U.S. stocks ended a wobbly day on Thursday mostly lower

U.S. stocks ended a wobbly day mostly lower in what has been a rocky week because of worries coming out of the bond market about the U.S. government’s mounting debt.

The S&P 500 slipped less than 0.1% Thursday. The Dow Jones Industrial Average was little changed, and the Nasdaq composite rose 0.3%.

Treasury yields were also holding a bit steadier in the bond market, but only after oscillating earlier in the morning after the House of Representatives approved a bill that would cut taxes and could add trillions of dollars to the U.S. debt.

The S&P 500 fell 2.60 points, less than 0.1%, to 5,842.01.

The Dow Jones Industrial Average slipped 1.35 points, less than 0.1%, to 41,859.09

The Nasdaq composite rose 53.09 points, or 0.3%, to 18,925.73.

The Russell 2000 index of smaller companies fell 0.99 points, less than 0.1%, to 2,045.56.
