US stocks were higher in early afternoon trading on Wednesday, with the Dow at record levels, after Federal Reserve Chair Janet Yellen said interest rates hikes would be gradual and will not have to rise much further to reach a neutral level.
Yellen, in a prepared testimony delivered to Congress, said the Fed would wind down its massive bond portfolio while keeping a close watch on the low inflation.
The testimony depicted an economy that, while growing slowly, continued to add jobs, benefited from steady household consumption and a recent jump in business investment.
Investors and some Fed officials, concerned with the recent dip in inflation, have been wanting to see a surer progress toward the central bank's goal of 2 per cent inflation.
Yellen said some temporary factors appear to be at work in holding down inflation but the Fed was focused on achieving the target.
"It was a little bit more dovish than most had thought," said Richard Scalone, co-head of foreign exchange at TJM Brokerage in Chicago.
"She said rates won't have to rise much further to get to neutral, I thought that was key. She said inflation response to economy is a key uncertainty, alluding to the inflation again, part of the dovishness."
The US central bank will also issue its Beige Book at 2 pm ET, a compendium of anecdotes on the health of the economy. The Fed's next policy meeting is on July 25-26.
At 12:47 pm ET (16:47 GMT), the Dow Jones Industrial Average was up 111.34 points, or 0.52 per cent, at 21,520.41, slightly easing from its record high of 2158.79.
The S&P 500 was up 16.2 points, or 0.667895 per cent, at 2,441.73 and the Nasdaq Composite was up 56.47 points, or 0.91 per cent, at 6,249.78.
Microsoft, Facebook and Amazon gave the biggest boost to the S&P and the Nasdaq.
Amazon shares edged up 1 per cent after the online retailer said its Prime Day sale was the biggest shopping event by sales in its history.
Ten of the 11 major S&P 500 sectors were higher, with the real estate index's 1.26 per cent rise leading the advancers.
The financial index, which is sensitive to rate hikes, was the only laggard and was trading little changed.
Chances of an interest rate hike at the Fed's December meeting fell to 53 per cent from 60 per cent after the release of Yellen's testimony, according to CME Group's FedWatch tool.
Investors will be keeping an eye on second-quarter earnings reports on Friday from big US banks including JPMorgan Chase, Wells Fargo and Citigroup.
