Google's strong earnings and rocketing stock price may temporarily distract investors, but tension around U.S. debt ceiling discussions and the results of European bank stress tests Friday could quickly snap markets back to bigger concerns.

Google stock soared more than 10 percent after it reported that net income jumped to $8.74 a share or 2.51 million, a 36 percent increase and well above the $7.68 per share expected. Google revenues were $6.92 billion, well above the anticipated $6.55 billion.

"It's Googlicious and a lot of people were looking for it not to be very good.  A lot of shorts are out there in the name. They're covering. It's trading like water," said Steve Massocca of Wedbush Securities.

"I don't think it's going to make the market rally, but it's not going to hurt. It probably helps tech, and tech has been leading the market down. Earnings season is doing well so far. Alcoa was good. J.P. Morgan was good. Google was good," he said.

Citigroup is the big earnings report of the morning Friday, and it is expected to release results ahead of the opening bell. Genuine Parts and Mattel also report.

On the data front, markets are watching CPI and the Empire State survey at 8:30 a.m. and June industrial production at 9:15 a.m. Consumer sentiment is released at 9:55 a.m. Consumer prices are expected to have declined by 0.2 percent, with the decline in gasoline prices. The Empire survey is expected at 4.2, after a surprise decline in June.
