Analyzing Friday's Noteworthy Insider Buys And Sells
20.05.12
: Insider trading as defined here (and by the SEC) includes not just corporate insiders such as company executives and key employees, but also directors and large shareholders that have access to non-public information. Large shareholders are defined by the SEC for this purpose are those that having beneficial ownership of ten percent of more of the firm's equity securities (including institutional investors). Also, in the U.S., "insiders" are not just limited to corporate officials and major shareholders, but also when a corporate insider "tips" a friend about material non-public information, the duty the corporate insider owes the company is now imputed to the friend who is now in violation of a duty to the company if he or she trades on the basis of that information. The U.S. is generally viewed as having the strictest laws against illegal insider trading, and makes the most serious efforts to enforce them.
While most insider trading is legal, the term is commonly used to refer to the illegal kind when a corporate insider trades based on material non-public information that can have an effect on the company's share price. By law, insiders are prohibited from trading based on nonpublic information, but most believe that such trading does occur around the edges. The thinking goes that corporate insiders, because of their access, have the most up-to-date information on the health of their companies and the industries they operate in. Investors, as a result, can benefit from the timely knowledge of insider transactions. In fact, one University of Michigan study found that when executives bought shares in their own companies, the stocks tended to outperform the total market by 8.9% over the next 12 months. Conversely, when they sold shares, the stock underperformed by 5.4%.
