The market itself is up about 13% this earnings season as well. Below we highlight the individual stocks in the S&P 1500 that have seen the biggest 1-day gains and losses following their earnings reports this season. Trueblue (NYSE:TBI) has had the best response to earnings so far this season with a gain of 40.4% on the day. Other notable big winners include Intuitive Surgical (NASDAQ:ISRG) and Starbucks (NASDAQ:SBUX). On the downside, Spartan Motors (NASDAQ:SPAR), Lexmark (NYSE:LXK), and Allegheny Technologies (NYSE:ATI) have had the worst response to earnings.

While top line and bottom line numbers have been a major focus this earnings season as they usually are, the key to the big gains seems to be guidance. For the first time in a long while, many more companies are raising guidance versus lowering guidance, as companies are forecasting their businesses to finally start getting better instead of worse.
