South Korea drastically limits short-selling

South Korea on Tuesday dramatically tightened rules on short-selling for three months, one day after its main equities board saw a record outflow by foreign investors as the coronavirus epidemic ravages the country's economy.
Starting March 11, stocks with a sudden and abnormal increase in short-selling transactions will be suspended from further short-selling for 10 days. The current rule calls for short-selling to be suspended for just one day. The rules will also kick in for a wider range of stocks, the Financial Services Commission said.
Stocks in the main KOSPI index that drop 5% or more and see daily short-selling transactions increase by three or more times than the average of the previous 40 days will be subject to the new rule.
