The Saudi Arabian stock market Tadawul opened strongly but failed to keep its momentum with a index gains above one percent. The benchmark Tasi index eventually finished at a three-month high at 6,453.13 (up 0.28%). Postive input from the U. S., where the Dow Jones Industrial Index gained 1.86% on Friday due to a slightly stronger report on durable goods orders, helped the GCC bellwether market. Petrochemical shares gained in particular, while the agriculture and telecom sector index posted losses.
