While there are greater than 8000 funds in operation at present, we at Insider Monkey choose to focus on the moguls of this group, around 450 funds. Most estimates calculate that this group has its hands on most of the smart money’s total asset base, and by tracking their highest performing stock picks, we have spotted a number of investment strategies that have historically beaten Mr. Market. Our small-cap hedge fund strategy beat the S&P 500 index by 18 percentage points a year for a decade in our back tests, and since we’ve started sharing our picks with our subscribers at the end of August 2012, we have outpaced the S&P 500 index by 25 percentage points in 6.5 month (see the details here).
