U.S. stock indexes are ticking higher following some mixed signals on big banks’ profits and on inflation. The S&P 500 rose 0.2% in early Friday trading. The Dow Jones Industrial Average was up 143 points, and the Nasdaq composite was 0.1% higher. Bank of New York Mellon and Fastenal jumped to some of the market’s biggest gains after reporting stronger profit than expected for the spring, but Wells Fargo dragged on the market after warning of pressure on a key measure of profits. Treasury yields swung in the bond market after a report showed inflation at the wholesale level was worse than expected.
