Stock market today: Wall Street drifts to a mixed close in thin trading following a holiday pause

Stock indexes drifted to a mixed finish on Wall Street Thursday, as some heavyweight technology and communications sector stocks offset gains elsewhere in the market.

The S&P 500 fell less than 0.1% after spending the day wavering between small gains and losses. The tiny loss ended the benchmark index's three-day winning streak.

The Dow Jones Industrial Average added 0.1%, and the Nasdaq composite fell 0.1%.

Trading volume was lighter than usual as U.S. markets reopened following the Christmas holiday.
