Amsterdam’s AEX index fell 0.5% to 1,109 points shortly after trading began on 1 October, the first session of the final quarter of 2026. The MidKap also lost 0.5%, reaching 1,076 points. The early dip followed a rise of more than 15% for the AEX over the first nine months of the year. Frankfurt, Paris and London were also lower, with losses of up to 1.2%. [1]

ANP linked the cautious mood partly to a slight rise in oil prices. Chip shares provided a counterweight: Besi, ASML and ASMI led the AEX with gains of up to 2.4% after US chipmaker Micron Technology issued an upbeat outlook following Wednesday’s Wall Street close. Micron reported historically high profit margins for the past quarter, though it said it expected them to ease somewhat. [1]
