OPEC+ oil producers considering lowering their output target at a meeting on Oct. 5. The Saudi index rose for a fourth consecutive session, while the Qatar bourse finished lower. The kingdom expects to post a surplus of 0.2% of GDP in 2023, a drop from an expected surplus of 2.3% this year. Egypt’s blue-chip index fell 1%, as most of the stocks on the index were in negative territory.

The Qatari index dropped 1.2%, weighed down by a 1.7% fall in petrochemical maker Industries Qatar. . . .
