Why track insiders?

Insider behavior matters because research based on real-time signals has shown that a properly modeled picture of insider actions can provide the most accurate reflection of the prospects for the company, industry, economic sector, or even the stock market in general, going forward.

This makes perfect sense from an intuitive perspective. Corporate insiders possess all the necessary skills and characteristics that one could use to describe the "successful" investor. These include: A deep knowledge and understanding of the company and/or industry; A demonstrated ability to produce success; The training necessary to understand risk and to control it; The wherewithal (capital) to take advantage of opportunity when it presents itself and finally; A tendency to go against the crowd.

Further, insider buys are especially useful. Since insiders have exclusive information on the company performance, if they are risking their own money on the stock, usually they should have good reasons, especially when several insiders buy the stock at the same time.
