Facebook, which cancelled its global marketing meeting scheduled for San Francisco in March because of coronavirus fears, saw its stock price tumble 4.5 percent or $9.46 a share at the closing bell. The social media giant also cancelled executives travel plans to China — the epicenter of the outbreak.

The downturn was also driving down prices on the other FAANG stocks that form a backbone on Wall Street for Silicon Valley.

Amazon, which joined Ericsson, Facebook, Sony, Intel and Cisco to pull out of World Mobile Congress, which was eventually cancelled, saw its stock drop 4.14 percent or $86.68 a share. Netflix was off nearly 3 percent or $11.37 a share.

Apple, whose component supply lines in China have been impacted by the outbreak, dropped 4.75 percent or $14.87 share. The company warned its investors last week that it won’t meet its second-quarter financial guidance because the outbreak cut production of iPhones.

Meanwhile, shares of Alphabet (Google) fell by 4.29 percent or $63.60 a share.
