The attack was more of a minor irritant than a drastic change in the security scenario, according to Vijay Valecha, Chief Investment Officer, Century Financial. The security infrastructure in UAE is pretty robust and this has prevented these kinds of attacks so far, he said. "Due to this reason, it is improbable that investor sentiment will be impacted." Dubai"s main share index (.DFMGI) dipped 0.1%, hit by a 1.4% fall in blue-chip developer Emaar Properties (EMAR.DU) and a 1.4% decline in budget airliner Air Arabia (AIRA.DU). Saudi Arabia"s benchmark index (.TASI) gained 0.2%, holding steady at its highest in over 15 years, helped by a 4.4% rise in Riyad Bank (1010.SE). Red Sea International (4230.SE) surged 10%, the top gainer on the index, following a contract worth more than 60 million riyals ($15.99 million). Saudi shares are supported by strong oil prices and the market was unaffected by the drone attacks on the UAE, said Eman AlAyyaf, CEO of EA Trading.
