If you plan to look through the investment positions of other known investors like Marty Whitman, Michael Price, Seth Klarman, etc., make sure you have as good an understanding or better of the particular company that you buy. Never cease to do your own work or you will neither learn nor probably profit. Mr. Mohnish of www.pabraifunds.com uses this technique shamelessly. I personally doubt that Mr. Pabrai has a solid grasp of what a franchise is by his investments in Pinnacle Airlines, Exide (XIDE), a battery company, and Lend, a subprime originator. You may be copying others who, in turn, are copying others–a reflexive circle of ignorance and sloth.
