Shaking off geopolitical flare-ups for now, analysts say the S&P 500 is taking aim at the 2,000 level, and the next round of earnings news could help.

Dozens of major companies reported Wednesday ahead of the open, and an even bigger batch report Thursday. On Wednesday, Boeing, Pepsico, Norfolk Southern reported ahead of the opening bell. AT&T, Facebook and Gilead report after the close. Of the 115 S&P 500 companies that reported as of Tuesday morning, 66 percent have beaten earnings per shares estimates and 64 percent beat revenue forecasts, according to Thomson Reuters.
