NEW YORK – Stocks slid on Wall Street Thursday, a day after the Dow Jones industrial average logged its biggest one-day drop of the year, as investors fretted about the potential for gridlock in Washington.

The Dow closed down 121.41 points to 12,811.32, bringing its two-day loss to 434 points. The Standard and Poor's 500 index fell 17.02 points to 1,377.51 and the Nasdaq composite slipped 41.71 to 2,895.58.

The Dow plunged 313 points Wednesday, its fifth worst one-day drop following a U.S. presidential election. The biggest, in 2008, came in the midst of the financial crisis on the day after President Barack Obama won his first term.
