The Athens General Index climbed 0.7% to 2,587.84 points on Monday, marking a strong start to the month and the week.
The benchmark is now within striking distance of the psychological 2,600 level, buoyed by positive investor sentiment and robust corporate performance.
The rally reflects sustained buying interest in blue-chip names, particularly as companies report solid first-half results.
Market participants are focusing on earnings resilience, with dividend-paying stocks attracting particular attention amid the broader upward trend.
This momentum aligns with a broader regional recovery narrative, where Greek equities have outperformed many European peers.
The index's approach to 2,600 represents a key technical hurdle; a decisive break above this level could open the door for further gains in the coming weeks.
Investors will now look to upcoming central bank decisions for further direction.
