NEW YORK (Reuters) - U.S. stocks ended higher for the second straight session on Thursday, led by small-cap stocks, while the Nasdaq climbed on a rally in biotech shares.
The surge in biotech stocks extended the recent trend of volatile trading. Small-caps and the so-called momentum names in the Internet and biotech spaces have recently echoed the broader market's direction, but moved in an outsized fashion, often without specific news.
Among momentum names, noted for high growth and perceptions of excessive valuation, Vertex Pharmaceuticals
The Russell 2000 <.TOY> index of small-cap shares rose 0.9 percent, outperforming the broader S&P 500. The Russell fell into correction territory last week - defined as a 10 percent decline from a recent closing high - but has since retraced some of that, and is now less than 8 percent from its peak.
"Small-caps and momentum names are doing good today, but we really need another solid gain in the overall market for those high growth-oriented, high-risk stocks" to move away from the day-to-day volatile trading, said Tim Ghriskey, chief investment officer of Solaris Group in Bedford Hills, New York.

Housing stocks ranked among the market's biggest outperformers, with the housing index <.HGX> up 1.2 percent after existing home sales rebounded in April. Homebuilders were among the S&P 500's biggest gainers, with D.R. Horton Inc
The Dow Jones industrial average <.DJI> rose 10.02 points or 0.06 percent, to end at 16,543.08. The S&P 500 <.SPX> gained 4.46 points or 0.24 percent, to 1,892.49. The Nasdaq Composite <.IXIC> added 22.81 points or 0.55 percent, to close at 4,154.34.
The S&P 500 is about 10 points away from its record intraday high set on May 13. For the past week, the index has been caught between the high and its 50-day moving average as data left investors unsure about the pace of the economic recovery.
