Bill Ackman may be a relative newcomer to the hedge fund game, but that doesn't mean he's going to shy away from controversy.
Both Ackman's failures and successes have been spectacular. On the one hand, his fund Pershing Square Capital Management held a sizable stake in the now-bankrupt Borders Group, and it's currently the largest stakeholder in J.C. Penney (NYSE: JCP ) , which could easily follow Borders' lead. But on the other, to name only two of his more notable successes, he made a killing shorting subprime mortgage bond insurer MBIA (NYSE: MBI ) in the lead-up to the financial crisis, and he's purportedly sitting on a substantial unrealized profit from his short position on Herbalife (NYSE: HLF ) .
Love him or hate him, as activist investor Carl Icahn does, there's no getting around Ackman's prowess in the hedge fund world. With this in mind, I thought it'd be interesting to uncover his fund's 10 largest stock holdings (according to its most recent 13F), which are presented in the chart below, along with a breakdown of Pershing Square's holdings by sector (and a video of Icahn and Ackman going at it live on CNBC).
