Legendary investor Carl Icahn, known for making headlines with big moves in the market, opened a pair of major stakes in the healthcare sector during Q3.

Of late, Icahn has also been in the news for his involvement in the bankruptcy plan of troubled commercial lender CIT Group. According to Bloomberg, Icahn has said he is CIT's largest bondholder.

Looking at Icahn's top U.S.-listed, equity holdings at the end of Q3, Icahn was opening fresh stakes in pharmaceutical firms Genzyme (NASDAQ: GENZ - News) and Forest Laboratories (NYSE: FRX - News). He was also upping his stake in film company Lions Gate Entertainment (NYSE: LGF - News), which has cut costs and executive bonuses in response to prodding by Icahn.

Elsewhere, Icahn trimmed his stake in Yahoo (NASDAQ: YHOO - News), where he sits on the board of directors and played a visible role in the sage leading up to the Internet giant finally consummating a search deal with Microsoft (NASDAQ: MSFT - News).

Icahn left unchanged large stakes in Motorola (NYSE: MOT - News), video game maker Take-Two Interactive Software (NASDAQ: TTWO - News), railcar maker American Railcar Industries (NASDAQ: ARII - News), and biotechs Amylin Pharmaceuticals (NASDAQ: AMLN - News), Exelixis (NASDAQ: EXEL - News) and Biogen Idec (NASDAQ: BIIB - News), among others.

Pro portfolio performance is based on institutions' top-15 holdings as disclosed in quarter-end filings with the SEC. Pro performance does not take into account additional holdings beyond the top 15 nor does it include positions that are not required to be disclosed by the SEC. As such, Pro portfolio performance should be considered an approximation and not a precise record of how an institution has performed over time.
