The CEO of the ASE, Jalil Tarif, said that the Free Float market capitalization weighted index approach has been adopted by many international stock exchanges and index providers institutions such as S&XP, FTSE Group, and Dow Jones Indexes and STOXX. This index includes the same 100 listed companies at the ASE included in the index weighted by market capitalization.This index reflects the market performance, and it also decreases the effect of the big companies in terms of market capitalization on the index movement.
Besides, it gives a chance to small and medium companies to affect the index movement.
The weight of each company in the new index determined by the market capitalization of its free float shares and the weight of a single company is capped by up to (10%).
