Rambus Inc. (NASDAQ:RMBS) investors should pay attention to a decrease in enthusiasm from smart money recently.

In the eyes of most investors, hedge funds are seen as unimportant, outdated financial vehicles of yesteryear. While there are greater than 8000 funds in operation at present, we at Insider Monkey hone in on the aristocrats of this club, about 450 funds. Most estimates calculate that this group has its hands on the lion’s share of all hedge funds’ total capital, and by keeping an eye on their top investments, we have determined a number of investment strategies that have historically beaten the S&P 500 index. Our small-cap hedge fund strategy outpaced the S&P 500 index by 18 percentage points per 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 trumped the S&P 500 index by 24 percentage points in 7 months (explore the details and some picks here).

Just as integral, positive insider trading activity is a second way to break down the marketplace. Obviously, there are a number of motivations for an upper level exec to sell shares of his or her company, but only one, very clear reason why they would behave bullishly. Many academic studies have demonstrated the valuable potential of this tactic if piggybackers know what to do (learn more here).
