It's been a good quarter to do well.
S&P 500 companies that have beaten earnings estimates in the third quarter have seen their stocks rise by an average of 2.2 percent in the four-day period surrounding earnings, according to FactSet. That's double the 1.1 percent gain that earnings beaters have tended to enjoy.
Meanwhile, stocks that have missed earnings estimates have slid 2 percent from two days before earnings until two days after. In contrast, that's actually smaller than the average 2.2 percent decline.
Still, not many company have missed. Of the first 340 S&P 500 companies to report earnings for the third quarter, 76 percent of them have beaten estimates, FactSet reports, which is above historical averages.
Among the top gainers on earnings are semiconductor stock KLA-Tencor, which rose 23 percent in the four sessions surrounding earnings, real estate company CBRE Group, which jumped 11 percent in the similar period, and Abbvie, which rose 13 percent from two days ahead of earnings to Friday's close.
