 In spite of lackluster trading on Tuesday, Wall Street did produce some new records. Stocks closed mixed on Wall Street after testimony from Federal Reserve Chair Jerome Powell provided little new guidance on the Fed's plans for when it might lower interest rates. The S&P 500 and the Nasdaq Composite each rose one-tenth percent Tuesday, adding to their recent records. The Dow Jones Industrial Average fell 52 points. That's about one-tenth of a percent.
