VanEck Semiconductor ETF Braces for ASML and TSMC Earnings After Korean Leverage Shock and Nvidia Curbs

VanEck Semiconductor ETF recovers to €98.67 after Korean leveraged ETF meltdown and Nvidia export restrictions; ASML and TSMC earnings to test AI trade resilience.

The VanEck Semiconductor UCITS ETF clawed back to €98.67 on July 14, a 1.07% recovery from Monday’s sell-off, as the fund navigates the fallout from a historic crash in Korean leveraged products, new export restrictions on Nvidia, and two pivotal earnings releases that will test the resilience of the AI trade. The ETF still sits 12.19% below its June 30 all-time high of €111.18, yet its 12-month return of 137.05% underscores the sector’s explosive longer-term trajectory.

Monday’s bloodletting in Seoul sent shockwaves through global chip markets. The KOSPI plunged 8.95% to 6,806.93 points, its first close below the 7,000 mark since May 4, triggering the year’s seventh circuit breaker. Samsung Electronics tumbled 10.70%, while SK Hynix recorded its worst single-day drop ever at 15.37%. The culprit: a US$50 billion pile of 2x leveraged single-stock ETFs on Korean memory leaders, whose forced rebalancing amplified the losses. According to Barclays, 93% of these products are held by retail investors—far above the 75% level in the US. Korea Investment & Securities analyst Yeom Dong-chan cautioned that the leveraged ETFs were accelerants, not the root cause, noting that morning swings were more violent than the afternoon rebalancing. The damage, however, was real: Korean semiconductor stocks have shed roughly 1,522 trillion won in market capitalization since June 25, and the KOSPI’s price-to-earnings multiple has contracted to 6.36, a level not seen since the 2008 financial crisis.

The turmoil cascaded across the Atlantic. SK Hynix’s ADR fell 9.32%, SanDisk lost 12.63%, Micron dropped 4.32%, and AMD gave up 4.21%, dragging the Nasdaq down 1.55%. The VanEck ETF closed Monday at €97.63. Adding to the pressure, Nvidia unveiled tighter controls on high-end AI chip sales in Asia, slashing its list of authorized buyers in Singapore, Malaysia, and Japan by more than half and introducing a new “white list.” The stock shed 3.4% on the news. Nvidia remains the fund’s largest holding at roughly 17.75%, so any prolonged regulatory headwind directly impacts performance. The volatility index for the semiconductor sector (VXSMH) spiked to 64, while the realized volatility hit 62.4, and the ETF’s own 30-day annualized volatility stands at 63.82%—a stark reminder of the market’s frayed nerves amid US margin debt climbing to a record US$1.416 trillion.

All eyes now turn to ASML’s second-quarter report on July 15, followed by TSMC’s numbers later in the week. Analysts expect ASML to post net profit of €2.61 billion on revenue of €8.8 billion, but the forward guidance—currently pegged at €36–€40 billion for 2026—will be the true barometer of AI infrastructure demand. The Dutch lithography giant is the sole supplier of EUV machines, and its China exposure has already dropped from 36% of system sales at the end of 2025 to just 19% early this year, a direct consequence of tightening US export controls. Any further downgrade to the China outlook could ripple through the entire supply chain.

Beneath the short-term noise, the underlying fundamentals remain robust. Micron posted Q3 fiscal 2026 revenue of US$41.46 billion, up 345.7% year-over-year with a gross margin of 84.9%. Nvidia’s Q1 fiscal 2027 revenue reached US$81.62 billion, driven by US$75.25 billion from data center chips. Broadcom pushed its AI semiconductor revenue 143% higher to US$10.8 billion, though its stock slipped below US$400 on Monday amid reports of insider selling. Investor Gavin Baker has flagged a “mega-bull case” for Nvidia, Micron, Broadcom, and Applied Materials if open-source AI models shift margins from large labs to infrastructure providers. The VanEck ETF, which also holds TSMC, Applied Materials, AMD, KLA, Lam Research, Intel, and ASML among its top positions, has gained 79.53% year-to-date. With ASML and TSMC set to report within days, the market will soon discover whether the AI order book remains insulated from geopolitical friction—or whether the recent volatility is a preview of deeper headwinds.
