What happened Shares of the payment processing company Shift4 Payments (NYSE: FOUR) fell nearly 11% today. There seems to be some news surrounding the company and potentially driving the move. So what The company released a brief update on October payments volume, saying payments volume in October grew 80% from October 2020, while active merchant counts have jumped 25% on a year-over-year basis. But seeing as this is good news, it is unlikely to have driven the stock down. What seems to be driving the dip has to do with recent news regarding an FBI raid of the U.S. operations of the Chinese company Pax Global Technology, a maker of payments terminals. Pax sells these terminals to companies all over the world. The cybersecurity website KrebsOnSecurity reported that the FBI raid may be related to the potential role of Pax-manufactured terminals in cyberattacks on companies in the U.S. and European Union.

The stock at one point today fell nearly 20% but clawed back about half of the loss. Any time the government or regulators get involved, things can get a little dicey, so investors may have just gotten scared. I expect the news regarding Pax may be brought up at Shift4's earnings call on Nov. 10, so be sure to tune in to learn more. 10 stocks we like better than Shift4 Payments, Inc.When our award-winning analyst team has a stock tip, it can pay to listen.
