Stocks held another choppy session on Wednesday as investors continued to weigh signs that U.S. economic growth may be slowing. The Dow Jones Industrial Average seesawed between gains and losses, ultimately ending the day higher, while the S&P 500 and Nasdaq Composite both slipped into a negative flatline.

Wall Street's latest wave of volatility comes as renewed fears over inflation's impact on the U.S. economy. On Wednesday, first-quarter GDP was revised lower to show a 1.6% annualized contraction, adding to recession fears. This report follows a Tuesday report that saw consumer short-term expectations fall to a near decade low, raising concerns that consumers may cut spending in certain areas in anticipation of higher prices.

On Wednesday, Federal Reserve Chairman Jerome Powell said the central bank will not allow inflation to persist across the U.S. economy over the longer term.

"We're strongly committed to using our tools to get inflation to come come. The way to do that is to slow down growth, ideally keeping it positive," Powell said at a European Central Bank forum on Wednesday. "Is there a risk that would go too far? Certainly, there's a risk. I wouldn't agree that it's the biggest risk to the economy. The bigger mistake to make ... would be to fail to restore price stability."

Here's how the market settled on Wednesday:

S&P 500 Index (SPY  ): -0.07% or -2.85 points to 3,818.70

Dow Jones Industrial Average (DIA  ): +0.21% or +80.93 points to 31,027.92

Nasdaq Composite Index (QQQ  ): -0.03% or -3.65 points to 11,177.89
