Alpha ETF: For Both Novice and Experienced Stock Market Investors – Article on Liberal.gr

An ETF (Exchange-Traded Fund) is essentially a mutual fund, meaning an investment basket that holds shares of the 25 largest listed companies on the Athens Stock Exchange (ASE), such as National Bank of Greece, Eurobank, Mytilineos, Coca-Cola HBC, Alpha Bank, and others. However, unlike traditional mutual funds, it trades like a single stock on the exchange.
The structure of the ALPHA ETF fully replicates the composition of the ASE Large-Cap Index, ensuring that its performance closely tracks that of the index itself.
