WASHINGTON (dpa-AFX) - Stocks have moved mostly higher during trading on Wednesday, largely offsetting the pullback seen in the previous session. The major averages have all moved to the upside, with the tech-heavy Nasdaq leading the way. In recent trading, the major averages have reached new highs for the session. The Nasdaq is up 178.73 points or 0.8 percent at 22,967.10, the S&P 500 is up 35.18 points or 0.5 percent at 6,749.77 and the Dow is up 133.10 points or 0.3 percent at 46,736.08. The strength on Wall Street partly reflects a notable advance by shares of Nvidia (NVDA), with the AI darling and market leading jumping by 1.8 percent. Nvidia is moving high after CEO Jensen Huang told CNBC's 'Squawk Box' artificial intelligence computing demand has increased 'substantially' in the last six months. Meanwhile, traders continue to shrug off the ongoing U.S. government shutdown, which has entered its eighth day today.
