NEW YORK, Dec 22 (Reuters) - U.S. stocks rose for a fourth straight session on Monday, with both the Dow and S&P 500 ending at records as large-cap technology shares gained and offset continued weakness in energy names.
Major indexes opened with slight gains but strengthened throughout the session, ending near their highs of the day. Despite that, trading was quiet with many market participants out ahead of the upcoming Christmas holiday.
About 6.41 billion shares traded on all U.S. platforms, according to BATS exchange data, compared with the month-to-date average of 7.86 billion.
Tech was the strongest sector of the day, with the S&P information technology sector up 1.1 percent. Intel Corp rose 2.3 percent to $37.21, providing the biggest boost to the Dow, while IBM rose 1.8 percent to $161.44 and Cisco Systems rose 1.6 percent to $28.22. Priceline Group rose 3.6 percent to $1,149.38. Continuación...
