NEW YORK (Reuters) - U.S. stocks rose on Tuesday after new Federal Reserve Chair Janet Yellen reinforced the central bank's plan to trim its market-friendly stimulus while noting the health of the labor market needed to improve.
In her first public comments as Fed chief, Yellen, giving a balanced testimony to a House committee, acknowledged recent volatility in global financial markets but said it did "not pose a substantial risk to the U.S. economic outlook," and that she strongly supported the policy approach of her predecessor, Ben Bernanke.
Yellen's appearance before the House Financial Services Committee began at 10 a.m..
"We didn't see anything, at least in the written release that would cause us any concerns," said Paul Mangus, head of equity research and strategy at Wells Fargo Private Bank in Charlotte, North Carolina.
"Naturally the testimony is just beginning so that will be very interesting to watch, the written testimony was in many ways a continuation of what the Bernanke policies had been."
The Dow Jones industrial average <.DJI> rose 83.69 points or 0.53 percent, to 15,885.48, the S&P 500 <.SPX> gained 7.74 points or 0.43 percent, to 1,807.58 and the Nasdaq Composite <.IXIC> added 18.85 points or 0.45 percent, to 4,167.023.
The central bank has cut its bond-buying program by $10 billion at each of its last two meetings, reducing the monthly purchases to $65 billion.
Stocks also saw a potential headwind removed when Republican leaders in the U.S. House of Representatives caved in to demands by President Barack Obama and agreed to advance legislation raising Washington's borrowing authority.
