The EGX just got an “undo” button on suspicious bourse trades: The Financial Regulatory Authority (FRA) has approved a proposal from the EGX allowing it to prompt securities brokers to reverse transactions that appear to have violated trading rules, according to an EGX press release. The move hands the bourse a policy tool to reverse suspect trades while avoiding more extreme action that could impact market stability, the press release read. The EGX will sort out how to make sure that any reversed transactions would be set aside in the calculation of any given share’s closing price, it added.

How it works: Under the rules — which have long been in place, but have not been enforced until now — the EGX can immediately compel the buyer to sell the shares back to the seller, reversing the transaction.

The regulators still have teeth: The EGX also got FRA approval to expand the use of “other measures” to crack down on trading violations, the statement said, without providing further information.
