More than 2,500 companies have reported their quarterly numbers since earnings season began in early July.  We maintain a large database of every single earnings report throughout the season, and one of the things we track is price performance on the day that a stock reports.  (For stocks that report before the open, we look at that day’s change.  For stocks that report after the close, we look at the next day’s change.)

Below is a list of the 40 stocks that have seen the biggest gains on their earnings reaction days this season.  As shown, StanCorp (SFG) has been the biggest winner with a one-day gain of 47.9%, followed by LendingTree (TREE) with a gain of 42.3%!  Three other stocks have gained more than 30% — EGL, FTK and USNA.  Other notables on the list include Wayfair (W), Nutrisystem (NTRI), Netflix (NFLX), SanDisk (SNDK), World Wrestling Entertainment (WWE) and Herbalife (HLF).

You’ll notice above that Netflix (NFLX) is the best performing S&P 500 stock with a gain of 18%.  Below is a list of the 40 best performing S&P 500 stocks on earnings this season.  SanDisk (SNDK) ranks second after NFLX with a one-day gain of 17.57%.  First Solar (FSLR) ranks third at 16.67%, followed by Google (GOOGL) at 16.05% and Expedia (EXPE) at 12.85%.  Only nine stocks in the S&P 500 have posted gains of more than 10% on their earnings reaction days.  Amazon (AMZN) was just under the 10% mark at 9.8%.  Other notables on the list of S&P 500 winners include Intuitive Surgical (ISRG), Wynn Resorts (WYNN), Chipotle (CMG), Under Armour (UA), Reynolds American (RAI), and Northrop Grumman (NOC).
