5 Insider Stock Picks that Predictive Analysts Expect to Outperform

Analyst ratings are a great way to gauge what the market currently thinks about a stock's outlook -- if you're considering the stock for purchase, knowing whether you're going with or against other investors is an important starting point.

But this starting point can be improved. Groups of analysts whose ratings have historically predicted stock movements are theoretically more likely to predict future movements. Looking for these "predictive analysts," we compiled analyst ratings from Reuters to find groups of analysts that have rightfully predicted stock market movements over the last three months.

The screen
Beginning with companies that have seen significant net insider buying over the last six months, we screened these stocks for those being followed by groups of predictive analysts.

From Reuters ratings presented on a linear scale (with 1 = "Strong Buy" and 5 = "Strong Sell"), we sliced the data of stocks seeing significant net buying from insiders into three monthly time periods and identified the groups of analysts that have shown predictive value over two consecutive time periods.

We further narrowed down the list by only focusing on those stocks that have seen bullish trends in recent analyst opinion.

Although past performance is no guarantee of future results, the recent accuracy of these analyst ratings suggests their opinions may be a helpful starting-off point for your own analysis.

Insiders are buying these stocks while predictive analysts expect them to outperform -- do you think these stocks are in a strong position to move higher?
