Galleon's Biotech Stock Holdings: BioBuzz

NEW YORK, NY (TheStreet) -- Galleon Group may be forced to sell its extensive biotech holdings as investors in the hedge fund seek to pull out their money following the arrest this week of founder Raj Rajaratnam on charges of alleged insider trading.

Galleon owns a long list of biotech stocks, but many of the fund's positions aren't particularly large, according to the fund's 13-F for the September quarter, filed with the Securities and Exchange Commission. Some of its holdings are in highly liquid stocks, so any selling that might occur could be easily sopped up by the market.

OSI Pharmaceuticals(OSIP Quote), OncoGenex Pharmaceuticals(OGXI Quote), Medivation(MDVN Quote), Orexigen Therapeutics(OREX Quote) and Biogen Idec(BIIB Quote) are among the larger biotech stock positions held by Galleon, according to its SEC filing.

The fund holds numerous other smaller biotech holdings, including Acorda Therapeutics(ACOR Quote), Dendreon(DNDN Quote), Rigel Pharmaceuticals(RIGL Quote), Optimer Pharmaceuticals(OPTR Quote), Amylin Pharmaceuticals(AMLN Quote) and Alexion Pharmaceuticals(ALXN Quote).

The biotech sector is underperforming the market today, with Galleon holding Oncogenex down 8%. But then, Medivation, another of the fund's holdings, is up 2% today.
