Not one S&P 500 (NYSEARCA:SPY) company cracked the list of the 30 best performing US stocks on their report days this past earnings season. Supervalu (NYSE:SVU) was the best performing S&P 500 stock in response to earnings with a one-day gain of 16.85%.

None of the top seven best performing S&P 500 stocks this earnings season came from the Technology sector, but the top five worst performing S&P 500 stocks this earnings season were in the Technology sector.

Other notables on the list of S&P 500 losers this earnings season include Netflix (NASDAQ:NFLX), Google (NASDAQ:GOOG), Hewlett-Packard (NYSE:HPQ), First Solar (NASDAQ:FSLR), and Alcoa (NYSE:AA).
