Largest Listed Companies in Greece by Market Capitalization
Founded by government decree in 1876 and operational since 1880, the Athens Stock Exchange — known as ATHEX — lists over 200 companies and remains the primary equity market in Greece. Now majority-owned by Euronext, ATHEX trades exclusively in euros and is regulated by the Hellenic Capital Market Commission.
The FTSE/ATHEX Large Cap Index, a joint venture between FTSE Russell and ATHEX since 1999, tracks the 25 largest qualifying blue-chip stocks on the exchange. Banking dominates the top of the market, but several other sectors carry significant weight:
- Banking: Eurobank Ergasias (founded 1924), National Bank of Greece, Alpha Bank, and Piraeus Financial Holdings (listed on ATHEX since 1918).
- Telecommunications: OTE Group, the largest telecom provider in Greece and Southeast Europe, with Deutsche Telekom as its majority shareholder.
- Energy & Metals: METLEN (formerly Mytilineos), active in thermal and renewable energy as well as alumina and aluminum production.
- Utilities: Public Power Corporation (PPC), founded in 1950, delivering electricity across Greece.
- Gaming: OPAP, established in 1958, holds a monopoly in the Greek gaming market.
- Construction Materials: Titan Cement International, which opened its first cement plant in 1902.
All Greek stocks on ATHEX trade in EUR, and the exchange operates five markets including a regulated securities market, a derivatives market, and a carbon market for EU emission allowances.
