JEDDAH: A break in Brent crude prices over $50 a barrel failed to support Saudi Arabia’s Tadawul All-Share Index on Thursday, but helped carry Dubai’s index higher for a fourth session. Other markets were mixed.

The index failed to hold on to earlier gains as investors booked profits, snapping two days of gains.

Although petrochemical shares remained resilient, with the sub-index advancing 0.3 percent, it closed 49 points below its intra-day high, a sign that investors lack belief in a sustained rally.

Speculative shares, favored by local day traders and which are usually heavily traded, dropped. Tourism company Altayyar Travel Group fell 2.8 percent while insurer Alinma Tokio Marine tumbled 3.1 percent.
