The Colombia Stock Exchange, also known as the CSE, is the country’s main market and started up in 2001 when the three existing bourses - Bolsa de Bogotà, Bolsa de Medellin and Bolsa de Occidente, were merged.
In January 2003, Infoval (Information system for the evaluation of investments) was started up. It calculates and publishes prices, margins and indexes to make the market more transparent and efficient.
At the end of 2005, the exchange listed 116 equities with a total capitalization value of US$50.0 billion.
The biggest listed companies, by capitalization value, are Cemargos, Bcolombia, Bavaria, Grupo Aval, Suraminv, Inveragos, Bogotà Chocolates, Isa and Promigas.

Products traded include ordinary shares and warrants, preference shares, debt instruments such as loans and bonds; monetario with bank acceptance and government securities.
All transactions come under the strict control of the Banks and Companies Supervision Authority and the CSE.
Fiscally, dividend pay-outs are tax-free, given that the relevant tax is applied, or exempted, at source, ie. payable by the listed company.
The CSE has an electronic trading system known as MEC (Colombian Electronc Market) based on best price and time of entry of orders.
For certain types of securities, however, the “call over” system is still in use.
Transactions are compensated by a clearing house that oversees and clears all transactions made on the market, balancing the payables and receivables of all the brokers and carrying out compensation accordingly.
