NEW YORK (AP) — Big Tech stocks pulled Wall Street down to its worst day in three weeks.

The S&P 500 fell 1% Tuesday, its second straight drop after closing last week at an all-time high. The Dow Jones Industrial Average also lost 1%, and the Nasdaq composite gave back 1.7%.

Apple was one of the heaviest weights on the market. It's been struggling on worries about sluggish iPhone sales in China.

Microsoft, Tesla and other influential stocks also sank.

Treasury yields fell after U.S. economic data was weaker than expected. Bitcoin touched a record high before tumbling.
