Stocks ripped higher on Wednesday after Federal Reserve Chairman Jerome Powell said interest rates are close to neutral, a change in tone from remarks the central bank chief made nearly two months ago.

The Dow Jones Industrial Average climbed 618 points, posting its biggest one-day gain since March 26. The 30-stock index also notched its second-best day of the year and is up more than 1,000 points for the week.

The S&P 500 jumped 2.3 percent as traders took the comments to mean fewer rate hikes were coming in 2019 that could derail the bull market. The Nasdaq Composite advanced 2.95 percent, its best day since Oct. 25. The Dow and S&P are now positive for November after Wednesday's comeback.

"Interest rates are still low by historical standards, and they remain just below the broad range of estimates of the level that would be neutral for the economy — that is, neither speeding up nor slowing down growth," Powell said in a speech at the Economic Club of New York on Wednesday.

Robert Pavlik, chief investment strategist at SlateStone Wealth, said Powell's comments were "exactly what the market was expecting to hear." He added: "Obviously it has to do with the market reaction to his previous comments. He had to walk that back."

The "just below" language is different from the "long way from neutral" characterization he gave at the beginning of October, which helped send the S&P 500 into a correction.

Bank stocks climbed as short-term borrowing rates fell and long-term rates rose following Powell's remarks. The SPDR S&P Bank ETF (KBE) rose 1.3 percent while Morgan Stanley, Goldman Sachs and Bank of America all closed more than 2 percent higher. J.P. Morgan Chase gained 1.1 percent.

Powell's comments were eagerly awaited by investors as they worried the central bank may be tightening monetary policy too quickly. The Fed is largely expected to raise rates by 25 basis points next month. The central bank has already hiked rates three times this year. Traders now see only one more hike fully prices in for 2019.

The Fed's decisions on monetary policy have drawn criticism from the White House recently. President Donald Trump told the Washington Post that he wasn't "even a little bit happy" with his appointment of Powell as the Fed's Chair, adding that he thought the central bank's recent actions were "way off-base."
