DUBAI - An overnight rise in crude oil prices to a fresh five-month peak helped to push the Riyadh stock index slightly higher on Thursday while Qatar secured its third straight day of gains.

The Saudi index .TASI edged up by 0.1 percent as all but two of the 14 listed petrochemical producers rose as Brent contracts LCOc1 traded around $56 a barrel.

Yanbu National Petrochemical 2290.SE added 0.9 percent. Shares in the large-cap producer have been active for four sessions, and one Riyadh-based analyst told Reuters that investors have been building positions in "relatively safer petrochemical stocks" because of the recent climb in the oil price.

Shares of media conglomerate Saudi Research and Marketing 4210.SE jumped 4.6 percent after it signed a contract with Bloomberg for an exclusive license to launch a Bloomberg Arab channel. The contract is for 10 years with an annual license cost of 33.8 million riyals.

"Local retail investors depend heavily on financial TV programmes for news and analysis, like Alarbiya and CNBC Arabia, so to add Bloomberg in Arabic will mean SRMG is set to benefit from advertising revenue," said a Saudi-based investment advisor.

In Qatar, the index .QSI managed to build positive momentum in the final hour of trade, and added 0.2 percent. Oil drilling service provider Gulf International Services GISS.QA climbed 3.8 percent and maritime and logistics company Qatar Navigation QNNC.QA added 0.3 percent.

Shares in the index are now up 1 percent in three days thanks to local funds ratcheting up their buying and foreign funds slightly easing their selling of Qatari shares, bourse data showed.

Bourses in the United Arab Emirates, Kuwait, Bahrain and Egypt were closed because of the Islamic New Year holiday.
