The BMV calculates 13 indices of stock prices. Each index can be used as an underlying value for derivative products listed on specialized markets. The main benchmark stock index is called the IPC, which stands for Índice de Precios y Cotizaciones, and is the broadest indicator of the BMV's overall performance. It is made up of a balanced weighted selection of shares that are representative of all the shares listed on the exchange from various sectors across the economy, and is revised twice a year. Weight is determined by market capitalization. The IPC's value is related to the previous day's value, rather than the base date of October 30, 1978. Since February 2009 the IPC index has included BMV's own A shares. Indice Mexico (INMEX) is a market capitalization weighted index of 20 to 25 of the BMV's most highly marketable issuers, using their most representative series. The sample is limited to issuers with a minimum market value of $100 million and is revised every six months. The weighting cannot be greater than 10% at the start of each calculation period.
