Most Gulf stocks edge lower as trade lacks impetus over investors' concern on the health of the world economy. The Saudi Tadawul All Share Index (TASI) was down 2.42 percent to 5,770.95 points, its largest one-day reverse for eight sessions. TASI declined to 5.5 percent on Monday. Of the major Saudi companies, Saudi Telecom Co (STC) was down 0.49 percent at SR50.75 and mining group Ma'aden was down 0.33 percent at SR15.00. The Dubai Financial Market DFM could not sustain its positive momentum from Sunday, closing 1.43 percent lower at 1,709.80. Emaar, after gaining over 12 percent on Sunday, dipped 2.37 percent on profit booking. The DFM stock itself lost 3.08 percent. However, the DFM showed signs of edging back today by 0.35 percent to reach 1,715.70 at 11.04 A.M. local time. The Abu Dhabi Securities Exchange was down 0.42 percent at 2,611.62. The DFM is the only Arab market with public listed shares, apart from the Nasdaq Dubai whose mother company Nasdaq OMX is listed in Dubai and New York.
