Oct 23 (Reuters) - Most major Gulf indexes opened lower on Wednesday, with Saudi hurt by a slew of weak earnings, while Qatar extended losses for a fifth straight session.
In Saudi Arabia, the benchmark index dropped 0.3% with National Commercial Bank dropping 0.8% and Al Rajhi Bank losing 0.3%.
Sahara International Petrochemical (Sipchem) also slid 3.2% after it reported a more than 38% plunge in third-quarter net profit. The petrochemical maker said it was due to a decrease in selling prices for most of the products.
Saudi Arabia Mining Co declined 1.2% after it posted a third-quarter net loss of 92 million riyals, compared with a profit of 415 million riyals a year earlier.
The miner attributed the fall to decrease in sales volume of ammonia, aluminium and alumina.
