Quantellect scores every rating on real prices. We enter at the closing price on or after the call date, with no look-ahead, then measure the 12-month return above the stock's sector ETF and check whether the price target was reached. Scores are pulled toward the population average and corrected for testing thousands of analysts at once, so they reflect repeatable skill rather than luck.

David Nierengarten ranks number 115 of 388 by Q Score. We rank analysts by their realized 12-month sector-excess return and require a minimum number of calls so a few lucky picks cannot reach the top.
