From our earnings database, below we highlight the Russell 3,000 stocks that have averaged the biggest gains on their earnings report days over the last ten years. As shown, Intuitive Surgical (NASDAQ:ISRG) and Hanger Orthopedic (HGR) have been earnings season champions, both averaging gains of more than 8% on their report days. Not far behind are First Solar (NASDAQ:FSLR), Radian Group (NYSE:RDN), and Healthways (NASDAQ:HWAY). Also included on the list of earnings season winners are ITT Education (NYSE:ESI) and Mastercard (NYSE:MA). Obviously, just because a stock has historically gone up on earnings doesn't mean it will do it this quarter, but we think there is something to be said for consistency.
