Hedge funds rebounded nicely from the summer of subprime in September, posting one of their best months in a decade.

Following last month’s big losses, hedge funds rose 3.27% last month, according to HedgeFund.net’s HFN Hedge Fund Aggregate Index. It was the largest monthly increase in four years, and the second largest in eight. The index is now up 9.4% YTD.

What’s more, the gains were broad-based, with just one strategy—short-bias (down 2.45% in September, down 1.43% year-to-date)—in negative territory for the month. In fact, strategies hardest hit in August performed the best in September.

CTA/managed futures funds rebounded nicely, leading the way with a 6.15% return (up 7.11% YTD). Energy sector and emerging markets funds rose 4.99% (13.95% YTD) and 4.6% (16.79% YTD), respectively. Long-only and long/short equity funds enjoyed the month as well, adding 3.15% (10.55% YTD) and 2.98% (10.66%).

On the other hand, distressed managers rose just 0.57% last month, but are still down 2.06% year-to-date.

Regionally, Latin America funds remained the top-performing strategy overall, adding 3.83% last month to reach 20.81% year-to-date. Asian funds added 4.33% and are up 14.84% year-to-date.
