What is the name of the stock index that tracks 50 major Eurozone companies?

The stock index that tracks 50 major Eurozone companies is the EURO STOXX 50. It is a blue-chip index designed to represent leading companies from countries that use the euro, with constituents selected largely by free-float market capitalization.

STOXX, the index provider, organizes the EURO STOXX 50 across major economic sectors rather than concentrating it in one industry. Its constituents can include companies from countries such as France, Germany, the Netherlands, Spain, Italy, and Belgium. The membership is reviewed periodically, so the exact companies can change.

The most important distinction is between the EURO STOXX 50 and the STOXX Europe 50. The former is limited to the Eurozone, while the latter covers large companies from a broader set of European markets, including countries outside the euro area.

It is also different from Germany’s DAX and Britain’s FTSE 100, which are national-market indexes. The STOXX Europe 600 is broader still, covering hundreds of European companies rather than 50 Eurozone blue chips. Futures and options on the EURO STOXX 50 are widely traded through Eurex.
