NEW YORK (Reuters) - Stocks ended with modest gains on Monday as investors digested recent market gains and looked ahead to new Federal Reserve Chair Janet Yellen's first testimony before lawmakers.
The Nasdaq was boosted by strength in large-cap tech and pharma names, but most market participants took a wait-and-see attitude ahead of the testimony, looking for confirmation that the Fed would not change its schedule for ending its support for the economy.
The U.S. central bank's accommodative monetary policies have been credited with fueling the market's steep gains in 2013, and are expected to keep a floor under equity prices for as long as they continue.
The Fed first announced a slowing in the bond-buying program in December, followed by another one in January. If it changes the pace of tapering - and uncertainty in emerging markets and the weak January payrolls have raised the odds of that to some - it may raise concerns that the economy is still not strong enough to strengthen on its own.
"We're hoping to hear Yellen strike a balance where she recognizes that the recovery is fragile, but not so much that the Fed changes its mind, which would be too premature of a signal to send," said Leo Grohowski, chief investment officer at BNY Mellon Wealth Management in New York.
Yellen's prepared remarks will be available before the market opens on Tuesday. She will also participate in a question-and-answer session with U.S. lawmakers after the open.
The Dow Jones industrial average (^DJI) was up 7.71 points, or 0.05 percent, at 15,801.79. The Standard & Poor's 500 Index (^GSPC) was up 2.82 points, or 0.16 percent, at 1,799.84. The Nasdaq Composite Index (^IXIC) was up 22.31 points, or 0.54 percent, at 4,148.17.
The S&P 500 is coming off its best two-day performance in four months, which capped the index's first weekly gain in the past four. Those gains were preceded by the index's sharpest pullback in months.
"Last week investors received a wake-up call that 2014 is unlikely to be like 2013 in terms of the return or the smoothness of the ride," said Grohowski, who helps oversee $185 billion in client assets. "We're still digesting last week's volatility, but investor sentiment is now neutral or negative, which is a positive for markets."
