Oct 4 (Reuters) - Egypt's blue-chip stock index sank 1.5 percent on Thursday, weakened by global jitters over emerging markets, while a merger between Saudi's Alawwal Bank and Saudi British Bank provided one of the few bright spots in the Gulf.
The Egyptian index fell to 14,105 points, close to this year's intra-day low of 14,055 points, as all but seven of the 30 stocks in the index dropped. The index lost 3.6 percent this week.
A Reuters poll of Middle East fund managers, published at the start of this week, found them on balance turning negative towards Egypt for the next three months, given the risk emerging-market turmoil will drive capital out of the country.
However, several fund managers said their positive long-term outlook for Egypt had not changed. MENA Capital called the market's drop a "passing phase".
"While the market could continue to trade sideways in the short term, we cannot justify a change in our view on Egyptian equities given current valuations, earnings per share growth, and the medium-term outlook for local interest rates," said Mohamad Al Hajj, head of regional strategy at EFG Hermes.
In a sign that underlying appetite for Egyptian equity remains solid, a private offer of shares in Egypt's Sarwa Capital was 10.83 times oversubscribed, said Beltone Financial, which is managing the sale of around 295 million shares in a private and public offer.
Meanwhile, the Saudi Arabian stock index edged down 0.1 percent as most banks were sluggish, but Alawwal rose nearly 3 percent to 14.62 riyals. SABB reversed early gains to close 1.1 percent lower at 31.90 riyals.
Under their binding deal, reached after the banks revealed merger talks earlier this year, SABB will pay for the merger by issuing new shares and the deal values each Alawwal share at 16.26 riyals, the banks said.
Although the agreement values Alawwal above market, SABB could benefit from increased size; the merger would create Saudi Arabia's third-biggest lender with market capitalisation above $17 billion, the statement said.
Alujain Corp continued to fall, dropping 2.8 percent after it said earlier this week that a fire broke out at its affiliate National Petrochemical Industrial's plant, halting production.
Dubai's real estate stocks continued to drag down its index , which closed 0.8 percent lower in its third straight session of losses. Emaar Properties sank nearly 3 percent.
Loss-making construction firm Drake & Scull, which had been rebounding recently, fell back 1.4 percent on the day of its shareholder meeting, which is expected to discuss ways to strengthen the company.
DAMAC Properties rebounded 1.5 percent; it slid on Wednesday after saying it expects Dubai's real estate market to face another few quarters of softness before starting to rebound from late 2019.
Oman's index was up 0.2 percent, helped by a memorandum of understanding between Al Izz Islamic Bank and Oman Arab Bank for a potential merger. Al Izz Islamic jumped 5.9 percent in heavy trade to its highest level since mid-2017.
SAUDI ARABIA * The index fell 0.1 percent to 7,998 points. DUBAI * The index slid 0.8 percent to 2,792 points. ABU DHABI * The index inched up 0.1 percent to 5,007 points.
