The Saudi Exchange is the primary listing venue for Saudi Aramco, one of the world’s largest companies by market capitalization.
Saudi Aramco began trading on the Saudi Exchange, also called Tadawul, in December 2019. Tadawul is Saudi Arabia’s principal stock exchange and the largest in the Middle East by several commonly used measures, including listed-company value.
The exchange operates in Riyadh and is regulated by the Capital Market Authority of Saudi Arabia. Its benchmark index is the Tadawul All Share Index, often abbreviated TASI, which tracks broad performance across the Saudi equity market.
A company’s primary listing is important because it identifies the main market where its shares are traded and regulated. Market-cap comparisons can include companies listed in different countries, so currency conversion and share-class treatment may affect the ordering.
