King Ken: Recovered Citadel chief takes the hedge fund throne

Ken Griffin's rise to power

In April, a hedge fund firm in Chicago snagged arguably the most sought after economic mind in the world: Ben Bernanke.

"He has extraordinary knowledge of the global economy," Citadel founder and CEO Ken Griffin crowed in a statement announcing that his investment shop had hired the former Federal Reserve chairman as a senior advisor. "His insights on monetary policy and the capital markets will be extremely valuable to our team and to our investors."

Bernanke's role at Citadel is part time, given his other duties as a Brookings Institution fellow and advisor to Pimco, the fund giant. But the symbolism of the estimated $1 million hire was clear: Citadel is once again a dominant force in the investment industry.
