RenTech Funds Soar More Than 30%

It's been a banner year for Renaissance Technologies, which can boast a pair of funds up in excess of 30%.

That's par for the course for the East Setauket, N.Y.-based firm's flagship Medallion Fund, which has managed almost exclusively internal capital for a year. Medallion is up 32% this year, the New York Post reports. But just a few steps behind is RenTech's Institutional Equities Fund, which has done more disappointing than impressing since it was launched six years ago.

RIEF, which RenTech founder James Simons once dreamed of raising $100 billion for, is up 31% this year after rising almost 5% last month. The fund, which once managed as much as $28 billion, currently has $6.1 billion in assets.

A third RenTech fund, Institutional Futures, isn't doing nearly as well. That fund was up just 4.36% through September.
