Semiconductor ETF Sheds $3.3 Trillion as Chinese AI Rivalry and Geopolitical Jolts Ignite a Bear Market

The champagne has turned sour for chip investors. The VanEck Semiconductor UCITS ETF closed at €92.15 on Friday, capping a weekly rout of 8.83%—its third losing week in four—as the Philadelphia Semiconductor Index officially crossed into bear territory. Since its late-June peak, the benchmark has collapsed more than 20%, wiping out roughly $3.3 trillion in market value from global semiconductor stocks, including Asian heavyweights Samsung Electronics and SK Hynix.
Technicians point to a textbook head-and-shoulders top on the Philadelphia index, which shattered the psychologically important 12,000-point threshold on Thursday with a 4.3% plunge. The breakdown follows a parabolic rally that saw the index soar 105% from its March low to the June high, leaving the sector vulnerable to profit-taking. “The decline reflects profit-taking and a growing skepticism about the sustainability of AI investments,” said Toni Meadows, chief investment officer at BRI Wealth Management.
The pain is concentrated in the very segment that fueled the rally: memory chips. Micron Technology, Samsung, and SK Hynix have dragged the entire storage category into a bear market, with dozens of individual names now trading at least 20% below their June 22 levels. Equipment makers have not been spared either: Applied Materials and Lam Research each lost more than 4% on Friday. Yet Nvidia, the poster child of the AI trade, remains nearly unchanged from that June reference date—a telling sign that the selloff is happening despite, not because of, the market leader.
Two fresh catalysts intensified the slide on Friday. China’s AI startup Moonshot unveiled Kimi K3 at the World Artificial Intelligence Conference in Shanghai, describing it as one of the largest open-source models globally. The announcement stoked fears that America’s technological edge in AI could erode, threatening revenue for Western hyperscalers. At the same time, the US Central Command struck targets in Iran for a seventh consecutive night, pushing WTI crude oil up 3.7% to $81.88 a barrel and rattling already nervous markets.
Should investors sell immediately? Or is it worth buying VanEck Semiconductor UCITS ETF?
European chip stocks in the ETF’s portfolio felt the full force. ASMI and ASML surrendered 4.6% and 3.8% respectively, while STMicroelectronics tumbled 5% and Infineon slid 4.2%. Across the Atlantic, the Nasdaq Composite gave up 1.5%, and Japan’s Nikkei 225 slumped 4% as chip shares there dropped around 3%.
Investor behavior this week marked a break from previous chip routs. Rather than piling into the Magnificent Seven tech megacaps, capital rotated into defensive and value-oriented sectors such as financials, industrials, and energy. JPMorgan analysts, however, urged clients to treat the pullback as a buying opportunity, arguing the long-term growth narrative for the sector remains intact.
The numbers offer some perspective. Despite the carnage, the VanEck Semiconductor UCITS ETF is still up 72.99% year to date and 119.09% over the past twelve months. Its current price sits 5.27% below the 50-day moving average of €97.28—a break of the short-term trend but far from a death blow to the secular uptrend.
All eyes now turn to next week’s earnings from Alphabet, Tesla, and Intel. Alphabet, one of the biggest buyers of AI infrastructure, will test whether hyperscaler spending remains robust. How those reports land could determine whether this correction deepens or begins to stabilize.
