At Stockpickr.com, we keep track of the Top 10 Insider Purchases and Buybacks each week. One of the primary goals of Stockpickr.com is to allow everyday investors to see what the big guns are buying.We often see a big-name investor loading up on a particular stock. This is usually a good sign, because you know that person put a lot of time and due diligence into that process. But then we also like to see that same company announce that an insider has purchased a large chunk of stock or, even better, that the board is planning a large buyback program. Then we have a very nice place to start our own homework.
