NEW YORK (AP) — Stocks wound up mostly higher on Wall Street Friday after another day of bouncing around as traders try to figure out what’s next for the economy. It was a fitting ending for a bumpy week that had both gains and losses for major U.S. indexes. The S&P wound up with a gain of 0.5% after another day of sudden movements both up and down. The tech-heavy Nasdaq ended with a loss of 0.2% and the Dow rose 0.4%. Treasury yields rose sharply again and crude oil prices rose moderately.
