The largest companies in Spain have an important influence on the country and the world’s economy. The top 35 publicly traded companies of Spain, making up the IBEX 35 index, are presented here together with their activities, logos, sectors and useful links.
In Spain, companies must be, or become, Sociedad Anónima, abbreviated S.A., meaning “anonymous corporations”, to get listed on the Madrid Stock Exchange (Bolsa de Madrid). Even though they must abide by the rules of the Comisión Nacional del Mercado de Valores (CNMV), companies that become publicly listed are then entitled to receive capital from investors who buy their shares.
The IBEX 35 Index
To facilitate the comprehension of the evolution of the Spanish stock market and the broader economy, the stocks of the 35 largest companies by market capitalization are aggregated in the IBEX 35 index or CAC, (standing for Índice Bursátil Español) which is the benchmark stock market index of Spain.
Reviewed twice a year, the IBEX 35 is a capitalization-weighted index, in which the stocks of the 35 component companies are weighted according to the total market value of their outstanding shares. The largest companies by market capitalization thus weigh more in the index than smaller ones.
The real-time quotation of the IBEX 35 index can be followed with convenient graphical tools from a number of sources, including the Madrid Stock Exchange, Google Finance, Yahoo Finance, Bloomberg, etc.
