There are two securities exchanges in Mexico: the Mexican Stock Exchange (Bolsa Mexicana de Valores; www.bmv.com.mx and, as of 25 July 2018, the Institutional Stock Exchange (Bolsa Institucional de Valores; www.biva.mx). Securities of both Mexican and foreign issuers can be listed and traded on both Stock Exchanges. The Mexican equity market is highly concentrated and the top five companies by market value make up approximately 49% of the index. The index is weighted heavily in favor of export companies as exports account for approximately one-third of Mexico’s gross domestic product.

Recently public M&A activity has slowed and only one hostile takeover has been attempted, which failed after a Supreme Court of Justice case. This was the proposed acquisition of control by Grupo Mexico of Grupo del Pacífico in which the Supreme Court of Justice ruled that publicly listed companies may adopt necessary – albeit not absolute – corporate measures to deter hostile takeovers.
