The Athens Stock Exchange started trading in 1876. The Athens Stock Exchange is a subsidiary of Hellenic Exchanges S.A., whose shares are listed in ATHEX. In August 1999, the derivatives market started trading, and in 2002 the Athens Stock Exchange and the Athens Derivatives Exchange merged to form the Athens Stock Exchange.
Until 2007, the exchange was located on Sofocleous Street, in the central business district of Athens. For this reason the Exchange and Sofocleous St became synonymous with each other. It is now located in its new headquarters at 110 Athinon Street, also called Kavalas Street. The exchange's trading hours are from 10:00am to 05:20pm Monday to Friday, and is closed on Saturdays, Sundays and holidays declared by the Exchange in advance.
