NEW YORK (Reuters) - U.S. stocks rose on Friday and the Dow scored its biggest weekly percentage gain since June, as Goldman Sachs rounded out a week of strong quarterly earnings for the big banks.
Goldman Sachs Group shares jumped 3.8% and gave the Dow its biggest boost, as a record wave of dealmaking activity drove a surge in the bank's quarterly profit.
Goldman's report followed strong results from Bank of America and others this week. Banks were among the biggest positives for the S&P 500 on the day, and the index's bank index climbed 2.1%.
Results from big financial institutions provided a strong start to third-quarter U.S. earnings, though investors will still watch in coming weeks for signs of impacts from supply chain disruptions and higher costs, especially for energy.
Forecasts now call for third-quarter S&P 500 earnings to show a 32% rise from a year ago. The latest forecast, based on results from 41 S&P 500 companies and estimates for the rest, is up from 29.4% at the start of October, according to IBES data from Refinitiv.
"We're starting to get into an earnings-driven rally here that I hope lasts. We'll really see the results in the next couple of weeks as a great bulk of companies in all sectors report," said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia.
Alcoa Corp shares surged 15.2% after the aluminum producer reported stronger-than-expected results, announced a $500 million buyback program and initiated a quarterly cash dividend.

The Dow jumped 1.6% for the week, its biggest weekly percentage gain since June 25. The S&P 500 had its strongest weekly advance since July 23.

Moderna Inc shares fell 2.3%. A Wall Street Journal report, citing people familiar with the matter, said the U.S. Food and Drug Administration is delaying its decision on authorizing Moderna's COVID-19 vaccine for adolescents to check if the shot could increase the risk of heart inflammation.
