As we do prior to each earnings season, below we provide our list of the most volatile stocks on earnings.  From our online Earnings Report Database that contains data on more than 100,000 quarterly reports, we found the stocks that have historically experienced the largest move on their earnings reaction days.  The “earnings reaction day” is the first trading day following a stock’s quarterly report.  For stocks that report earnings before the open, the earnings reaction day is the day of the report.  For stocks that report after the close, the earnings reaction day is the next trading day.

To make the list below, a stock must have at least four quarters of earnings reports.  As shown, zulily (ZU) tops our list this quarter with an average move of +/-21.63% on its earnings reaction day.  TubeMogul (TUBE) ranks second with an average move of +/-20.04%.  FUEL, COUP and RALY round out the top five.

The most widely known names on the list are probably Groupon (GRPN), Twitter (TWTR), Yelp (YELP), Netflix (NFLX) and GoPro (GPRO).  Each of these stocks experience moves of more than +/-13% on their report days.

We’ve just published our Earnings Season Calendar that provides report dates and other useful information for all companies set to report their numbers through the end of July.  The Calendar is available to Bespoke Premium and Bespoke Institutional subscribers, and it is updated regularly throughout earnings season.  Sign up for a 5-day free trial to either service to check it out.
