It’s more than JPMorgan Chase & Co. paid all 56,000 of its investment bank employees, and almost twice as much as gamblers lost in Las Vegas last year. Five of them—Chris Hohn, Jim Simons, Ken Griffin, Steve Cohen and Chase Coleman—reaped more than $1 billion each, according to estimates by the Bloomberg Billionaires Index. The rewards for the men—and they’re all men—are notable, especially given only a third of the 15 managers on the list beat the S&P 500 Index’s 29% gain last year. It also comes as the hedge fund industry has been grappling with closures and mediocre returns.
