Saudi Exchange (Tadawul)

The Saudi Exchange (Tadawul) is Saudi Arabia's primary securities exchange and the core venue for local equity price discovery. Operationally, it's one of the exchanges most affected by a non-standard trading week: the Saudi market historically traded Sunday–Thursday, though it has aligned more closely with international norms in recent years. The TASI (Tadawul All Share Index) is the headline benchmark.

For global traders, Tadawul matters because Saudi Arabia's economy is deeply tied to oil and energy, and the exchange hosts Saudi Aramco—the world's most valuable listed company. Movements in Tadawul can signal shifts in regional risk sentiment and energy-market expectations before Western markets open.

Trading Nuances: Be mindful of the trading week structure and Riyadh time zone (AST, UTC+3) when planning your session. Saudi holidays follow the Islamic calendar, which means dates shift year to year—always check the holiday calendar. Liquidity tends to concentrate mid-session; the open and close can see wider spreads. If you trade energy or Middle Eastern themes, aligning your watchlist with Tadawul's active hours provides better context for price moves.
