In a victory for common sense, it has been proven profitable—by both academic studies and (more importantly) the experience of your fellow professional investors—to monitor the trading behavior of company executives, directors, and large shareholders in the stocks of firms of which they're registered as "insiders."

Please note, however, that the lists above are strictly factual; they are not buy and sell recommendations. Dollar value is only one metric to assess the importance of an insider transaction, and, frankly, often not even the most important metric that determines if an insider transaction is significant.

At InsiderInsights.com, we find new investment ideas just about every day using these and more intricate insider screens to determine where we should focus our subsequent fundamental and technical analysis. And while stocks don't (or shouldn't) move up or down based on insider activity alone, insiders tend to be good indicators of when real stock-moving events like earnings surprises, corporate actions, and new products may be in the offing.
