Amazon.com, Caterpillar, McDonald's and General Motors are among the 50 odd companies reporting Thursday, making it the busiest day of the earnings season.

There's also a sprinkling of economic data, with weekly jobless claims at 8:30 a.m. ET, and leading indicators at 10 a.m.

Roughly 20 percent of S&P 500 companies reported as of Wednesday morning and 70 percent scored earnings beats, according to Thomson Reuters. Based on forecasts and actual reports, companies in the index are expected to see a 1.5 percent decline in profits.
