 This is a Bloomberg Money Minute. Just minutes to go ahead of Wall Street's closing bell, and we're on track for another record-closing high for the Dow. But there was a big sell-off in tech stocks today, sending in the Nasdaq and the S&P sharply lower. Right now, the Dow up 0.6%, but the Nasdaq down 2.5%, and the S&P 1.25% lower. That's after the White House today threatened tougher trade penalties for countries allowing tech firms to sell advanced AI technology to China.
