Sinking technology stocks sent Wall Street lower again, and the S&P 500 fell to its fourth straight loss.

The index dipped 0.6% Wednesday for its longest losing streak since early January. The Dow Jones Industrial Average edged down by 0.1%, and the Nasdaq composite fell 1.1%. Tech stocks slumped after ASML, a Dutch company that’s a major supplier to the semiconductor industry, reported weaker orders than analysts expected. That helped overshadow stronger quarterly profit reports than expected from United Airlines and other big companies. Treasury yields fell following a sharp tumble in oil prices.

On Wednesday:

The S&P 500 fell 29.20 points, or 0.6%, to 5,022.21.

The Dow Jones Industrial Average fell 45.66 points, or 0.1%, to 37,753.31.

The Nasdaq composite fell 181.88 points, or 1.1%, to 15,683.37.

The Russell 2000 index of smaller companies fell 19.53 points, or 1%, to 1,947.95.
