U.S. stocks fell on Thursday as oil prices slid, industrials dropped on worries over U.S.-China trade spat and Amazon led a decline in online retailers after the Supreme Court let states force the companies to collect sales tax.

Amazon dropped as much as 1.9 percent, before paring losses to trade down 0.3 percent. Wayfair, Overstock.com, Etsy, Ebay, and Shopify fell between 1.9 percent and 4.3 percent.

“Traders are very reactionary to Supreme Court news that could impact the balance sheet of online retailers,” said Andrew Thrasher, portfolio manager with Financial Enhancement Group LLC, based in Indianapolis, Indiana.

“Right now all online retailers and tech stocks are getting thrown out with the bath water, so to speak, before we truly understand the implications (of the ruling).”

Another big drag was Intel, which retreated 1.8 percent after Chief Executive Officer Brian Krzanich resigned following a probe that revealed that a past consensual relationship with an employee violated company policy.

Big U.S. manufacturers extended their slide after a state-controlled Chinese tabloid said Beijing could target members of the Dow Jones Industrial Average if President Donald Trump kept exacerbating tensions over trade.

Caterpillar dropped 0.8 percent and Boeing was down 1.2 percent, with the S&P industrials’ 0.73 percent slide weighing the most on the markets.

The 30-member Dow index gave up its year-to-date gains earlier this week as the trade rhetoric escalated and is on pace to extend a seven-session losing streak.

Ford slipped 1.2 percent, General Motors dropped 2.1 percent and Tesla declined 2.4 percent. The S&P 500 automobiles and components index was down 1.6 percent.

Earnings were a bright spot, with Darden Restaurants surging 12.1 percent and grocer Kroger jumping 9.3 percent after issuing strong quarterly results.
