Big Tech carries Wall Street to the close of its winning, roller-coaster week

Big Tech stocks carried Wall Street to the close of a winning, roller-coaster week. The S&P 500 rose 0.7% to add some more to a big three-day rally, and it’s back within 10.1% of its record set earlier this year. Spurts for Nvidia and other influential tech stocks sent the Nasdaq composite up a market-leading 1.3%. But they masked a mixed day of trading, and the Dow Jones Industrial Average added only a modest 20 points. More CEOs said the uncertainty created by President Donald Trump’s trade war is making it difficult to give financial forecasts for the upcoming year.
