The S&P 500 and the Dow scored record closing highs on Friday, with the big boosts from financial stocks after banks reported strong quarterly results while the latest inflation data fueled expectations for a U.S. Federal Reserve rate cut in November.

Major financial companies kicked off earnings season with JPMorgan Chase finishing the session up 4.4% after the lender reported higher-than-expected third-quarter profit and raised its annual interest income forecast.

Other stocks in the industry rose broadly, making the S&P 500 Financials index the biggest index points boost for the benchmark.

"We'd some good earnings reports from some leading financial companies. That's a good start to earnings season," said Evan Brown, Portfolio Manager and Head of Multi-Asset Strategy, UBS Asset Management, adding that it bodes well for the economy.

"When financials do well, this is what a soft landing looks like. It's a positive overall sign for the economy and sets a positive tone for earnings releases in other industries in the next few weeks."

Friday's PPI data follows Thursday's Consumer Price Index (CPI) reading, which was slightly higher than forecast, although weekly jobless claims rose more than expected.

"The market's pretty convinced that we're going to have a soft landing and that inflation, even with CPI being a little bit higher than expected yesterday, is going to be moderate," said Scott Wren, senior global market strategist at Wells Fargo Investment Institute in St. Louis, Missouri.

"If you look at today's PPI data, the core and final demand were both a little lower than expected ... Inflation's certainly been moderating and that's a positive that the market paid attention to."

Meanwhile, a preliminary reading of the University of Michigan's October consumer sentiment index stood at 68.9, compared with analysts' estimate of 70.8.
