TASI Closes 0.3% Lower; ACWA Power Slips to May Low

Saudi Arabia's benchmark Tadawul All Share Index (TASI) ended the session on Sunday, 20 September 2026, down about 0.3% at roughly 10,750 points, reflecting cautious trading across the market. Total turnover for the day reached around SAR 2.6 billion.

Among the notable movers, ACWA Power Co. shares fell by about 2.8% to 3.0%, closing near SAR 175.00 — the company's lowest closing level since May 2026.

The softer performance in the index and in ACWA Power came against a backdrop of subdued sentiment following security alerts issued around the capital Riyadh. These included warnings of potential danger near King Khalid International Airport, along with reports of flames and smoke observed close to the airport area.

How trading works

Trading in TASI stocks, including ACWA Power, is carried out through the Saudi Exchange (Tadawul) via licensed brokers and trading platforms connected to the exchange. Retail and institutional investors access the market through their brokerage accounts licensed by the Capital Market Authority.

Standard trading hours run from 10:00 to 15:00, Sunday to Thursday, Riyadh time, with exchange fees and broker commissions applied as set by the Saudi Exchange and the Capital Market Authority.

For residents and expats who follow the local market, single-session moves of this scale are common and reflect day-to-day sentiment rather than any single trend. Investors are generally advised to focus on their longer-term plans and to review market updates through their licensed brokerage accounts.
