If you owned any of these names heading into their earnings reports, your portfolio certainly got a nice boost!

At the top of the list is Supervalu (SVU) with a one-day gain of 65.40% on its earnings reaction day.

The stock closed at $19.45 on the day prior to the announcement.

While SVU’s gain of 65.4% was due to a buyout announcement, Bridgepoint Education’s (BPI) one-day move of 52.90% was all earnings related.It’s nice when your stock moves 50%+ in a day, right?

Rounding out the list of the five biggest winners this earnings season are the Container Store (TCS), Boingo Wireless (WIFI), and Cardtronics (CATM). All three of these stocks had one-day gains of more than 30% on their earnings reaction days.

As you scroll down the list of winners, you’ll see a few names that you recognize — SodaStream (yes, it’s still around), GoPro (yes, it’s still around too), iRobot (IRBT).

Given the negativity surrounding the company heading into its report this season, Tesla (TSLA) is probably the stock whose 16.19% gain surprised the most people. With 27% of its float sold short, TSLA’s gain also put a hurting on Elon Musk non-believers.
