Wealth Matters: Making sense of the small-value stock approach to investing

Investing was less complicated for our parents: some stocks, some bonds, a savings account…

 While those vehicles still exist today, the ways to evaluate and allocate them have changed dramatically over the last few decades.  Investors have new ways to think about how and where to invest.  This year’s Nobel Prize in Economics was awarded to Eugene Fama of the University of Chicago whose theories have had tremendous influence on how we advisers gauge the market. 

 In the 1960s, Fama’s team proposed the “efficient market hypothesis” (the price of any investment reflects all available known information about it at any given time).  He shot down the idea of trading portfolios based on hunches about a specific stock’s outperformance of the general market.  The entire indexing movement (S&P 500 index funds and the like) was born of Fama’s efficient market theory; making it easier, cheaper and more effective for the average investor to invest in a diverse portfolio.

 Later, in the early 1990s, Fama and his partner, Ken French of  Dartmouth College, developed the “Three Factor Model.”  Look for these men on the short list of a future Nobel Prize Committee because the Three Factor Model is arguably the best way to determine the expected return on an investment. 

Why Small and Value Outperform

 Using the Three Factor Model and historical data, Fama and French have demonstrated the outperformance of small company stocks and value stocks (those stocks with low price to earning ratios over a general market portfolio).  The data is clear: value stocks outperformed growth stocks and small cap stocks outperformed large cap stocks. Over the last 20 years, value stocks returned annually 9.93 percent, small cap stocks returned 10.91 percent, while general large cap stocks returned just 8.23 percent.


Why is this so?  Here is an example: Sears (a large cap value stock) has struggled for years as consumers have found better places to shop online or elsewhere. While Google (a large growth stock) on the other hand has been on the forefront of technology innovation and increased sales steadily for over a decade. If these two companies went to a bank for a loan it is obvious that Google would receive a more favorable loan package than Sears. Google is simply stronger, healthier and with much better prospects for future growth. Now, if these companies went to Wall Street and "asked for a loan" by selling stock, how would an expected return or interest rate be assessed? 

 It is actually quite similar to getting a loan at the bank.   The "bank," in this case "Wall Street," determines which company is stronger financially with the best future prospects. Wall Street will determine a price for the shares of Sears and Google and Google will win, with the higher priced shares and, correspondingly, a lower expected return or interest rate for the "loan" they are taking.  If you are an investor, you want the company with the higher expected return or interest rate, so, you would actually want to invest in Sears, NOT Google.  The same principal works for small cap stocks. The banks and Wall Street both assess a financing penalty (or cost) to small companies because of their higher business and financial risk. 

Value and Small Stocks Worth the Risk?
