The European Securities and Markets Authority (ESMA) renewed the prohibition on emergency short selling in Greece. The ban took effect on 4 August 2015 and remains in place until 24:00:00 (CET) on 31 August 2015. It temporarily prohibits transactions in any financial instrument that creates, or increases, a net short position on any of the shares admitted to trading on the Athens Exchange and Multilateral Trading Facility. The renewal differs from the previous restrictions as it includes an exemption for market makers as the Greek financial markets are now open and market making activities are important providers of liquidity for the Greek shares, as well as for warrants, derivatives, index derivatives and ETF related to Greek shares.
