Athens Exchange shares edged higher in quiet trading, as investors weighed ongoing geopolitical tensions in the Middle East and prepared for the implementation of MSCI index rebalancing adjustments at the close of the session.
The domestic market closed out August on a positive note, maintaining a cautious stance amid thin turnover. Market participants navigated a backdrop of international nervousness, driven closely by energy market fluctuations following recent military strikes in the Middle East.
MSCI Rebalancing Focuses Attention on Motor Oil and Κρι Κρι
A primary driver for the session was the scheduled application of the MSCI index rebalancing, which took effect at the close of trading. The adjustment period brought renewed focus to specific large- and mid-cap equities. Motor Oil returned to the MSCI Standard Greece index, while Κρι Κρι secured entry into the Greece Small Cap index.
Trading volume heavily concentrated around these index shifts. Meanwhile, mid-cap constituent Κρι Κρι recorded transactions of approximately 740 χιλ. ευρώ, posting a 1.2% gain to reach 32.8ευρώ.
Banking Sector and Large-Cap Performance
Systemic lenders provided the primary support for the General Index, which settled around the 2.690 μονάδες mark with a 0.4% increase. The banking sub-index climbed 0.7% to reach 3.153 μονάδες. Individual gains across major banks included ΕΤΕ rising 1.6%, Piraeus advancing between 0.7% and 1.38% depending on the intraday snapshot, Eurobank adding 0.4%, and Alpha Bank ticking up 0.2%.
Beyond the financial sector, selective buying lifted several large-cap components. Piraeus-alongside the Piraeus Port Authority (ΟΛΠ)-led early morning gains alongside OTE, which rose 1.17%. Additional support came from Aegean Airlines with a 1% increase and Titan Cement gaining 1.2%. Conversely, downward pressure affected select names including Metlen and Allwyn, both sliding roughly 1%.
Broader Market Sentiment and Monthly Closing
The cautious tone across the Athens exchange reflected broader European market trends and international anxieties. Investors assessed the potential fallout from renewed military clashes in the Middle East following reports of U.S. strikes and retaliatory actions, which pushed crude oil prices higher.

Despite the low liquidity and selective selling that left 62 stocks declining against 48 advancers, the market wrapped up August having successfully completed six positive weeks. Analysts and traders now look ahead to September trading conditions following the completion of the MSCI rebalancing and the digestion of regional geopolitical developments.
