Russian shares slump as all trading resumes

MOSCOW — Russian shares have slumped as its stock market resumed trading of all companies after a monthlong halt following the invasion of Ukraine.

The benchmark MOEX index slid 2.2% Monday after the Moscow Exchange reopened for all of its several hundred listed companies, but with restrictions still in place to limit volatility.

The last full trading session in Moscow was on Feb. 25, a day after the index tumbled by a third after President Vladimir Putin ordered the invasion of Ukraine.

Prices whipsawed last week when the exchange tentatively reopened for two days of limited trading, with investors allowed to trade only 33 of the MOEX index’s 50 companies.

Some restrictions remained in place Monday to prevent another big selloff. The daily session is shortened to four hours and there is a ban on short-selling, which essentially involves betting on stock prices to go down. Foreigners also are unable to sell shares until Friday.
