Even for the world’s worst-performing stock markets, Thursday’s losses were extreme.
China’s benchmark equity gauge closed 5.2 percent lower, the biggest loss since February 2016, as a global sell-off spread. More than 1,000 stocks fell by the daily limit, or more than one in four. The Shanghai Composite Index ended below 2,600, a level not even breached during market crashes in 2015 and 2016.
