Federal Bureau of Investigation agents raided the Connecticut offices of hedge funds Diamondback Capital Management LLC and Level Global Investors LP amid a far-reaching insider-trading investigation.
"The FBI is executing court-authorized search warrants in an ongoing investigation," said Richard Kolko, an FBI spokesman, who declined to comment further.
Both hedge funds are run by former managers of Steve Cohen's SAC Capital Advisors. Level Global Investors LP is a Greenwich, Conn., hedge-fund firm run by David Ganek, a former SAC Capital trader and art collector. He started Level Global in 2003 and earlier this year reported managing about $4 billion in assets.
Diamondback Capital Management LLC is based in Stamford, Conn., and was started in 2005. It oversees more than $5 billion in assets, according to SEC filings.
The move by the FBI follows an article by The Wall Street Journal describing an insider-trading investigation that is expected to encompass consultants, investment bankers, hedge-fund and mutual-fund traders. The investigation is said by people close to the situation to eclipse in size and magnitude past insider-trading probes.
