SK Hynix’s Record-Breaking Nasdaq Debut Masks a Deeper Memory-Chip Rout

The iShares MSCI Global Semiconductors ETF gains 1.41% on SK Hynix listing hype, but established memory stocks like Western Digital and Seagate plunge on oversupply fears, highlighting a sharply divided market.

The iShares MSCI Global Semiconductors ETF swung back into positive territory on Thursday, gaining 1.41 percent to €18.83, as attention shifted to the imminent Nasdaq listing of South Korea’s SK Hynix. But beneath the relief rally lies a market sharply divided between exuberance for new listings and a punishing selloff in established memory-chip names.

Investor demand for SK Hynix’s American depositary receipts has been staggering. The order book was seven times oversubscribed, attracting institutional heavyweights such as Baillie Gifford and Coatue, and total orders topped $171.5 billion. The listing, expected to raise around $28 billion for the construction of two new fabrication plants, is set to trigger a wave of passive inflows to the sector, with analysts estimating up to $15 billion in fresh capital. Korean-listed SK Hynix shares surged more than 8 percent on Thursday, and foreign investors turned net buyers after weeks of selling.

Yet that optimism sits awkwardly alongside a brutal reckoning for other memory-chip stocks. Western Digital at one point plunged 28 percent, while Seagate lost 24 percent, both falling into technical bear market territory. The selloff ignored strong underlying fundamentals — Micron posted record third-quarter revenue of nearly $41.5 billion, a massive year-on-year jump — but reflected mounting fears of oversupply. Samsung’s own rapid profit growth only deepened those concerns, and the market began pricing in an inventory glut.

The whipsaw sentiment has also hit Nvidia, the sector’s biggest star. Since May, the company has shed roughly $1 trillion in market capitalization, and its forward price-to-earnings ratio has fallen to 18, the lowest since 2019 and cheaper than the broader S&P 500. While Nvidia did secure over 21 percent of the data-center networking market in the first quarter — a segment that grew nearly 40 percent year over year — the valuation reset suggests investors are bracing for slower growth ahead.

Broader forces are amplifying the volatility. Goldman Sachs has warned that the era of extreme earnings surprises in artificial intelligence may be ending, and high-profile investors such as Michael Burry have extended their short bets on the semiconductor sector into 2027. Hedge funds have been net sellers of U.S. technology stocks for four consecutive weeks. Meanwhile, the mega-cap tech companies continue to spend heavily: Microsoft, Amazon, and others are expected to pour $725 billion into AI infrastructure by the end of 2026. Meta is even considering renting out idle computing capacity to generate revenue.

Despite the turbulence, the ETF still shows a gain of more than 90 percent since January, though it sits about 12 percent below its June record high. Its 30-day volatility is an extreme 70 percent. On the technical side, the relative strength index stands at a neutral 49, and the fund is holding above its 50-day moving average of €18.20. Both JPMorgan and UBS have described the recent correction as merely unwinding earlier excesses — a view that will be tested when SK Hynix begins trading on Wall Street on Friday.

For now, the semiconductor market is caught between a blockbuster debut and a deep-rooted rotation out of memory plays. The direction the ETF takes next may depend on whether the listing’s euphoria can outweigh the growing inventory anxieties.
