The Dow Jones Industrial Average hit a record. It rose 218 points, or 0.5%, on Tuesday and topped its prior all-time high, which was set early this month. The S&P 500 index, which is much more important on Wall Street and dictates the performance of many more 401(k) accounts, was essentially flat and finished 0.3% below its own record. Strong earnings reports from 3M, Coca-Cola and others helped drive the gains. But some Big Tech stocks faltered and pulled the Nasdaq composite down 0.2%. The price of gold took a break from its torrid run this year and fell.
