Micro-cap ETF soon?

Morgan Stanely Capital International (NYSE:MSCI) is about to unveil a new micro-cap index on Monday, according to Barrons. Wilshire already offers a U.S micro-cap index, but MSCI will use a different methodology.

Now, the publication of a new index and its underlying methodology are not generally topics that will excite most investors. But this is different and important. Here's why.

MSCI has focused on producing indices that are easier to use as investable products, for example by adopting available-float weighting instead of market-cap weighting and by implementing ways to reduce the turnover of index constituents. As a result, Vanguard, for example, has begun to adopt MSCI float-weighted indices.

This could mean that a micro-cap index exchange-traded fund (ETF) is not far off. Currently, there are hardly any micro-cap index mutual funds. Dimensional Fund Advisors (DFA) offers an index fund, but it's not directly available to retail investors, and hedge fund managers can't short it. Vanguard has no micro-cap index fund. And critically, there's no micro-cap ETF.

Why is the availability of a micro-cap ETF so important? Because both asset allocators and long-short hedge fund managers would benefit enormously from its availability. Asset allocators need a micro-cap ETF because micro cap stocks are a distinct asset class from small caps, with totally different performance. For example, the Wilshire Micro Cap Index has gained an average of 17% over the last ten years, versus 11% for the Wilshire Small Cap 1750 index.

Hedge fund managers also need a micro-cap ETF for two reasons. First, many hedge funds look to small stocks for alpha generating opportunities, on the assumption that the market for small cap and micro cap stocks is less efficient and therefore rewards managers with an information advantage. But small cap and micro cap stocks are hard to short. This means that many long-short hedge funds suffer from intrinsic market cap bias: long small and micro caps, short large caps. That net long-bias to small and micro caps is fine when small and micro-caps outperform large caps, but is lousy when the reverse is true. The availability of a liquid micro-cap ETF would solve this problem for many managers, as they could hedge their long positions in individual micro-cap stocks with a short position in the micro-cap ETF.

Second, many fund managers use ETFs to play momentum in asset classes. The more volatile an asset class, the greater the opportunities (and risks). That's one of the reasons why SMHs (Semiconductor HOLDRs) are so popular with hedge fund managers: they're about the most volatile of all the U.S equity ETFs. But now look at the performance of micro-caps. The Wilshire micro-cap index was up 92% in 2003. In 2004, it was up another 8.7% in Q1, down 3% in Q2, and down another 5.2% in Q3. Hedge fund managers would love an easy way to access that volatility.

The full Barrons article about MSCI's push into the competitive world of U.S indexing is here (paid subscription required). It does a good job of outlining MSCI's methodology and marketing push, but fails to note the dearth of micro-cap indexes and index funds and why that might be.

By focusing its discussion on large cap indexes and index funds, Barrons joins the rest of the ETF industry in focusing on asset classes that are already available to investors, and fails to focus on asset classes that still lack investable indices. That criticism was one of points made in Why exchange-traded funds could alter the investment landscape.
