The Abu Dhabi and Dubai indexes hit 24-week closing highs, but some of the latter's early-session gains are eroded as it again fails to break above 2,000 points.
Dubai's benchmark climbs 2.1 per cent to 1,960 points, its highest finish since December 14, with Dubai Financial Market surging 9.4 per cent as investors bet the market's rising volumes will translate into bigger profits.
Emaar Properties rises 3.8 per cent and Arabtec adds 2.4 per cent. Dubai Financial Market, Emaar and Arabtec together account for more than half of trading on the benchmark.
"For long-term, value investors Dubai is cheap with many stocks trading below their book value and so if you believe in the long-term story of Dubai there's a good opportunity to buy," says Shakeel Sarwar, Sico investment bank head of asset management.
Abu Dhabi's index also ends higher, rising 1.5 per cent to 2,725 points, its highest finish since December 14.
"We are part of the global equity market and good news, particularly from the U.S., has lifted Gulf stocks, with buyers risk appetite for equities rising since March," says Sanyalaksna Manibhandu, Emaar Saudi Financial Services head of research.
Emirates Telecommunications Corp (Etisalat) climbs 2.8 per cent.
