Ackman is known for running a pretty concentrated portfolio, compared to other large hedge funds that sometimes own 100's of stocks.
Note: This should not be considered a comprehensive list because Ackman often uses total return swaps and other derivatives that would not show up on a 13F filing. Also this does not include his short positions, warrants, etc.
Here is Pershing Square Capital Management's top 10 long positions:
Data current as of 11/15/2010 and is updated to reflect Ackman's new ownership statement regarding General Growth Properties and Howard Hughes Corp.

Ackman is probably one of the best investors when it comes to commercial real estate. Case in point: General Growth was considered worthless in late 2008, just when Ackman was buying the stock. It turned out to be a huge home run for his investors. Other notable holdings include JC Penny because of its large real estate holdings, no doubt. The idea is to force JC Penny to implement a sale/leaseback transaction to generate cash and buyback stock. Fortune Brands is a relatively new investment for Ackman and he is agitating for a break-up of the company to unlock shareholder value.
