The Dow Jones Industrial Average rebounded after a tumultuous run last week, jumping nearly 670 points by the time markets closed Monday afternoon. The index surged nearly 3 percent in part thanks to Microsoft, the top-performing stock of the day. The gains suggest the market is recovering after President Trump last week announced tariffs targeted at China, which sparked fears of a trade war between the world's two biggest economies. Investors "have apparently recognized that a trade war is in no one's best interests and therefore extremely unlikely," market strategist Jeremy Klein told CNBC in explaining the rebound. The S&P 500 also saw a more than 2 percent bump Monday, while the Nasdaq composite jumped 2.6 percent.
