US stocks managed to score modest gains on Friday, but the S&P 500 posted its biggest weekly drop since April as investors showed only mild enthusiasm after getting their first glimpses of earnings.

Shares of Wells Fargo & Co., which fell 0.6% to $51.49, were in the spotlight as the biggest US mortgage lender was the first major US bank to report earnings.

Wells Fargo's results will be followed next week by earnings from Citigroup, Goldman Sachs, JPMorgan Chase and Bank of America.

Next week's flurry of earnings will include reports from Google and Intel.

"This market is predicated on economic data, but above all else, it's on what companies are telling us. We need to hear from companies to give credence to whether or not the economy is gaining momentum versus losing traction," said Quincy Krosby, market strategist at Prudential Financial, based in Newark, New Jersey.

A bright spot was provided by Whirlpool Corp. The stock rose 1.1% to $140.76 after the US manufacturer of washers, dryers and other major home appliances agreed to buy a 60% stake in its smaller Italian rival Indesit Company SpA for about $1 billion.
