In "70 Times Better Than the Next Microsoft," my colleague Bill Barker revealed which category of stocks outperformed from 1927 to 2005. Given the insane market volatility we've experienced recently, I've updated Bill's numbers through the end of 2008 to see what critical lessons we can draw. Here, then, are the returns for four categories of stocks from 1927-2008:




Large Cap



Small Cap

This data comes from highly respected scholars Fama and French, and it has powerful implications for investors.

It shows that over an 81-year period -- hardly a small sample size -- value stocks outperformed growth stocks, and small stocks outperformed large stocks. The best-performing category was small-cap value stocks, by a wide margin.

How wide?
They may look like small percentage differences, but with compounding, those small percentages add up to mind-boggling amounts of money. Here's how much $100 invested in 1927 in each of these categories, and rebalanced annually, would be worth today:




Large Cap



Small Cap



In other words, after 81 years, investing in small-cap value stocks would have yielded anywhere from seven to 31 times as much money as any of the other categories!

A big reason for small-cap value's dramatic outperformance is Wall Street's constant obsession with large, prominent firms. When hunting for bargains, investors should keep in mind that more prominent stocks are far less likely to be mispriced than more obscure small caps. You see this most clearly in companies such as Bristol-Meyer Squibb (NYSE: BMY) and Consolidated Edison (NYSE: ED), which are each covered by more than 15 analysts. These are two very strong companies that nevertheless -- based on their present earnings, cash flow, and growth prospects -- appear to me to be about fairly valued.

It's no accident, after all, that every one of the market's 10 best-performing stocks of the past decade was a small cap.

And when you combine a group of stocks that tends to be mispriced (small caps) with a group of stocks trading at low valuations (value), you're likely to find some great bargains.

Here's why
When a closely watched company appears cheap, there's often a good reason for it. That's why, in a column in September 2008, "Don't Touch These 3 Huge Value Traps," I warned investors to stay away from Citigroup, Lehman Brothers, and Wachovia.

Even though they were trading at or well below book value, these were closely followed institutions, dealing with continuing writedowns, managerial missteps, and deteriorating businesses. With so much interest in their condition from Wall Street hotshots -- each had more than 15 analysts following it -- it seemed likely that their share price declines were justified.

That may not be the case for small caps. In fact, research cited in The Wall Street Journal, along with my own findings, shows that small caps tend to outperform when the market rebounds.

Why? Because small value stocks are less closely followed by professionals, they are more likely to be mispriced. So when times are tough -- as they've been since late 2007 -- that mispricing means that small caps are punished beyond justification.

What to look for today
This isn't to say that small stocks are low-risk. Indeed, if this market has taught us anything, it's that every stock has risk. But the data does indicate that size itself isn't a great measure of safety.

From the start of this recession until the March 2009 market bottom, the small-cap tracking Russell 2000 index was basically in line with the S&P 500, and it has rebounded more rapidly.

And when we examine names such as Bank of America (NYSE: BAC), Citigroup (NYSE: C), and the assets formerly known as Lehman Brothers, we see that risk has less to do with whether a company is large or small, and a whole lot more to do with heavy debt levels, shoddy executive compensation structures, unwieldy and arcane business units, and/or unprofitability. Both companies have taken steps to reduce their leverage, though much of the same leadership and cultures are in place that led to their risk-taking, near-collapses, and eventual bailouts.

In light of these facts, investors should consider buying companies with:

  • Little or no debt
  • Heavy insider ownership
  • High profitability

In fact, these are all qualities that Warren Buffett says he seeks. So, taking the lessons from the Fama and French data, and with a debt of gratitude to Buffett, I've selected three small-cap value stocks that share those qualities. Each also has below-market-average price-to-book value multiples -- Fama and French's value metric:


Market Capitalization

Price-to-Book Ratio

Debt / Equity

Insider Ownership

Return on Equity

Atwood Oceanics (NYSE: ATW)






Harbin Electric (Nasdaq: HRBN)






Volcom (Nasdaq: VLCM)

Of course, these three bargain stocks aren't official recommendations, but they share many qualities that make for great investments, and they're excellent starting points for further research. Moreover, they hail from the small-cap value quadrant, the category that has outperformed them all.

Some more ideas
More than eight decades of historical data confirm that small-cap value stocks tend to outperform over the long haul. Research also shows that if you're going to look for great small-cap stocks, now is a particularly great time to begin bargain-hunting.
