CAIRO: The main Egyptian stock indexes today climbed sharply in the morning session spurned on by optimism and enthusiasm following yesterday's successful and largely peaceful parliamentary elections. The index spikes were so dramatic that trading was halted for 30 minutes so as not to exceed percentage limits. The main EGX30 index climbed 5.8 percent, or 191 points, the EGX70 jumped 4.98 percent, or 20 points, and the EGX100 gained 5.01 percent, or 33 points. Bluechip shares also made large gains, including International Trade Bank, up 6.06 percent; Orascom for Construction, up 5.8 percent; and Palm Hills, up 6.9 percent.
