Musk has been leading U.S. government efforts to cut spending, making him a target of growing political anger, and protests have swarmed Tesla showrooms as a result. On the winning side of Wall Street was Mr. Cooper, which jumped 14.5% after the home loan servicer said it’s being bought by mortgage company Rocket in an all-stock deal valued at $9.4 billion. The deal comes just weeks after Rocket acquired real estate listing company Redfin, and Rocket’s stock fell 7.4%. Warren Buffett’s Berkshire Hathaway rose 1.2% and was one of the strongest forces lifting the S&P 500. Newsmax surged 735% in a dizzying first day of trading for the stock of the news company. Its price was so volatile that trading of its stock was briefly halted a dozen times through the day. In other dealings early Tuesday, U.S. benchmark crude rose 17 cents to $71.65 per barrel, while Brent crude, the international standard, was up 19 cents at $74.96 per barrel. The dollar fell to 149.57 Japanese yen from 149.97 yen. The euro rose to $1.0825 from $1.0817. AP Business Writers Stan Choe and Matt Ott contributed.
