Abu Dhabi stocks leapt 4% on Thursday, their biggest intra-day gain in nearly four months, led higher by the United Arab Emirates' largest lender First Abu Dhabi Bank (FAB) which surged 6.5% on strong second-quarter earnings.

Similarly shares in Dubai bank Emirates NBD rose 3.5% thanks to positive quarterly results, leading gains on the Dubai index which was up 1.7%.

On Wednesday FAB reported a 5% increase in net profit in the second quarter from a year earlier, while Emirates NBD said an 80% surge in second-quarter net profit to 4.74 billion dirhams was partly driven by an asset sale and foreign exchange gains.

The results reinforced signs that top banks in the UAE are managing to withstand strains from a sluggish economy and a property downturn in Dubai.
