European stocks slipped on Thursday, extending a recent run of losses as technology shares sold off for a second straight session. The pan-European STOXX 600 index fell 0.6%, dragged lower by a sharp decline in semiconductor stocks and growing unease over rising tensions in the Middle East.
The sell-off was led by the technology sector, which has been under pressure this week as investors question whether the high-flying chip industry has gotten ahead of itself. The STOXX Europe 600 Technology Index tumbled 2.3%, with some of the region's biggest names taking the hardest hits.
Semiconductor stocks slide despite strong outlooks
Dutch chip-equipment maker ASML, one of Europe's most valuable tech companies, fell more than 4%. ASMI, another Dutch semiconductor firm, also dropped over 4%, while French chip materials supplier Soitec lost 3.6%. The declines came even after both ASML and Taiwan Semiconductor Manufacturing Company (TSMC) — the world's largest contract chipmaker — issued strong outlooks earlier this week.
That apparent contradiction — good news from companies, but falling stock prices — is a classic sign that investors are rethinking the prices they are willing to pay for future earnings. After a long rally in chip stocks, many now look expensive relative to their profit expectations. When that happens, even positive updates can fail to support share prices as traders take profits or move money elsewhere.
The sell-off in Europe mirrors a broader pullback in global tech stocks. In Asia, Taiwan's chip stocks tumbled earlier this week, with TSMC dropping 7% despite reporting record profits. That weakness has now spread to European markets, as investors reassess the AI-driven rally that lifted semiconductor shares to multi-year highs.
Middle East tensions add to market jitters
Adding to the cautious mood, rising geopolitical tensions in the Middle East pushed oil prices higher. Crude oil edged up as investors weighed the risk of supply disruptions in a region that produces about a third of the world's oil. Higher energy costs can feed into inflation, which complicates the outlook for central bank policy.
For European markets, the combination of tech weakness and geopolitical uncertainty has created a risk-off environment. Investors are rotating out of high-growth sectors like semiconductors and into more defensive areas, such as energy stocks, which benefit from higher oil prices.
The Middle East conflict has already had ripple effects on European tourism and luxury spending. Burberry, for example, has flagged that the conflict is hitting travel to Europe from key markets like the US and China, adding to the challenges facing the luxury goods sector.
What it means for everyday investors
For ordinary investors, the recent tech sell-off is a reminder that even the most exciting sectors can go through rough patches. Semiconductor stocks have been among the best performers this year, driven by enthusiasm around artificial intelligence and the chips needed to power it. But when prices rise faster than earnings, the market often corrects.
That doesn't necessarily mean the long-term story is broken. ASML and TSMC are still reporting strong demand, and AI investment is expected to continue growing. But in the short term, valuations matter. When a stock's price gets too far ahead of its earnings, it becomes vulnerable to profit-taking.
Investors should also keep an eye on oil prices and Middle East developments. A sustained rise in crude could push up inflation, which might force central banks like the European Central Bank to keep interest rates higher for longer. That would be a headwind for stocks broadly, especially for growth companies that rely on cheap borrowing.
For now, the message from the market is clear: after a strong run, tech stocks are taking a breather, and investors are watching for the next catalyst — whether that's earnings, central bank policy, or geopolitical events.
