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, too late, or that we will buy at exactly the wrong time and watch our new shares fall off a cliff.

Certainly, it is a volatile time for stocks, but investors focused on building long-term wealth know that -- regardless of daily ups and downs -- this recessionary period offers one of the best chances to buy stocks on the cheap. Seasoned value investor Bill Lippman has admitted to seeing great opportunities in the market today, and even President Obama has weighed in and encouraged people to buy stocks for long-term investment.

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 reliable and relatively stable returns in large caps like Chevron (NYSE:CVX), CVS Caremark (NYSE:CVS), or Pfizer (NYSE:PFE), which are trading at values not seen in years. But if history is any lesson, you're selling yourself short precisely because this is the same, conservative approach many other investors are taking.

Looking back, many of the market's best stocks, like Hansen Natural (NASDAQ:HANS), Celgene (NASDAQ:CELG), and XTO Energy were small caps during the last recession, and have since grown into multibillion-dollar companies. You may know that small caps outperform others over the long term, but small-cap companies have also 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 stocks for 10 years between 1974 and 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, what many are trumpeting as the worst financial environment since World War II? If we look from what many are now acknowledging as the start of the recession (early December 2007) to the market bottom in March, we see that stocks -- small and large alike -- have all seen a similarly severe pounding.

Despite all the predictions flying around, no one knows if stocks have found a bottom or when the recession will end. But since the 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 does lend evidence that, once again, small-cap stocks that don't attract the same amount of attention from analysts or institutional funds tend to be more significantly mispriced. For this reason, an investor is more likely to uncover a good value on a small-cap stock with strong fundamentals and a solid balance sheet 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 that I've been looking at for their strong growth and return on equity, as well as low-to-nonexistent debt to equity ratio:
