For many investors, picking the precise time to buy a stock is one of the most anguishing aspects of investing. Too often, we're plagued with fear that we're too early -- or too late.

Certainly this is (still) a volatile time for stocks, but investors focused on building long-term wealth know that this volatile period offers one of the best chances to buy overlooked and undervalued stocks. Even the world's largest bond fund manager, Bill Gross of Pacific Investment Management Co., sees opportunity in stocks as a long-term investment. The company, which he founded, recently announced it would offer stock funds for the first time.

OK, I'll buy. But which ones?
If you're like many other investors looking to buy a cheap stock today, you're probably tempted by large caps like Coca-Cola (NYSE: KO), Corning (NYSE: GLW), or Johnson & Johnson (NYSE: JNJ), which are trading below highs seen in recent years. But if history is any lesson, you're selling yourself short -- precisely because this is the same conservative approach that many other investors are taking.

Looking back, many of the market's best performers since the previous recession -- like Goldcorp (NYSE: GG) and (Nasdaq: PCLN) -- were small companies before their big runs began. You may know that small caps outperform others over the long term, but small-cap companies have also handily beaten large caps in the year following the past 10 recessions.                                          

For instance, Money magazine points out that after the 1973-74 downturn, small caps beat large-cap stocks for 10 years from 1974 to 1983. And after the Great Depression, small stocks led the market for 11 of the next 13 years.

Yeah, but this time could be different
So how is the "small caps outperform everything" theory holding up in this recession? If we look from what many are now acknowledging as the start of the recession (early December 2007) to the market bottom in March 2009, we see that stocks -- small and large alike -- took a severe pounding.

Despite all of the predictions flying around, no one knows whether March 2009 will turn out to have been the bottom. But since that March low, small caps have once again bolted out of the gate.

This is only a small window to compare performance, of course, but the data do lend evidence that, once again, small-cap stocks tend to be more significantly underpriced. For this reason, an investor is more likely to uncover a good value on a small-cap stock with strong fundamentals before the mainstream market catches on.

And don't get too caught up in timing the end of the recession. According to State Street Global Advisors, in the three years following the midpoint of each of the last three recessions, small-cap stocks delivered a solid advantage, particularly relative to large caps, returning an annual average of 8% more than large-cap stocks.

Many places to start
Here are some small caps I've been looking at for their strong growth and return on equity, as well as low to nonexistent debt-to-equity ratio:
