One of the primary goals of Stockpickr.com is to allow everyday investors to see what the big guns are buying. Often times, we 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. Plus, high-profile investors have bankers, lawyers and consultants breaking down the business every which way imaginable.

The real icing on the cake, however, is when that same company announces that an insider has purchased a large chunk of stock or even better, the board initiates a new, large share-buyback program.

That's why each Thursday at Stockpickr we update the Top 10 Insider Purchases and Buybacks portfolio, featuring the stocks that in the last week had either big insider purchases or newly announced buybacks, as well as super-investors accumulating shares. This week's portfolio includes AK Steel ( AKS) and Teekay ( TK).
