At the start of each earnings season, we provide an updated list of the most volatile stocks on earnings. Using our Interactive Earnings Database, below is a list of the S&P 500 stocks set to report earnings over the next month that have historically had the biggest price swings on their earnings reaction days. (For stocks that report before the open, their earnings reaction day is that trading day. For stocks that report after the close, their earnings reaction day is the next trading day.)
As shown, Netflix (NFLX) is the most volatile S&P 500 stock on earnings with an average move of +/-13.69% on its earnings reaction day. Align Tech (ALGN) ranks second at +/-11.32%, followed by Priceline (PCLN) in third at +/-11.19%. Akamai (AKAM), Intuitive Surgical (ISRG), and TripAdvisor (TRIP) are the only other stocks in the S&P that average one-day swings of more than 10% on their earnings reaction days.
Other stocks in the S&P 500 that experience huge moves in reaction to earnings include names you might expect like Amazon (AMZN), NVIDIA (NVDA), AMD, Chipotle (CMG), Facebook (FB), Alphabet (GOOG), and Wynn Resorts (WYNN). What is somewhat of a surprise, though, is that many of these stocks are now among the largest in the world. For such large stocks to see large swings like that is uncommon relative to history.
Next to each stock we also include when it’s expected to report this season, so keep an eye out if you own or follow any of these volatile large-cap names.
The table above highlights the most volatile S&P 500 stocks set to report earnings over the next month. Below is a list that looks at all stocks traded on US exchanges. The 40 stocks below must have at least 12 earnings reports (3 years worth of earnings) on file. As shown, Groupon (GRPN) is the single most volatile stock on earnings in the US that’s set to report over the next month. When it reports earnings, it typically moves up or down roughly 18% on its earnings reaction day. That’s a big move considering that it happens once every 3 months!
Rubicon Project (RUBI) is the second most volatile stock on earnings at +/-16.51%, followed by ServiceSource Intl (SREV), YELP, ChannelAdvisor (ECOM), and Rocket Fuel (FUEL). Other notables on the list include LendingTree (TREE), Netflix (NFLX), Tableau Software (DATA), First Solar (FSLR), FireEye (FEYE), and Twitter (TWTR).
