The Belgrade Stock Exchange (BELEX) is the only stock exchange of Serbia. Its operations are overseen by the Securities Commission and the exchange is headquartered in Belgrade, the capital and largest city of Serbia, which generally plays an important role in the global economic system. The roots of the exchange go back to 1895, when the first transactions took place in a hotel by the river Sava. As such it was one of the oldest exchanges in Europe. BELEX lists 29 companies, has a market cap of € 4.5 billion and is a full member of the Federation of Euro-Asian Stock Exchanges (FEAS).

Among the listings are well-known and actively traded companies such as Energoprojekt holding, NIS, Sojaprotein, Komercijalna banka and Messer Tehnogas Beograd. BELEX manages 2 indices. The BELEX15 is the leading blue-chip index which only tracks the performance of the most liquid common shares on the regulated market. The more broad BELEXline index is a free‐float market capitalization weighted index that tracks the performance of a bigger basket of shares for which there is no upper limit for the number of constituents. Both indices are commonly used by traders and investors.
