Hedge Funds Made A Bundle On RIMM Today

Research in Motion Limited (RIMM) swelled amongst rumors that Vodafone Group Plc (VOD) may attempt to buy the BlackBerry manufacturer. The stock rose 12.33% on Wednesday, October 5, 2011, from a closing price of around $21 at end of day on Tuesday, October 4 to a close of $23.81 on October 5. The stock peaked at $24.34, sometime around high noon. RIMM had fallen to $20.30 a share at the end of September.

Some analysts say that Vodafone would be a poor fit for RIMM, citing instead the lackluster debut of the Apple iPhone 4S. Whatever the case, there are several hedge funds that made a bundle on RIMM today:

Jim Simons – Renaissance Technologies: Gained $7 million

Brett Barakett – Tremblant Capital: Gained $5.25 million

Jonathon Jacobson – Highfields Capital Management: Gained $4 million

Ken Griffin – Citadel Investment Group: Gained $3.3 million

John Kleinheinz – Kleinheinz Capital Partners: Gained $2.7 million
