How accurate are Jason Zemansky's stock ratings?
Based on the calls 13Foresight could measure, about 49% of Jason's ratings were profitable over a one-year hold, with an average return of +5.8% per rating, or +3.1% versus the S&P 500. We score every analyst the same way, from historical prices. Each return is measured in the stock's own trading currency, so for non-US listings the S&P 500 comparison leaves out currency moves.

Jason Zemansky is currently ranked #1372 with a 3-star rating. Our rank blends hit rate, average return versus the market, and how many calls we have to judge — so a long, consistent record outweighs a few lucky picks. It is our own calculation, updated daily.
