Leveraged ETFs Supercharge SK Hynix’s $26.5 Billion Nasdaq Coup as Seoul Sells Off

Korean chipmaker's ADRs debut strong on Nasdaq, but shares in Seoul drop 10% as leveraged ETFs amplify swings. Underlying HBM business boasts 72% margin.

SK Hynix has pulled off the biggest foreign IPO in US history, but the real story lies in the volatility machine it has ignited. The Korean chipmaker’s American Depositary Receipts debuted on the Nasdaq on July 10 and closed 13 percent above the issue price at $168.01 — a strong first day. Yet back home in Seoul, the common stock lost a tenth of its value in a single week, and a new breed of leveraged exchange-traded funds is amplifying the swings on both sides of the Pacific.

The company sold 177.9 million ADRs at $149 each, raising net proceeds of $26.5 billion and surpassing Alibaba’s $25 billion record for a foreign issuer in the US. Demand was seven times the supply, drawing global funds, technology specialists, sovereign wealth investors and Asia-focused money managers. The ADRs opened at $170, giving back a little ground by the close but still well above the offering price. SK Group Chairman Chey Tae-won called the listing a “historic moment” and told Bloomberg Television he was open to further US share sales, but only after a stable price performance is achieved. “That requires a better return first,” he said. “Once we have a better return, demand will rise. The most important thing now is to keep the stock price stable.”

The disconnect between New York and Seoul is striking. On Friday, the Korean-listed shares closed at 2,180,000 won, down 0.28 percent on the day and 10.10 percent lower than the previous week. The stock now sits 27.02 percent below its 52-week high of 2,987,000 won set on June 25. Strip out the weekly noise, however, and the longer-term picture remains dazzling: the shares have still gained 6.45 percent over the past 30 days and are up 222.01 percent year to date. The gap to the 52-week low of 491,500 won from October last year stands at 343.54 percent. Technically, the price is 1.76 percent above the 50-day moving average of 2,142,220 won, while the relative strength index of 46.1 sits squarely in neutral territory.

The volatility is partly engineered. According to a Nikkei analysis, the annualized 30-day volatility on SK Hynix has hit 114.70 percent — dwarfing the roughly 15 percent seen on the S&P 500. Korean retail investors poured 1.66 trillion won into leveraged single-stock ETFs tracking SK Hynix between July 1 and July 10 alone, Aju Press reported. The daily rebalancing of those products accounted for as much as 5.5 percent of the stock’s total trading volume. From July 13, the frenzy is set to go transatlantic: two new leveraged ETFs on the ADRs — one 2x long and one 2x short — begin trading in the US, promising to widen the price swings further.

Behind the headline-grabbing numbers, the underlying business is printing money. SK Hynix generated revenue of 52.5763 trillion won in its most recent quarter, with operating profit of 37.6103 trillion won — an operating margin of around 72 percent. The company commands an estimated 58 to 60 percent of the high-bandwidth memory (HBM) market, making it the indispensable supplier to Nvidia’s AI chips. At 4.8 times forward earnings, the stock trades at a steep discount to the industry median of 29.84 and even below Micron’s 6.6 multiple.

That discount may reflect a darkening outlook. Chief Executive Kwak Noh-jung has warned that the global memory industry is heading for the sharpest supply shortage in its history in 2027, with demand outstripping capacity well beyond 2030. Production of HBM chips for 2026 is already fully sold out, and fourth-generation HBM4 products now represent 40 percent of the company’s DRAM product mix. The memory sector is also nursing its own wounds: according to one report, memory stocks slid into a bear market on Tuesday, underscoring that even structural AI demand does not immunise the industry against violent reversals.

The $26.5 billion raised will fund a huge capacity expansion. The company plans to build a new chip-fab cluster in Yongin, a packaging facility in Cheongju, and purchase advanced EUV lithography equipment. The proceeds were due to be paid to the company on July 14. Separately, US Commerce Secretary Howard Lutnick has been pushing SK Hynix and Samsung to build additional fabrication plants in the United States. Chairman Chey confirmed that the company is evaluating a site in Indiana, while rival Micron has committed to a domestic investment programme exceeding $250 billion through 2035.

There is a macroeconomic dimension, too. South Korea’s finance ministry official Moon Ji-seong noted that the conversion of the dollar proceeds into won will help stabilise the domestic currency, which had recently hovered near 17-year lows. For SK Hynix, the dual listing has created a rare dynamic: a record-breaking capital markets success in one country coexisting with a choppy, ETF-jolted correction in its home market — and no one is sure which force will dominate next.
