Stocks ended a wobbly day on Wall Street with mixed results Wednesday as investors weighed the latest corporate earning reports and the Federal Reserve chair's comments on inflation.

Technology companies made broad gains, while banks were mostly weaker after several of them reported their quarterly results. American Airlines rose after giving investors a strong outlook.

Energy companies had some of the biggest losses, partly due to a drop in the price of benchmark U.S. crude oil.

The yield on the 10-year Treasury note fell to 1.34%.

Federal Reserve Chair Jerome Powell reaffirmed the central bank's position that inflation will eventually ease.
