and consultants, it means a return to full mean/covariance
analysis of the fund using candidate hedge fund managers themselves
rather than a market proxy. This means additional work, but no one
said that long-term investing was easy. Funds will have to screen
managers and then perform a full analysis to decide how much will
be appropriate for investment.
Hedge fund managers will have to supply more transparency and client
service. A statement of investment policy stating the amount of
leverage which can be used, general guidelines used for shorting
stocks and overall portfolio characteristics must be supplied to
clients in order for them to perform their fiduciary responsibilities.
Finally, long-run risk/return targets should be given as total return
goals.
With these adjustments, a new diversifying style, which offers
high returns, would become available to institutional investors.
