How is the IBEX 35 Calculated?

The IBEX 35 is calculated using a weighted average market capitalization methodology. This means that the index is calculated based on the market value of each company included in the index, with larger companies having a greater influence on the index’s performance.

To calculate the index, the following steps are taken:

First, the market capitalization of each company included in the index is determined. Market capitalization is calculated by multiplying the current share price of a company by the total number of shares outstanding.
Next, the weights of each stock are determined based on their market capitalization. The weight of each stock is calculated by dividing its market capitalization by the total market capitalization of all the stocks in the index.
Once the weights are determined, the index is calculated as the weighted average of the stock prices. This means that the price of each stock is multiplied by its weight and then summed up to get the final index value.

The IBEX 35 is calculated in real-time throughout the trading session. This means that as the prices of the constituent stocks change, the index is updated to reflect these changes.
