Worries about inflation weighed on Wall Street, leaving major indexes mixed after another bumpy day of trading. The S&P 500 fell 0.1% and the Nasdaq lost 0.2% after being down even more earlier in the day. The Dow ended slightly higher. A government report showing that wage growth accelerated last month spooked investors since it could mean the Federal Reserve will be less able to ease up on its fight against inflation. The yield on the two-year Treasury, which tends to track expectations for future Fed action, rose following the release of the report, which also showed that hiring was stronger than anticipated.
