Wall St. rises; Internet, biotech names lift Nasdaq

By Ryan Vlastelica NEW YORK (Reuters) – U.S. stocks rose on Monday, with a rally in high-growth names among Internet and biotech shares giving the Nasdaq a gain of almost 1 percent. Equities have been pressured recently, with the S&P 500 coming off its first two-week decline since January as investors have become concerned about the economy's growth prospects. "The listlessness in the market shows the struggle investors are having right now: Valuations are full but not stretched, and there's a lack of decisive evidence that the economy will kick into higher growth and justify these valuations," said Mark Luschini, chief investment strategist at Janney Montgomery Scott in Philadelphia.
