We've noted that several big name hedge funds managers have taken some lumps this year. David Einhorn and John Paulson top the list. But there's one star manager--or rather ex-manager--who is having a banner year.

Renaissance Technologies has staged a remarkable comeback in 2011. After posting some eye-catching losses in 2007-2009, it rallied last year and has managed to build on those gains this year. The $6 billion Renaissance Institutional Equities Fund is up 21 percent through June (not including fees), according to the New York Times. The run-up is newsworthy in part because it at least partly answers the questions about how the fund firm would fare after founder James Simons stepped down.

It is obviously faring well in spots. But not all funds at Renaissance are faring as well. The $3 billion Renaissance Institutional Futures Fund, which trades futures contracts, is down 2 percent on the year, according to the Times. I'm not sure this is enough to pronounce that quant funds are back, but it does show as always there will be winners and losers.
