BEL 20 falls 0.4% as technology stocks and US elections weigh

The BEL 20 came under pressure in Brussels on Tuesday, falling about 0.4% to 5,854 points in morning trading. The move followed a 0.61% advance on Monday, when the index closed at 5,876.76 points near its recent high.

Technology weakness weighs on Europe

According to ABM Financial News, published by Beursduivel, the session was shaped by the US midterm elections and renewed pressure on technology shares. Melexis, Umicore and Sofina were among the weakest BEL 20 constituents, with losses of between 1.5% and 2%, while only UCB and Aedifica were reported higher within the blue-chip index.

The backdrop remained cautious after the Nasdaq fell 1.07% on Monday. Investors continued to question the return on large artificial-intelligence investments, while Apple's outlook added to the pressure after the company warned of lower holiday-quarter gross margins because of higher memory-chip costs. Apple's expected services-revenue growth also disappointed, according to ABM Financial News via Beursduivel.

Midterm vote remains in focus

Investors are also awaiting the outcome of the US midterm elections. Market participants are assessing whether a possible shift in control of Congress could constrain President Donald Trump's fiscal and tariff agenda. That uncertainty has encouraged a more defensive stance in European equities, even as oil prices recovered about 2% on Tuesday after their sharp decline the previous day.

The BEL 20's decline therefore reflects a combination of external technology weakness and political uncertainty rather than a single company-specific catalyst. The index remains close to its recent high, but the session's breadth was weak, with most constituents moving lower. Further developments in US voting and technology stocks are likely to remain important for the direction of the Brussels benchmark. More BEL 20 coverage
