NEW YORK, Jan 11 (Reuters) - The Dow and S&P 500 ended a volatile session slightly higher on Monday, recovering from recent sharp selling, but a drop in biotechs and energy shares weighed on the market along with caution ahead of earnings season.
The Dow Jones industrial average rose 51.78 points, or 0.32 percent, to 16,398.23, the S&P 500 gained 1.56 points, or 0.08 percent, to 1,923.59 and the Nasdaq Composite dropped 5.64 points, or 0.12 percent, to 4,637.99. (Reporting by Chuck Mikolajczak; Editing by Nick Zieminski)
