The IBEX 35 is Spain’s benchmark stock market index. It tracks the performance of the 35 most liquid companies listed on the Bolsa de Madrid. As a capitalization-weighted index, companies with larger market values have a greater impact on its movements.

What Is the IBEX 35?

The IBEX 35 represents the Spanish stock market’s overall performance. It includes top companies across industries like banking, telecommunications, and energy. Managed by Bolsas y Mercados Españoles (BME), it serves as a key indicator of Spain’s economic health.

The IBEX 35 index originated in 1992, but its base level of 3000 was calculated using data from December 1989.

The Sociedad de Bolsas calculates the index in real-time (European time zone), denominates it in euros, and weights stocks by market capitalization.

During Spain’s period of robust economic growth, from 2000 to 2007, the index outperformed many major Western exchanges, including the FTSE 100 and CAC 40.

How Is the IBEX 35 Calculated?

The following formula is used to determine the index value (represented here as I) of the IBEX 35 index:

At the calculation moment (t), J acts as a coefficient to adjust the index for capital increases or other corporate actions, ensuring continuity. Cap represents the free float market capitalization of a particular listing.

Modifying the formula allows for adjustments in index structure, such as temporarily suspending companies awaiting news.

The market capitalisation method used by the IBEX 35 is free-float. This indicates that a company’s index weighting is based solely on shares that are available to the public. To make sure it appropriately represents the market, the index is examined twice a year.
