US stocks stumble, erasing some of the prior day’s gains

Technology and health care companies drove a broad slide in U.S. stocks Wednesday, erasing some of the market’s solid gains from a day earlier.

The sell-off put the Dow Jones Industrial Average on track to end the month with a loss and marked the second drop for the benchmark S&P 500 index this week.

While U.S. stocks remain on track to finish the quarter with solid gains, investors remain anxious over the slowing global economy and worrisome signals coming from the bond market.

The yield on the benchmark 10-year Treasury note continued to decline Wednesday, dropping to 2.38 percent from 2.41 percent late Tuesday. That remained below the yield on the three-month Treasury bill. When that kind of “inversion” in bond yields occurs, economists fear it may signal a recession within the coming year.
