U.S. stocks fell, tracking a selloff in global equity markets, amid a deepening rout in all but the safest assets.

The Standard & Poor’s 500 Index slid 4.8 percent to 1,876.16 at 9:34 a.m. in New York, with the benchmark hitting its lowest level since October.

Calm in the U.S. market shattered last week, with volatility soaring by the most on record as the Dow entered a correction and investors dumped the biggest winners of 2015. A gauge of volatility expectations more than doubled last week. Shares succumbed to a global selloff that’s wiped more than $5 trillion off the value of equities around the world since China’s shock currency devaluation on Aug. 11.
