Practically, all information is already reflected in the stockcharts. When insiders sell or buy their companies shares, it takes 3 days before it gets reported to the SEC. Chasing after it is old news! When they release news to the retail investors and traders, the big money investors and hedge funds have long taken up positions in the stockmarket. Big money investors and hedge funds are the market. Retail investors and traders do not have enough monies to move any stock for that matter!
