Stocks added to gains on Friday as a series of big banks, including JPMorgan (JPM - Get Report) , beat Wall Street estimates.

The S&P 500 was up 0.7%, the Dow Jones Industrial Average rose 0.82%, and the Nasdaq added 0.79%.

JPMorgan rose nearly 2% after topping lowered earnings estimates in its recent quarter. Profit in the third quarter slid 7.6% as a volatile market and a low interest-rate environment depressed the bottom line. Per-share earnings of $1.58 fell a dime from a year earlier, but beat estimates of $1.39 a share. The largest U.S. bank by assets also reported a 8.4% increase in revenue to $25.51 billion, exceeding forecasts of $24 billion.

The big bank kicked off the earnings season for the financials sector. Financials endured a rocky quarter in the wake of the Brexit decision in late June which caused market turmoil. Banks have also had to weather an environment of low interest rates with a cautious Federal Reserve holding its monetary policy at crises levels.

Citigroup (C - Get Report) climbed after exceeding analysts' estimates on its top- and bottom-lines in its third quarter. The bank earned $1.24 a share, 8 cents above forecasts. Revenue slid 4% to $17.76 billion, edging past estimates by $420 million.

Wells Fargo (WFC - Get Report) also moved higher following a better-than-expected third quarter. The bank, which has recently been embroiled in a sales scandal, earned $1.03 a share over its recent quarter. Analysts had anticipated earnings of $1.01 a share. Revenue climbed nearly 2% to $22.3 billion, narrowly beating forecasts by $80 million.

Retail sales in the U.S. climbed 0.6% in September, a sign the consumer sector remains a strong point in the U.S. economy. Analysts had expected a slightly stronger increase of 0.7%. The measure rebounded from a slight decline in August. Excluding gas and autos, sales rose 0.3%, as expected, after a flat reading in August.

Sales at electronics and appliance stores fell 0.9% month over month in September, according to the retail sales data, a figure that spooked Best Buy (BBY - Get Report) investors. Sales fell 3.8% from the year-ago period. Analysts expected to see a boost in electronics spending after the September release of the iPhone 7. Best Buy shares fell 0.6% on Friday. 

"Consumers were still engaged in the economy during the third quarter but they were not as strong as the pace shown during the second quarter of the year," said Eugenio J. Aleman, senior economist at Wells Fargo. "Still, consumer demand remains in the driver's seat of U.S. economic performance."

The Fed may have to raise rates faster than current projections indicate, Boston Fed Eric Rosengren said on Friday. 

"My own view is that if the unemployment rate falls as much as I'm expecting, then it is possible that we'll have to raise rates faster than the summary of economic projections," Rosengren, a hawkish member of the Federal Open Market Committee, told CNBC. 

Rosengren anticipated the unemployment rate to decline to 4.5% next year, an unsustainable level that may force the Fed to act. Current projections put interest rates at just above 1% by the end of next year. Another rate hike at the December meeting is widely expected.
