The Dubai bourse appears to be moving in close correlation to Emaar, with the property developer losing 0.42 per cent yesterday, compared to the index's 0.39 per cent fall. Over the past four weeks, this pair have moved in different directions on only five occasions and two of these were when Emaar closed flat, so despite the huge volumes in small-cap stocks and mega gains in Arabtec, it seems the immediate fate of the Dubai bourse rests with its market leader.
