Greek stocks are poised for a significant uplift as the Athens Stock Exchange officially transitions to developed market indices on September 21, leaving behind its advanced emerging-market classification. This upgrade, effective after the rebalancing of FTSE Russell and Stoxx indices on September 18, is expected to attract substantial capital inflows, with JPMorgan estimating total flows of up to $2.8 billion from European index rebalancing. Banks are anticipated to be the primary beneficiaries, absorbing the largest share of this capital due to their high weightings in the new indices. JPMorgan has also raised its targets for the four systemic Greek banks: Alpha Bank to €5.50, Piraeus Bank to €12.30, Eurobank to €5.40, and National Bank of Greece to €19.30.
