Seems like it's always the large-cap companies getting all the buzz -- it's always the big businesses like Apple and Google the making all the headlines. But for all the hype surrounding these behemoths, they're consistently bested by their small-cap counterparts on the stock market.

It's tough to say why small caps have a history of outperforming large-cap stocks. Obviously they're riskier -- so they need to generate higher returns to compensate investors for that added risk.

But there could also be some merit to the theory that an undervalued stock has a smaller market cap than would otherwise be the case, and also has a lower price-to-book ratio, putting it closer to the value end of the growth-value spectrum.

But at any rate, the results don't lie: Joel Greenblatt's "Magic Formula Investing" strategy, consistently outperforming the market year after year, arguably gets its voodoo from the inclusion of small caps. Plus, there's greater potential for rapid growth with small-cap companies. And since institutional investors are often prohibited from buying large portions of their outstanding shares, small caps offer individuals the opportunity to outsmart the smart money.

We thought this would make a great universe to start from for today's screen and wondered, which small caps have seen insider buying over the past weeks? We figure, company management knows these businesses better than anyone -- so it's not a bad idea to put stock in their trades, so to speak.
