NEW YORK, April 25 (Xinhua) -- U.S. stocks finished higher in choppy trading on Monday, buoyed by a rally in tech names.

       The Dow Jones Industrial Average rose 238.06 points, or 0.70 percent, to 34,049.46. The S&P 500 added 24.34 points, or 0.57 percent, to 4,296.12. The Nasdaq Composite Index increased 165.56 points, or 1.29 percent, to 13,004.85.

       Earlier in the day, all the three major averages dropped with the 30-stock index down 488 points at its session lows.

       Six of the 11 primary S&P 500 sectors ended in green, with communication services and technology up 1.53 percent and 1.44 percent, respectively, outpacing the rest. Energy tumbled 3.34 percent, the worst-performing group.

       Despite Monday's rally, analysts warned that market volatility is likely to continue amid growing concerns about the pace of monetary tightening.

       Federal Reserve Chair Jerome Powell affirmed last week the U.S. central bank's determination to bring down inflation, indicating a 50-basis-point hike was "on the table" at the May policy meeting.

       "With the Fed talking tough about persistent inflation, fears about a Fed induced recession will remain elevated until the data offers clear support for moderating inflation," Mark Haefele, chief investment officer at UBS Global Wealth Management, said Monday in a note.

       For the week ending Friday, the Dow and the S&P 500 slid 1.9 percent and 2.8 percent, respectively, while the tech-heavy Nasdaq shed 3.8 percent.
