Major benchmarks plunged on Friday after President Trump took to Twitter to call Federal Reserve Chairman Jay Powell an "enemy," likening the man he hand-picked for the job to Chinese President Xi Jinping. Trump followed that with a tweet "hereby" ordering "our great American companies" to "immediately start looking for an alternative to China," though it's unclear how the president might implement such an order.

By the end of the session, both the Dow Jones Industrial Average (DJINDICES:^DJI) and the S&P 500 (SNPINDEX:^GSPC) lost well over 2%.

Foot Locker trips up

Shares of Foot Locker plunged 18.9% after the footwear retailer told investors its second-quarter sales declined 0.4% year over year to $1.774 billion -- well below expectations for sales closer to $1.82 billion -- as currency headwinds more than offset a 0.8% increase in comparable-store sales. On the bottom line, that translated into adjusted net income of $72 million, or $0.66 per share, roughly $0.01 per share below consensus estimates and down from $0.75 per share in the year-ago period.

CEO Richard Johnson admitted the results arrived near the low end of the company's targets, but also noted its performance improved with each successive month in the quarter.

"We remain deeply connected with sneaker and youth culture," Johnson added, "and believe this positive momentum exiting the quarter has us well positioned for the back-to-school period and beyond."

Judging by today's drop, the market isn't convinced.

Salesforce's stellar quarter

Meanwhile, Salesforce stock gained 2.3% after the cloud-based customer relationship management (CRM) platform leader announced better-than-expected fiscal second-quarter results. Salesforce's revenue climbed 22% year over year to just under $4 billion. Adjusted net income arrived at $526 million, or $0.66 per share, down from $0.71 per share a year earlier (though its bottom line was negatively impacted by a recent $0.16-per-share reseller-agreement settlement).

Still, these results were well above Wall Street's consensus prediction for revenue of $3.96 billion and earnings of $0.47 per share.

Chairman and co-CEO Mark Benioff called it "an outstanding quarter" that left the company comfortable with increasing its full-year guidance to call for revenue growth of 26% to 27%, or to a range of $16.75 billion to $16.9 billion (up from $16.1 billion to $16.25 billion previously). Salesforce also reduced its full-year outlook for adjusted earnings per share to $2.82-$2.84 -- down from $2.88-$2.90 before, but technically marking an increase after accounting for the aforementioned reseller settlement.
