In "These Stocks Will Burn You," I cautioned against getting too excited about the potential for making millions in small-cap stocks. Not because the chance for huge gains isn't there with small companies; I could give you any number of examples similar to E*Trade's
No, my warning was simply to let you know that with such high potential reward comes high risk. It's one of the laws of investing, and one we teach about constantly in our Motley Fool Hidden Gems small-cap investing service. You need to do all you can to avoid having a stock or two inflict years' worth of damage on your portfolio.
So how can we Fools reduce the risk involved while still keeping the potential reward high enough? Two things. First, pay attention to the balance sheet, and stay away from companies that are overleveraged with debt and burning through lots of cash. In my original article, I recommended sticking with profitable companies with cash-to-debt ratios of at least 1.5. Second, buy two, three, or even more of these small fries with the same amount of cash you'd normally allocate to one position. If $6,000 is all you're comfortable allocating to a "normal" stock purchase, try buying three small caps you like at $2,000 apiece. That way, if one crashes to earth and loses half its value, your portfolio won't be overly harmed by it.
A good example comes from the small caps I've bought in the past several months from Tom Gardner's recommendations in Hidden Gems. I now own Buffalo Wild Wings
Of course, larger companies can be volatile and burn you as well: Supposed "sure things" like JDSU
