The Wall Street Journal yesterday had a nice little sidebar about websites that offer free (and pay) information about insider trades. The sites are Thomson Financial and Vickers Stock Research. Insider buys are often a good indicator that a stock will go up. Insiders sells are less useful, as insiders frequently sell just to diversify their holdings, which is only prudent. Right now, I don't see any stocks with heavy insider buying that I like, but it's worth watching.
