For better or worse, hedge fund returns have a tendency to follow markets, in part because most long-short funds are net long most of the time.
So after a huge rebound in the stockmarket this year, which has helped hedge funds make up some much-needed ground, October proved a difficult month when the market fell in the second half of the month.
After all 2009's growing optimism, investors were suddenly concerned that a withdrawal of government stimulus would harm an economic recovery in its early stages.
So, after a bumper 2008 and a miserable 2009 for short-sellers, it was they who leaped to the fore again in October - dedicated short bias returned 1.61 percent, while long-bias funds lost 0.38 percent and long-short funds were flat.
However, the long bet may not be over for hedge funds. John Paulson, the man who made billions betting on the subprime crisis and profited last year from shorting banks, is going long Cadbury.
