Analyst ratings are a great guide to what the market is thinking about a company's outlook, but finding groups of analysts that have a history of predicting stock performance is even better.

When those analysts become more optimistic about a company, it's a signal to take a second look.

Using analyst ratings from Reuters that are presented on a linear scale (with 1 = "Strong Buy" and 5 = "Strong Sell"), we sliced the ratings data of stocks paying dividend yields above 1% and sustainable payout ratios below 50% 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 point for your own analysis.
