Gartner Inc. (IT), Signet Jewelers (SIG), and WPX Energy (WPG) Among the Companies Reporting Notable Insider Trading Activity

While Securities and Exchange Commission rules require executives, directors and other insiders to report purchases or sales in their own company’s stock within two days, an accurate interpretation of insider trading data has become more complicated in recent years. That’s because of the increased usage of equity-based compensation, as well as the proliferation of pre-arranged trading plans. As more directors and executives sell shares under the so-called 10b5-1 plans, it is close to impossible to figure out the reasoning behind their moves, while stock-based compensation packages make it even harder to find out why corporate insiders might be selling shares. Meanwhile, insider buying activity has become more useful than ever, but one should still keep in mind that corporate insiders are susceptible to biases and errors like any other human being. However, they are in the best position to accurately evaluate the prospects and current conditions of their companies, which is why Insider Monkey keeps track of their moves on a daily basis. Our team processed the Form 4 filings submitted with the SEC on Wednesday and identified five companies with noteworthy insider trading transactions.

Academic research has shown that certain insider purchases historically outperformed the market by an average of seven percentage points per year. This effect is more pronounced in small-cap stocks. Another exception is the small-cap stock picks of hedge funds. Our research has shown that imitating the 15 most popular small-cap stocks among hedge funds outperformed the market by nearly a percentage point per month between 1999 and 2012 (read more details here).
