Google, the world's third-largest company by market value, jumped 3.7 percent after second-quarter revenue exceeded analysts' projections as the company sold more advertising alongside Web-search results.

The S&P 500 rose 1 percent to 1,978.22 at 4 p.m. Friday in New York, marking its biggest gain in three months and capping a weekly advance of 0.5 percent. The Dow climbed 123.37 points, or 0.7 percent, to 17,100.18. The Russell 2000 Index of smaller companies rallied 1.6 percent, paring its weekly loss to 0.7 percent.

"I think when all these things hit the headlines, there's a knee-jerk reaction," Jim Paulsen, who helps oversee $357 billion in assets as chief investment strategist at San Francisco-based Wells Capital Management, said in a phone interview. "Traders reacted yesterday and it's bringing in investors today. Maybe they're thinking of buying and all of a sudden stocks got a lot cheaper."
The gain in the S&P 500 erased almost all of Thursday's 1.2 percent decline in the S&P 500 as the market resumed an advance that has added more than $1 trillion to share values in 2014. Stocks rose as Google's results helped bolster Wall Street forecasts for annual S&P 500 earnings growth of about 8 percent this year amid an expansion in gross domestic product forecast by economists to exceed 3 percent in the next two quarters.
The S&P 500 on Thursday ended a string of 62 straight days without a gain or decline of more than 1 percent.

President Barack Obama said the violence in Ukraine is facilitated by Russia's support for separatists and called for an immediate cease-fire.
Stocks extended losses late on Thursday after Israel began a ground operation in the Gaza Strip.

Equities have rallied this year amid better-than-estimated corporate earnings and central bank stimulus as the U.S. economy shows signs of recovering from a 2.9 percent contraction in the first quarter. The S&P 500 closed at a record on July 3 while the Dow reached an all-time high on Wednesday.
The index of U.S. leading indicators rose in June for the fifth straight month, showing the economy continues to gain momentum following a slowdown at the start of 2014.

All 10 main industries in the S&P 500 advanced. Health-care and technology stocks climbed more than 1.3 percent for the best performances.

General Electric slipped 0.6 percent as it reported profits that matched estimates. The company said it will hold an initial public offering for the Synchrony Financial unit, its Capital's North American consumer operations, this month.
AMD tumbled 16 percent, the biggest drop since 2012. The third-quarter sales projection may indicate the chipmaker isn't benefiting from a rebound in corporate spending on computers that has buoyed other companies in the personal-computer industry.
