SK Hynix’s $31 Billion Bet: Can Record Spending Outrun a 50% Stock Rout?
Published on 07/29/2026 at 14:42 | Redaktion boerse-global.de
SK Hynix is caught in a paradox that has confounded even seasoned Korea watchers. The memory-chip giant just posted a sixfold jump in quarterly profit, yet its shares have been sliced nearly in half from a record high touched only last month. The disconnect between booming fundamentals and a brutal selloff has become so acute that South Korean regulators stepped in for an emergency meeting Wednesday.
The stock closed at 1,401,000 won on Wednesday, down 9.61% on the day. That followed a 14.65% plunge on Tuesday — one of the worst single-day routs in the company’s history. Over the past 30 days, SK Hynix has shed roughly half its market value, with the share price now sitting almost 36% below its 50-day moving average. The carnage wiped out around 190 trillion won in market capitalization in the days leading up to the quarterly report.
What Triggered the Panic
The catalyst for Tuesday’s meltdown was not a weak outlook from SK Hynix itself. Instead, investors were spooked by the spectacular debut of ChangXin Memory Technologies (CXMT) in China, combined with reports that a state-linked Chinese firm has begun producing immersion lithography systems for chip manufacturing. The fear: a post-IPO capacity surge and accelerated technological catch-up by Chinese rivals.
Analysts at Mirae Asset Securities argue the concern is less about CXMT’s current profitability and more about what its stock market success means for future investment. China’s growing ambitions in memory chips — particularly in standard DRAM and NAND — add another layer of uncertainty, even if CXMT still lags significantly in the high-bandwidth memory (HBM) segment that drives SK Hynix’s profits.
Should investors sell immediately? Or is it worth buying SK Hynix?
The selloff cascaded across the sector. The KOSPI index tumbled 10.84%, its worst session in roughly five months. Samsung Electronics lost more than 13%, while Micron Technology shares fell 8.95% in New York. SK Hynix’s American Depositary Receipts, listed on the Nasdaq just this month, slid below the psychologically important $130 mark, closing at $130.49 — a new record low since the listing.
Record Earnings, but Not Enough
When SK Hynix finally delivered its numbers, the reaction was telling. The company reported a sixfold increase in quarterly net profit, comfortably beating analyst estimates. Yet the stock kept sliding. The problem, according to market participants, is that expectations had become so elevated that even a blowout quarter failed to satisfy.
Management pushed back hard against the pessimism. Executives dismissed concerns that the AI-driven demand cycle is peaking, insisting there is no end in sight for the explosive appetite for HBM chips used in AI accelerators. To underscore their conviction, they announced a record capital expenditure plan of $31 billion for this year.
The company is already looking years ahead. SK Hynix is in active negotiations with major tech firms to secure supply contracts for HBM chips as far out as 2027. The goal is to lock in demand before competitors can catch up. In the second half of this year, the company will begin mass shipments of HBM4, the next-generation memory standard, with pricing negotiated individually for each customer based on development costs, DRAM prices, and opportunity costs.
Leveraged Products Amplify the Pain
Regulators and market participants increasingly point to structural factors that have magnified the selloff beyond what fundamentals alone would justify. South Korea introduced leveraged single-stock products in May, and these instruments are believed to have exacerbated the volatility. The government’s emergency meeting on Wednesday — triggered by the KOSPI’s roughly 40% decline from its June peak — focused partly on whether to restrict such products if the turbulence persists.
Owen Lamont of Acadian Asset Management describes the situation as one of “incredible uncertainty” about how AI technology will ultimately reshape the economy. While he stops short of blaming leveraged products entirely for SK Hynix’s volatility, he notes they can amplify market swings.
Wall Street Split on What Comes Next
The analyst community is sharply divided. Morgan Stanley, Mirae Asset Securities, and KB Securities all characterize the selloff as a buying opportunity rather than an exit signal, pointing to price-to-earnings ratios of just two to five for a company on track for record profits.
SK Hynix at a turning point? This analysis reveals what investors need to know now.
David Riedel of the Riedel Research Group takes a more measured view, calling the decline a necessary correction after an overheated rally. The stock’s recent trajectory had been “really too much,” he said, and the shares “deserved to let off some steam.”
Technical indicators offer mixed signals. The relative strength index has fallen to 33.2, deep in oversold territory and suggesting a potential short-term bounce. The stock remains 27% above its 200-day moving average, however, indicating the longer-term trend is still intact despite the recent carnage. Year-to-date, SK Hynix is still up 128.88% — a reminder of just how extreme both the rally and the correction have been.
What Investors Are Watching Now
All eyes turn to Samsung Electronics, which releases detailed second-quarter results on Thursday. The market will be looking for clues on whether the selloff is a sector-wide phenomenon or specific to SK Hynix. Analysts expect memory chip prices to rise at least 25% in the third quarter, driven by persistent HBM shortages that could last into 2028.
For SK Hynix, the immediate question is whether the government’s crisis meeting can calm markets or whether leveraged products will continue to roil the KOSPI. The company’s earnings call and any commentary on those 2027 HBM pricing negotiations will likely determine whether the selling abates or intensifies in the sessions ahead.
