Full Truck Alliance and Boss Zhipin — Chinese regulators also launched an investigation into Boss Zhipin and subsidiaries of Full Truck Alliance, which are both listed in the U.S. Shares of Boss Zhipin, listed under the name “Kanzhun,” fell roughly 10% in early trading. Full Truck Alliance shares plunged about 16% in the premarket.

Other Chinese companies — Shares of other Chinese companies publicly traded in the U.S. also dropped after regulators announced cybersecurity reviews. Baidu, Pinduoduo and JD.com shares fell roughly 2% in premarket trading.

3M —Shares of 3M fell slightly in early trading after Credit Suisse downgraded the industrial products stock to neutral from outperform, citing challenges with legal issues. “Despite fundamental potential upside from a cyclical upturn in global IP, and potential inventory restocking, we think it will be difficult for 3M to regain its premium multiple at this point in the cycle with two, still difficult to quantify liabilities,” analyst John Walsh said.

Pfizer — Shares of the pharmaceutical company fell roughly 1% after Israel’s health ministry reported a decrease in effectiveness in Pfizer’s Covid-19 vaccine in preventing infection and symptomatic disease. However, Israel said Pfizer’s Covid vaccine remained highly effective at preventing serious illness.
