Shares of 3M fell more than 4% after the company cut its full-year earnings guidance. The stock's losses pressured the Dow for most of the session and outweighed positive results from Microsoft. The tech giant climbed nearly 2% after reporting earnings and revenue that topped analyst expectations. Microsoft's results were driven in part by strong sales from the company's cloud business. Wall Street digested these results — along with reports from Twitter, Tesla, and Dow Inc — during the busiest day of the earnings season.
Twitter's stock tumbled more than 20% on earnings that missed analyst expectations. The social media company said it faced product issues along with advertising "headwinds" during the previous quarter. Meanwhile, Tesla surged more than 17% after the electric car maker posted a surprise profit.
