Saudi Arabia’s Stock Exchange has announced short-selling changes have been introduced. Under the changes, all eligible investors will be able to sell any stock short or stock-lend. However, new rules state the short ratio to average daily traded volume of any security should not exceed 10 days. Total net short positions should not exceed 10% of the free float. Collateral rules for those lending and borrowing securities have also been amended. The amendments are aimed at developing a regulatory environment consistent with international best practices.
