Updated from 2:43 p.m. EDTStocks in New York had a volatile session Wednesday before closing higher, paced by gains in technology shares. At the close, the Dow Jones Industrial Average had gained 47.55 points, or 0.6%, to 7837.11, and the S&P 500 added 9.61 points, or 1.2%, to 825.16. The Nasdaq was up 29.05 points, or 1.9%, to 1590.66. The market had been higher early, but it pulled back after the Federal Reserve released the minutes of its March meeting. The minutes indicated that "the staff's projections for real GDP in the second half of 2009 and in 2010 were revised down, with real GDP expected to flatten out gradually over the second half of this year and then to expand slowly next year as the stresses in financial markets ease, the effects of fiscal stimulus take hold, inventory adjustments are worked through, and the correction in housing activity comes to an end."
