CAIRO: Egyptian Stock Exchange chairman Mohamed Omran said, “I don't have any advice for investors during this critical stage.” Omran insisted the stock exchange will remain functional in light of recent events in Tahrir Square. He added there are no plans or new procedures being introduced to the market. Ashraf El Sharkawy, Head of the Egyptian Financial Supervisory Authority, said “precautionary measures that were used after the January 25 Revolution ensuring the protection of the stock market from collapse, are enough to protect the market during the current period.”
