Stocks ended a wobbly day with mixed results Wednesday after the Federal Reserve said it was seeing improvement in the economy, but not enough to start dialing down its support measures.
The S&P 500 ended little changed after giving up a brief gain in the afternoon. The latest company earnings have been broadly solid, though reactions from investors have been mixed. Pfizer and Boeing rose after reporting strong financial results.
The S&P 500 fell 0.82 points, or less than 0.1%, to 4,400.64.
