Stocks rose higher on Tuesday, reversing earlier lows, after Federal Reserve Chair Jerome Powell said that inflation has shown some signs of easing. The Dow Jones Industrial Average climbed over 265 points, while the S&P 500 Index and Nasdaq Composite rose 1.3% and 1.9%, respectively.

Here's how the market settled on Tuesday:

S&P 500 Index (SPY  ): +1.29% or +52.92 points to 4,164.00

Dow Jones Industrial Average (DIA  ): +0.78% or +265.67 points to 34,156.69

Nasdaq Composite Index (QQQ  ): +1.90% or +226.34 points to 12,113.79

Stocks rallied higher on Tuesday shortly after Powell's remarks at the Economic Club of Washington D.C., with the Dow gaining more than 275 points at one point and the S&P 500 and Nasdaq Composite each jumping over 1%.

"The disinflationary process, and the process of getting inflation down, has begun and it's begun in the goods sector, which is about a quarter of our economy," Powell said Tuesday afternoon. "But it had a long way to go. There are the very early stages."

Commenting on the central bank's pace of interest rates moving forward, Powell said that if the data shows that inflation is running hotter-than-expected, the Fed will continue to raise rates.

"The reality is we're going to react to the data," Powell said. "So if we continue to get, for example, strong labor market reports or higher inflation reports, it may well be the case that we have to do move and raise rates more than is priced in."

Powell's Tuesday comments follow the Fed's policy decision last week, where Powell said in post-decision remarks that he believes the central bank is making progress in bringing down inflation. Wall Street has rallied higher throughout the start of the year on bets that cooling inflation will prompt the central bank to pause or even cut interest rates in the near- to medium-term.
