Oct 9 (Reuters) - U.S. stocks closed slightly higher on Friday, ending the S&P 500's best week for 2015 on a quiet note as investors waited for U.S. companies to report third-quarter earnings.
The S&P 500 had a weekly gain of 3.3 percent, its best week since Dec. 2015, as investors regained some optimism after a period of heavy volatility since late August on concerns about global growth and uncertainty about U.S. interest rates.
"We've had a very good week and a very good start to the fourth quarter," said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia. "Next week third quarter earnings season begins in earnest. You had disappointing results from Alcoa yesterday and further reason to take money off the table as you go into next week."
Investors are anxious to gauge how companies are faring amid U.S. dollar strength and concerns about growth in China, the world's second biggest economy.
