Ackermans & van Haaren shares traded modestly lower on Euronext Brussels on 06/01/2026, even as the Bel20 index closed with a small gain of around 0.5 percent, placing the diversified investment group among the weaker performers in the Belgian blue-chip benchmark for the day, according to a market recap from De AandeelHouder as of 06/01/2026.
