If you’d ask most investors, hedge funds are seen as worthless, outdated investment vehicles of years past. While there are over 8000 funds in operation at present, we at Insider Monkey hone in on the upper echelon of this group, about 450 funds. Most estimates calculate that this group has its hands on the lion’s share of the hedge fund industry’s total asset base, and by tracking their top equity investments, we have found a number of investment strategies that have historically outperformed the broader indices. Our small-cap hedge fund strategy outperformed the S&P 500 index by 18 percentage points per annum for a decade in our back tests, and since we’ve began to sharing our picks with our subscribers at the end of August 2012, we have topped the S&P 500 index by 24 percentage points in 7 months (see the details here).


Equally as key, positive insider trading activity is another way to parse down the stock market universe. As the old adage goes: there are many incentives for a corporate insider to sell shares of his or her company, but just one, very simple reason why they would buy. Many empirical studies have demonstrated the valuable potential of this tactic if investors understand what to do (learn more here).
