JAMES SIMONS
Renaissance Technologies Corp.
$1.7 BILLION
EVEN THE MOST SUCCESSFUL hedge fund managers have to shake their heads in wonderment at the extraordinary continued success of Renaissance Technologies Corp. founder James Simons. Last year his $6 billion Medallion fund posted a 44 percent return after fees, easily exceeding its roughly 36 percent average annualized net return since he launched the quant-based fund in 1988.
