Trading volume fell for a second day in a row, indicating that investors were preparing for the Muslim holy month of Ramadan and were not expecting much from the opening of the Saudi market to direct investment by foreigners next week. Elsewhere in the Gulf, Kuwait's index slipped 0.3 percent but Mezzan Holding, a producer of food, medicines and consumer goods such as soap, surged 32.4 percent upon listing after a 65.8 million dinar ($217.9 million) private placement. Dubai's index dropped 2.7 percent as two stocks which had led gains in the last few days, Amlak Finance and Arabtec, both tumbled by the daily 10 percent limit.
