The Egyptian and Qatar exchanges plan to start derivative trading as the Arab bourses aim to increase liquidity and attract more foreign investments. The Egyptian Exchange is seeking to have derivatives listed by the second half of 2011, Maged Shawki, the head of the Egypt's CASE, said at a conference in New York Monday. The Qatar Exchange plans to offer derivative trading in three to five years, Andre Went, the chief executive officer of the exchange, said at the conference. “Our ambition is to create a more liquid, more diversified exchange,” Went said. “The objective is to attract foreign investors.”
