AN ALGERIAN stock exchange will open its doors on February 15 after lengthy delays says Ali Boukrami, chairman of the Algerian Securities Commission on Monday. The opening will coincide with the listing of 20% of the biggest domestic pharmaceutical firm, Saidal. The company will offer two million shares at a price of 800 dinars ($13,5) a share.
