Hedge fund update: Tudor Investment Corp.

Another in a series of updates on Boston hedge fund holdings based on quarterly reports filed with the Securities and Exchange Commission this week:

Tudor Investment Management is a large hedge fund firm, headquartered in Greenwich, Conn., that manages many investment products. Some of them, including the well-known Raptor fund, are managed by Jim Pallotta from Boston, but Tudor lumps all its reportable holdings into one SEC filing. That filing reports stock and some equity derivatives, but not other kinds of investments.

The 10 largest investments reported by Tudor, as of June 30, were:

Kraft Foods Inc. ($989 million), Motorola Inc. ($598 million), Mirant Corp. ($402 million), Altria Group Inc. ($374 million), and Prudential Financial Inc. ($352 million).

Also, CVS Caremark Corp. ($348 million), TD Ameritrade Holding Corp. ($314 million), Virgin Media Inc. ($286 million), NRG Energy Inc. ($286 million), and Thermo Fisher Scientific Inc. ($285 million).

Tudor’s top 10 stock investments on March 31 were:

Motorola, CVS, Altria, Tyco International Ltd., Williams Cos., Mirant, Prudential, Sears Holdings Corp., Virgin Media and Qwest Communications International.
