Optimer Pharmaceuticals, Inc. (NASDAQ:OPTR)

To most market participants, hedge funds are assumed to be slow, old financial vehicles of the past. While there are greater than 8000 funds in operation at present, we choose to focus on the aristocrats of this group, around 450 funds. It is widely believed that this group oversees the lion’s share of all hedge funds’ total asset base, and by monitoring their highest performing equity investments, we have determined a few investment strategies that have historically outpaced the S&P 500 index. 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 started 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 all of our picks from August).

Equally as important, positive insider trading sentiment is a second way to parse down the world of equities. As the old adage goes: there are a number of incentives for an upper level exec to sell shares of his or her company, but only one, very simple reason why they would initiate a purchase. Plenty of academic studies have demonstrated the valuable potential of this method if piggybackers know where to look (learn more here).
