"All things to all people is
an ideal that usually fails to serve the
true needs of those involved. Index investing is no exception
to
this rule." -Diane
Garnick, Global Investment Strategist, State
Street Global Advisors |
The staid world of indexing has been shaken up in the past few
years by new competition and innovations. We sat down briefly
with Diane Garnick to talk about some recent developments in passive
investing.
Garnick is the Global Investment Strategist at State Street Global
Advisors, where her primary goal is to generate new investment
strategies for the plan sponsor community. She moved to State
Street in June of 2001 from Merrill Lynch, where she was the director
of equity derivatives strategy. Garnick has published reports
that cover a wide array of investment topics and is one of the
industry's foremost experts on portfolio construction and benchmark
selection.
Q: How can existing style indexes be improved?
A: The debate over how to improve the style indexes, sometimes
referred to as growth and value indexes, continues as practitioners
and academics alike are discovering ways to expand and improve
existing theories. Three primary issues are consistently raised,
hence index providers would be well served if they focused on
these areas.
First, the factors used to classified a stock as growth or value
should be more reflective of the investment process used by asset
managers. Secondly, the transparency of the indexes must be as
clear as possible. All models used to determine a stock's classification
should be fully disclosed, with changes updated regularly. Finally,
the frequency of rebalancing the style indexes should be carefully
examined. The pace of change in the global equity markets suggests
that rebalancing on a quarterly basis would result in indexes
that more closely reflect the market. To protect investors from
excessive turnover, barriers should be created before a company
is reclassified.
Q: You seem to think some indexes are good for passive
funds, while others are better to judge active manager performance.
Are these two qualities mutually exclusive?
A: All things to all people is an ideal that usually fails
to serve the true needs of those involved. Index investing is
no exception to this rule. Passive strategies require a high level
of transparency and liquidity, and low turnover rates. Conversely,
active strategies are best served when the opportunity set of
stocks is large, providing managers with a deeper pool of stocks
to select from.
Q: Could investors benefit from hedge fund index funds
or is this an example of the industry taking the indexing concept
too far?
A: Hedge fund return data should be relied on with great
reluctance. Given the loose regulatory structure of the industry
and the innovative strategies that are created almost every day,
sufficient data is still not available to create an index that
adequately reflects the industry. Investors are still better served
by obtaining independent advice as to the risks embedded in hedge
funds prior to committing capital.
Q: Some claim that index fund managers are at a disadvantage
because their portfolios are transparent. Have index fund managers
gotten better at avoiding front-running?
A: The real question is whether the index managers have
become better at managing index changes, or if hedge funds have
become more skilled at trading index changes. I would argue that
the index change strategy that existed for so many years has dissipated
as a direct result of the market becoming more and more efficient.
We discovered, tested, and then published data and strategies
surrounding the now infamous "index effect." The spreads
that once existed in the market have tightened, reducing the opportunities
for active managers and simultaneously reducing the cost index
changes had to passive investors.
