John Montgomery is the manager of Bridgeway, a no-load mutual fund family (like Vanguard). One of their funds that is most interesting to investors (and that is still open currently for investment) is their Ultra-Small Company Market Fund (BRSIX), which is a passively-managed fund of the smallest of the small publicly traded companies. It’s benchmark index is one that you’ve probably not heard before, the CRSP Cap-Based Portfolio 10 Index, which is an unmanaged index of about 1670 smallest publicly traded stocks.
Small cap stock funds, like this one, is not for the faint of heart. Small companies are subjected to business and capital risks most large companies are not subjected to or at least to the same degree.
First there is the issue of access to capital. On whole, smaller companies have limited access to capital as compared to their larger cap cousins. Also, when it is made available, it is at a much higher cost. The reasons for this should be relatively clear. Smaller companies are subjected to much higher business risk, risks to the entire enterprise that may “take down” the whole ship. Again in relation to much larger companies, smaller companies tend to have immature product or services lines of business, less experienced management, greater costs (access to capital to grow) and a greater exposure to losses to net income from losses of primary supplier(s) and primary customer(s).
John Montgomery, in his February 25, 2008 investment management team letter stated that their examination of the data between 1926 and 2000 revealed that “ultra-small stocks fell an average of 35% more than large stocks during the average calendar year market decline” and that their “best generalized advice is not to have more in these funds than an investor means to have for the long haul, nor more than investor can afford to hold through a downturn.” He goes on to say that this generalized advice is good advice when considering one’s own stock market risk tolerance, i.e. what percentage of your total investments will be in stocks.
So why hold the stocks of small cap companies? Higher *expected* returns. Please note I did not write “higher *guaranteed* returns”. The evidence suggests that the longer the time period held, the more likely the higher expected returns of smaller cap stocks will show up. Investors in small companies demand (and historically have received) what the academics refer to as a “risk premium“, a premium for buying higher-risk investments.
Author Larry Swedroe gives an illustrative example of 2 companies: Wal-Mart and K-Mart. He asks readers to consider which is the “better” company. Most people would consider Wal-Mart the “better” company of the two. He then asks readers to consider which stock would make a better investment? Again, many would answer Wal-Mart, in large part because it is perceived as the “better” company. Mr. Swedroe’s argument is that K-Mart would likely be the better stock to own because of its risk premium. In a big picture sense, investors can allocate and deploy their capital as they see fit. They don’t *need* to invest in K-Mart. So, investors that actively choose to invest in K-Mart over Wal-Mart demand (expect) a higher rate of return over what they would get if they invested in Wal-Mart.
We can apply this example to smaller cap stocks. Investors (that can deploy their capital in any manner) that choose to invest in smaller companies demand (expect) that their investment returns in this risky asset class will be higher than large cap companies as the stock market has historically rewarded risk. If the expected returns were the same, there would be no reason for an investor to choose a riskier investment over a “safer” one!
Mr. Montgomery further noted in the investment letter cited above, “in ten of the last eleven recessions, stocks rose an average of 24% after the low”. He is referring to the average stock market gain (of all stocks). Because small cap stocks have a higher expected return, investors in small companies expect an even higher post-recession increase.
Again, not every expectation of gain materializes. If there were no risk, there would be no risk premium. But the longer the holding period time frame, the *more likely* the expected returns materialize.
