SK Hynix Rides Alphabet’s CapEx Bombshell to a 4.86% Surge, but the Real Story Is a $4.83 Billion Packaging Bet
Published on 07/23/2026 at 18:44 | Redaktion boerse-global.de
The stars aligned for SK Hynix on Thursday, and the result was a rally that snapped weeks of punishing losses. Shares in the South Korean memory-chip giant closed at 1,919,000 won in Seoul, climbing 4.86% in a single session. The trigger came from across the Pacific: Alphabet, Google’s parent company, raised its 2026 capital expenditure forecast to between $195 billion and $205 billion, up from a prior range of $180 billion to $190 billion. For a company whose fortunes are tied to the insatiable appetite of hyperscale data centers, that upward revision was rocket fuel.
The broader KOSPI index jumped 4.40% to 7,096.89 points, reclaiming the 7,000 threshold for the first time in six trading sessions. Foreign investors piled into Korean equities to the tune of 2.15 trillion won net — the largest daily inflow since early May. Samsung Electronics, which supplies roughly half of Google’s server memory, rose 3.65% in sympathy.
Yet the headline-grabbing move in Alphabet’s cloud spending was only half the story. Hours before the market opened, SK Hynix’s board approved a 7.0931 trillion won ($4.83 billion) investment in its P&T7 advanced-packaging facility in Cheongju. The sum, equivalent to about 5.9% of the company’s equity, is earmarked for accelerating the opening of new clean rooms and expanding capacity for High-Bandwidth Memory (HBM) chips — the specialized memory modules that are the backbone of Nvidia’s AI accelerators and their rivals.
The timing was deliberate. SK Hynix commands a 56.4% share of the global HBM market, according to its own data, and the new investment is a direct acknowledgment that existing capacity is insufficient to meet demand. CEO Kwak Noh-jung has warned that supply constraints for AI memory chips could persist through 2027, a message that resonated with investors who have watched the stock shed 35.75% from its 52-week high reached in June.
Should investors sell immediately? Or is it worth buying SK Hynix?
A Nasdaq Debut That Tightens the Screws
A technical quirk is adding further support to the Seoul-listed shares. Since SK Hynix raised $26.5 billion through its American Depositary Receipts listing on the Nasdaq on July 10, the conversion limit of 2.5% has been reached. That means Korean common shares can no longer be swapped into the U.S.-traded ADRs, effectively capping the supply available to international investors. The ADRs themselves rose 6.6% in pre-market trading and settled at $170.40 in regular trade, giving the company a market capitalization of $1.21 trillion. Analysts have a consensus price target of $330 on the U.S. listing.
The supply constraint is a double-edged sword. It supports the Seoul stock price in the near term, but it also underscores how quickly the company’s valuation has been whipsawed by sentiment shifts. The stock is still up 195.37% year-to-date, yet it has fallen 24.89% over the past 30 days — a volatility that has left retail investors nursing losses while institutions and foreign funds buy the dip.
Earnings on the Horizon: The Real Test
All eyes now turn to July 29, when SK Hynix reports second-quarter results. The consensus is for operating profit between 60 trillion and 65 trillion won, with Bernstein estimating HBM revenue alone at $7.6 billion, a 25% sequential increase. The company’s first-quarter revenue came in at 52.6 trillion won, up 198% year-over-year, with a gross margin of 79.3%.
The product pipeline is accelerating. Sampling of the next-generation HBM4E chip began on June 17, with mass production slated for the third quarter of 2026. The P&T7 investment is designed to ensure that the packaging capacity is ready when those chips reach volume output.

Yet the macro backdrop remains fragile. The Philadelphia Semiconductor Index (SOX) has corrected 20% since the start of July, and JPMorgan strategist Jason Hunter has warned that the coming weeks will determine whether the AI trade follows the pattern of the late-1990s divergence between technology stocks and chipmakers. SK Hynix also had to deny reports that it was considering acquiring Intel’s Ohio fabrication plant, a rumor that briefly added to the noise.
For now, the combination of Alphabet’s spending commitment and SK Hynix’s own capital deployment has given the stock a reprieve. But with the stock still 35.75% below its peak and an earnings report that will test whether the HBM supercycle is as durable as the company’s CEO insists, the next few trading sessions will be decisive.
