MIDEAST STOCKS-Egypt snaps winning streak, while MSCI upgrade keeps lifting Kuwait

* Egypt ends four days of gains * Kuwait rises for a sixth day * Yansab slides after trading ex-dividend * Property shares strong in Abu Dhabi By Ateeq Shariff July 4 (Reuters) - Egypt's blue-chip index snapped four straight days of gains on Thursday as most of its stocks dropped, while Kuwait rose for the sixth consecutive session after MSCI decided to upgrade Kuwaiti equities to its main emerging markets index. Egypt's blue-chip index slipped into negative territory after four days of gains. The index was down 0.9% with Egypt Kuwait Holding losing 4.2%. Egypt's current account deficit widened to $7.6 billion in the first nine months of the fiscal year from $5.47 billion a year earlier, while net foreign direct investments narrowed in the same period. The Saudi index slipped 0.1% led by a 0.4% fall in Saudi Basic Industries and a 0.7% drop in Riyad Bank . Yanbu National Petrochemicals dropped a further 1.3% after falling 2.7% the previous day when it traded ex-dividend. Qatar's index dipped 0.2%, putting an end to a five-day winning streak. Market heavyweight Industries Qatar lost 0.6% and Qatar Insurance decreased 1.4%. The index has been gaining in recent sessions as a 10-to-one stock split for companies on the exchange is being phased in from June 9 and will be completed by July 7. The move is designed to boost liquidity by encouraging smaller investors to buy shares. In Dubai, the index also slid 0.2 giving up early gains, with its largest lender Emirates NBD losing 0.4%. Kuwait's index added 0.6%. Last week, index compiler MSCI said it would move Kuwaiti equities to its main emerging markets index in 2020, a move that could trigger billions of dollars of inflows. Kuwait has outperformed its Gulf peers in anticipation of the MSCI move, gaining over 24% in the year-to-date. Middle Eastern funds plan to continue increasing investments in Kuwait over the next three months, a Reuters poll found earlier this week. The Abu Dhabi index rose 0.2% mainly helped by its property developer Aldar Properties which closed 2.6% higher. SAUDI ARABIA The index slid 0.1% to 8,847 points ABU DHABI The index edged up 0.2% to 4,999 points DUBAI The index lost 0.2% to 2,661 points QATAR The index was also down 0.2% at 10,566 points EGYPT The index declined 0.9% to 13,997 points BAHRAIN The index added 0.9% to 1,511 points OMAN The index fell 0.1% to 3,823 points KUWAIT The index increased 0.6% to 6,544 points ($1 = 3.7502 riyals) (Reporting by Ateeq Shariff in Bengaluru Editing by Edmund Blair)
