Euronext Lisbon is a thriving exchange with a rich, cultural history that features a diverse array of corporate equities, bonds, and exchange traded products.


On 1 January 1769, the Lisbon Stock Exchange—or more precisely, the Business Man's Assembly—was installed in the small tower on the east side of the Praça do Comércio, along with the most important organizations linked to the capital's trade. Almost one century later, the Porto Stock Exchange was created. The Lisbon and Porto Exchanges merged in 1999 to create the Bolsa de Valores de Lisboa e Porto. It became part of Euronext’s family of exchanges in 2002.

PSI 20 Index

The PSI 20 is the Portuguese benchmark index, which reflects the price evolution of the 20 largest and most liquid share issues of all the companies listed on the Portuguese main market. The PSI 20 was launched with a double purpose: to act as a benchmark for the national equity market, and to act as the underlying for futures and options contracts.

Regulatory bodies

In collaboration with the Portuguese Securities Code and regulations from Comissão do Mercado de Valores Mobilários (CMVM), the Portuguese Decree, Law no. 357-C/2007, (31 October 2007) governs the Euronext regulated markets and multilateral trading facilities, market operators, all companies with related activities in Portugal, systemic internalisers, and financial intermediaries. The CMVM is an independent public authority that monitors markets and market participants, public offerings and collective investment undertakings. Consultation with the CMVM, followed by prior authorization (in the form of an ordinance) from the Portuguese Minister of Finance is required to create a regulated market company.

The Portuguese Securities Market Commission (CMVM), the regulatory authority for Euronext Lisbon, is in charge of supervising and regulating financial markets. Within its supervision role, CMVM follows market activity, monitors compliance with laws and regulations, files registries, develops inspections, imposes sanctions, and issues ordinances and specific recommendations.
