Shares in Arabtec jumped 13.6 percent to AED4.86 on Tuesday, accounting for most of the turnover on the Dubai bourse, which gained 3.4 percent. Analysts' estimates suggest Arabtec is once again well above fair value; the median target price of eight analysts surveyed by Reuters is AED3.68.
However, the stock has regained the interest of retail investors, who are hoping for strong second-quarter earnings at the company and possibly a decision by major shareholder Aabar Investments to raise its stake. So it may remain strong.
Arabtec's leap helped Dubai trigger an inverse head and shoulders pattern formed by the late June and early July lows, and pointing back up to May's multi-year peak of 5,407 points, which is strong resistance.
