Calculation of the Ibex 35 Index
The Ibex 35 index is a capitalization-weighted index, which means that the weight of each company in the index is proportional to its market capitalization. The market capitalization is calculated by multiplying the number of outstanding shares of a company by its current market price. The formula for calculating the index is as follows:
Ibex 35 = (Σ (Market Capitalization of Constituent Company i / Total Market Capitalization) x Base Value)
The index’s base value is set at 3,000 points, which means that if the total market capitalization of the 35 companies increases or decreases, the index value will also increase or decrease proportionally.
