The Tadawul All Share Index (TASI) closed the final session of the digest week at 10,392.97 on Oct. 1, 2026, down 47.67 points, or 0.46%, from the prior session's close of 10,440.64. The session moved between a low of 10,357.97 and a high of 10,453.92, according to Saudi Exchange data.
The week's main regulatory development came from the Capital Market Authority, which issued draft provisions requiring Tadawul-listed companies to hold earnings calls twice a year. Under the draft, calls must take place within five business days of the release of financial results, with supporting materials posted immediately on company websites, AGBI reported on Sept. 30.
Corporate activity was led by Arabian Drilling, which signed a four-year rig contract worth approximately SAR 2 billion with Khafji Joint Operations, lifting backlog to a record SAR 18 billion. Elsewhere, the Ninth Commercial Circuit of the Riyadh Commercial Court initiated liquidation proceedings for United Cooperative Assurance (UCA, 8190), following the Insurance Authority's suspension of its underwriting activity earlier in the month. Saudi Exchange also published its Q3 2026 index maintenance, with Chemanol, Armah Sports, and Ladun Investment set to join TASI effective Oct. 4.
