Top 10 TASI Stocks by Market Cap — June 2026

Saudi Aramco dominates the index to a degree that has no equivalent in any other major stock exchange globally.

What Each Company Does and Why It Matters

The top 10 spans six sectors — energy, banking, materials, telecom, utilities, and healthcare — each a distinct pillar of Vision 2030.

Saudi Aramco (2222) — Energy

Saudi Aramco is the world's largest oil-producing company and the single largest constituent of TASI. It accounts for approximately 67% of total TASI market cap, meaning that on any given day, Aramco's share price movement is the single most powerful force on the entire index. Aramco reported net profits of $106.2 billion for FY2024 and offers one of the highest dividend yields of any company in the top 10. It issued a $4 billion bond in early 2026, signalling continued strength in global capital access.

Key fact: Because Aramco represents ~67% of TASI, its correlation with oil prices means TASI behaves more like a commodity index than a diversified equity index during oil price shocks. This is the single most important fact for any GCC investor considering TASI exposure.

Al Rajhi Bank (1120) — Islamic Banking

Al Rajhi Bank is the world's largest Islamic bank by assets and the most widely held Saudi bank stock by retail investors across the GCC. It operates under full Sharia compliance across retail and corporate banking, home finance, and investment products. Analysts forecast earnings growth of approximately 11% per annum through 2026–2028, with a return on equity projected at 22% in three years. It pays a consistent dividend currently yielding approximately 3%.

Saudi National Bank — SNB (1180) — Banking

SNB is Saudi Arabia's largest bank by total assets following its merger with Samba Financial Group. It serves both retail and wholesale clients across Saudi Arabia and internationally. SNB drew significant global attention in 2023 following its investment in Credit Suisse; however, that episode is now resolved and the bank has returned to stable operations and consistent dividend payments.

SABIC (2010) — Petrochemicals

Saudi Basic Industries Corporation is one of the world's largest petrochemical companies, producing plastics, chemicals, fertilisers, and metals sold to customers in more than 50 countries. It is majority-owned by Saudi Aramco and shares close correlation with both oil prices and global manufacturing demand cycles.

Ma'aden (1211) — Mining

Saudi Arabian Mining Company is the Kingdom's primary mining company and a key Vision 2030 diversification vehicle. Ma'aden mines phosphate, gold, bauxite, and other minerals, and is expanding rapidly as Saudi Arabia develops its non-oil resources.

STC (7010) — Telecommunications

Saudi Telecom Company is the Kingdom's largest telecom operator and a significant 5G network builder. STC reported a market cap of approximately $64 billion and net profits of $6.6 billion. It offers a dividend yield of approximately 10%, among the highest of any major Saudi company, driven by strong free cash flow from its dominant domestic telecom position.

ACWA Power (2082) — Utilities / Renewables

ACWA Power is one of the top contributors to TASI's gains in 2024, with a +295 point contribution to the index per Argaam data. It develops, operates, and co-invests in power generation and water desalination plants across Saudi Arabia and internationally, making it a direct Vision 2030 play on renewable energy and water security.

What Aramco's Dominance Means for TASI Investors

No other major global index is as concentrated in a single stock as TASI is in Aramco. This creates a specific risk GCC investors must understand.

The S&P 500's largest constituent (Apple) represents approximately 7% of the index. Aramco represents approximately 67% of TASI. This means the TASI index effectively behaves as a direct proxy for Saudi Aramco's share price and, by extension, for global oil demand and Brent crude prices. When oil falls sharply, as it did in April 2025 when Brent dropped below $60/barrel, Aramco loses value and TASI falls accordingly, even if every other sector is performing well.
