DUBAI: Middle East stock markets fell on Sunday after oil prices dropped to their lowest levels since March, and even better-than-expected earnings from the region's biggest listed firm, Saudi Basic Industries Corp., could not offset the overall gloom.

Brent and US crude futures on Friday posted their fourth straight weekly decline as weak economic data from China and a rise in US oil drilling rigs pressured them.

Gulf investors had ignored smaller oil price movements in the last few weeks, but with Brent below $55 per barrel and US oil under $50, crude once again grabbed their attention.

Petrochemicals giant SABIC rose 0.7 percent to SR99.00. But SABIC shares came well off their early high of SR102.75 and the main Tadawul All-Share Index fell 0.8 percent to 9,302 points as most banking stocks and other blue chips dropped. The Kingdom's biggest lender, National Commercial Bank, fell 1.5 percent.

Saudi Arabian Mining Co. (Maaden) lost 1.3 percent after the price of one of its products, copper, fell to a six-year low as Chinese manufacturing contracted by the most in 15 months in July.

Sahara Petrochemical Co. dropped 2.3 percent, having reported a 94 percent decrease in second-quarter profit.

Banque Saudi Fransi fell 2.6 percent as its shares no longer carried a semiannual dividend. Herfy Food was down 1.0 percent for the same reason.

Dubai's index fell 1.3 percent to 4,148 points as all but a handful of stocks declined. Lender Emirates NBD, down 2.3 percent, was one of the main drags on the benchmark. It had risen 10.4 percent last week on strong second-quarter results.

Amlak Finance, which had gained about 150 percent since the stock resumed trading in early June, dropped 3.6 percent. Many institutional investors believe the stock's dramatic rise was fueled by speculation and it is overvalued by commonly used metrics.

National Central Cooling Co. (Tabreed) was one of just a few gainers, climbing 0.7 percent after posting a 2 percent increase in second-quarter profit.

Abu Dhabi's market slipped 0.4 percent to 4,881 points and Abu Dhabi National Energy Co. (TAQA), whose earnings are sensitive to oil prices, tumbled 4.2 percent. Another energy firm, Dana Gas, fell 5.1 percent.

Qatar's index edged down 0.3 percent to 11,909 points and heavyweight Ezdan Holding was the main drag, sliding 1.1 percent ahead of its second-quarter earnings announcement. After trading closed, the firm which has interests in real estate, finance and other industries, reported a 30 percent rise in second-quarter net profit.

Egypt's market gave up early gains and closed 1.0 percent lower at 8,005 points with most stocks in the red.

"I think it's just profit-booking in some property names and banks," said Harshjit Oza, analyst at the Cairo-based Naeem brokerage.

Also, Palm Hills Development tumbled 6.2 percent ahead of the addition of new shares placed through a rights issue, which will dilute the existing stock.
