  • Greek Stocks Outperform Nasdaq 100 Over Last 5 Years Amid Banking Recovery
    May 19, 2026, 1:05 AM EDT. Greek stocks have surged approximately 146% over the past five years, outpacing the Nasdaq 100's 116% return, marking a dramatic turnaround from their crisis lows. The Athens Composite Index rebounded from a 90% collapse during the debt crisis, driven chiefly by the recovery of Greek banks. These lenders, previously burdened by non-performing loans as high as 47%, benefited from the Hellenic Asset Protection Scheme (Hercules), allowing them to offload €57 billion of bad debts. By 2025, Greece's four largest banks posted combined net profits near €5 billion and increased shareholder payouts via dividends and buybacks. This recovery has restored banks' roles in financing the Greek economy, highlighting a notable regional equity revival amid a slow European market.
