How does Quantellect score analyst accuracy?

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.

How does Daina Graybosch rank among Wall Street analysts?

Daina Graybosch ranks number 304 of 458 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.

Every score, Win %, PT Hit % and rank is an estimate Quantellect calculates from its own data and may not be 100% accurate or complete. Returns are measured in excess of each rated stock's own sector over the 12 months after each call. Past performance does not guarantee future results, and nothing here is a recommendation to buy or sell any security.
