The Tadawul All-Share Index (تداول, TASI) is the leading stock market index in Saudi Arabia. It comprises all companies listed on the Tadawul Stock Exchange.

Index
The Tadawul All-Share Index is a price index in which all stock corporations on the Tadawul Stock Exchange are listed. It reflects the development of the entire Saudi Arabian stock market. The index level is determined exclusively based on share prices and is only adjusted for income from subscription rights and special payments. The weighting is based on the market capitalization of the listed companies, with the weighting of large constituents being capped. Corporate actions such as share splits have no (distorting) influence on the index. The calculation is updated continuously during trading hours.

The index was launched on February 27, 1985, under the name National Center for Financial and Economic Information Index (NCFEI Index). The base value was initially 100 points. On January 23, 1998, the index was multiplied by a factor of 10, and the 1985 base value was set at 1,000 points.
