SK Hynix shares came under heavy pressure after Korean brokerage KIS projected second-quarter earnings below market expectations, even as the memory chipmaker was still expected to post sharp growth from the previous quarter and the same period last year.
The selling highlighted a key tension now facing one of the world’s most important suppliers of high-bandwidth memory, or HBM: long-term supply contracts are helping stabilize earnings, but they are also limiting how much the company can benefit from sudden price jumps in the broader memory market.
KIS estimated SK Hynix’s second-quarter revenue at 80.9 trillion won, up 54% from the previous quarter and 264% from a year earlier. Operating profit was forecast at 60.4 trillion won, representing a 61% quarter-on-quarter increase and a 556% year-on-year gain. Despite those strong numbers, the operating profit estimate was about 8% below the market expectation of 65 trillion won.
That gap was enough to trigger a sharp sell-off. SK Hynix shares fell more than 10% during trading, dropping below 2 million won. The decline left the stock about 33% below its record high reached on June 25, placing one of Asia’s most closely watched artificial intelligence hardware plays firmly into correction territory.
The weakness did not stop in South Korea. Leveraged storage-related ETFs in Hong Kong and mainland China dropped more than 22%, while several A-share memory chip companies fell more than 7%. The reaction showed how quickly concerns over one major supplier can spread across chip-linked trades, especially after a long rally built on expectations for AI-related demand.
Why the forecast disappointed
The main issue was not a collapse in demand or a sudden deterioration in SK Hynix’s business. According to KIS, the lower forecast reflected a recalculation of assumptions tied to long-term agreements, known as LTAs.
SK Hynix has heavy exposure to HBM, a premium memory product used in advanced AI accelerators and high-performance computing systems. HBM is one of the most profitable parts of the memory industry, and SK Hynix has built a leading position in the category.
However, much of the company’s HBM supply is sold under fixed or pre-agreed pricing arrangements. These contracts typically cover longer periods and are designed to give both chipmakers and customers greater visibility over supply, pricing and production schedules.
That structure can be helpful during downturns because it reduces exposure to sudden price drops. But it can also cap gains during periods when market prices rise quickly.
KIS said spot DRAM prices rose by about 30% during the quarter, while NAND prices climbed roughly 50%. In contrast, HBM pricing did not adjust as quickly because of contract terms. As a result, average selling price growth for SK Hynix was more limited than some traders had expected.
The market had been looking for a stronger earnings surprise from the company, especially after months of enthusiasm around AI-related chip demand. Instead, the KIS forecast suggested that the company’s HBM strength may not translate immediately into the same level of near-term profit upside seen in spot memory products.
Fixed-price contracts cut both ways
The heavy use of fixed-price arrangements has become one of the defining features of the HBM market. These agreements help customers secure supply in an industry where capacity is tight and qualification processes are complex. They also help manufacturers plan capital spending and production more efficiently.
For SK Hynix, that stability is valuable. HBM production requires advanced packaging, specialized manufacturing processes and close coordination with major chip designers. Long-term agreements can reduce uncertainty around output, inventory and revenue.
But the latest market reaction shows the downside. When spot prices for DRAM and NAND rise sharply, traders may expect all memory producers to benefit immediately. HBM contracts can delay that benefit, especially when prices have already been set for a meaningful portion of future shipments.
That difference between spot market exposure and contract-based revenue appears to have driven much of the disappointment in the KIS report. The brokerage said its revision was linked to updated LTA assumptions rather than a weakening of SK Hynix’s competitive position.
In other words, the issue was timing and pricing structure, not necessarily demand.
Profit forecasts revised lower
KIS also lowered its profit forecasts for SK Hynix for 2026 and 2027. The brokerage cut its 2026 profit estimate by 9% and its 2027 estimate by 11%.
Even with those reductions, KIS maintained a target price of 3.8 million won for the stock. It also projected that SK Hynix could achieve an operating margin of 74.6% in the second quarter of 2026, underscoring that the brokerage still sees the company as a highly profitable long-term beneficiary of the HBM cycle.
That combination of a lower near-term forecast and an unchanged target price reflects the broader debate now surrounding the stock. Short-term traders are focused on whether earnings can keep beating aggressive expectations. Longer-horizon market participants are weighing whether contract-based HBM revenue will support more stable profit levels over several years.
The market reaction suggests that expectations had become stretched. After a powerful rally, even strong growth forecasts were not enough. Traders appeared to be positioned for an even larger earnings upgrade, and the absence of that upgrade triggered a rapid repricing.
Selling pressure spreads across chip trades
The decline in SK Hynix added to broader volatility across memory and semiconductor-related shares. Market data cited in the report showed memory chip stocks have fallen more than 20% over the past two weeks, a move commonly viewed as a technical correction.
Profit-taking also intensified after the company’s American Depositary Receipt activity in the United States, according to the report. Funds that had benefited from the earlier rally appeared to lock in gains, adding to pressure on storage and semiconductor-linked sectors.
The speed of the move reflected how crowded the AI hardware trade had become. SK Hynix has been viewed as one of the clearest winners from surging demand for advanced memory used in AI data centers. Any sign that earnings may fall short of the most optimistic forecasts can therefore have an outsized impact on related shares.
Mainland Chinese memory names were also hit, showing that the pressure was not limited to companies with direct HBM exposure. When traders reduce risk in a fast-moving sector, selling often spreads to suppliers, peers, ETFs and thematic products, regardless of whether each company faces the same earnings issue.
Leveraged ETFs amplified that move. These products are designed to multiply the daily performance of an underlying index or basket, which means they can fall sharply when sentiment turns. The more than 22% decline in some storage-related ETFs reflected both the severity of the sell-off and the additional volatility created by leverage.
A shift from spot prices to contract visibility
KIS said the storage industry is moving toward longer agreements, with some arrangements extending three to five years. If that trend continues, market attention may gradually shift away from short-term price spikes and toward long-term earnings stability.
That would mark an important change for memory chip trading. The sector has historically been highly cyclical, with profits swinging sharply based on supply, inventory levels and spot pricing. Booms are often followed by downturns as producers expand capacity and prices eventually fall.
Longer-term contracts may smooth some of those swings. They can improve revenue visibility and reduce the risk of sudden earnings collapses. In theory, that could support a higher valuation over time if traders become more confident in the durability of cash flow.
But the transition also creates new challenges. When more revenue is locked into contracts, the company may not fully capture short-term price increases. That can be frustrating during a boom, especially when share prices have already priced in rapid margin expansion.
For SK Hynix, the question is whether the market will reward stability or punish slower upside during strong pricing cycles. The latest sell-off suggests that, at least in the near term, traders were focused more on missed upside than on reduced downside risk.
HBM leadership remains central
SK Hynix’s strategic position in HBM remains the core reason many traders continue to follow the stock closely. The company is widely regarded as a leading supplier in high-speed memory for AI accelerators, and estimates cited in the market suggest it controls a major share of the global HBM segment.
That leadership matters because HBM is difficult to manufacture at scale. It requires stacking memory chips vertically and connecting them through advanced interconnect technologies. Production yields, packaging capacity and customer qualification all play major roles in determining how much supply can reach the market.
Demand remains closely tied to AI infrastructure spending. Large technology companies, cloud providers and chip designers require advanced memory to support increasingly complex AI models. As long as spending on AI servers remains strong, HBM suppliers are expected to remain in a favorable position.
KIS concluded that SK Hynix’s expansion in HBM capacity and broader contract coverage could support sustainable profitability. The brokerage’s view suggests that near-term price adjustments do not necessarily change the longer-term growth outlook.
Still, the market is now asking a more demanding question. It is no longer enough for SK Hynix to be a major AI beneficiary. Traders want to know how much of that demand will flow into earnings, how quickly pricing can adjust, and whether expectations have run too far ahead of actual contract economics.
Wider risk sentiment feels the impact
The sell-off also came at a time when technology shares and digital token markets have been moving closely together. Some market measures show the 30-day correlation between major virtual coins and the Nasdaq has climbed to around 0.9, indicating that high-growth technology shares and digital assets have recently been trading in a highly synchronized way.
That does not mean SK Hynix’s earnings directly determine cryptocurrency prices. The operational link is limited, especially because HBM demand is driven mainly by AI computing rather than token mining. But both areas can be sensitive to liquidity, risk appetite and expectations for technology-sector growth.
When semiconductor shares fall sharply, it can weaken sentiment across other speculative or high-volatility assets. Token traders often respond to the same macro signals that affect tech shares, including interest-rate expectations, U.S. equity market direction, liquidity conditions and appetite for growth-related trades.
The latest correction in memory stocks may therefore matter beyond the chip sector. It adds another source of volatility at a time when many risk assets are already reacting quickly to changes in sentiment.
Supply tightness supports the long-term case
Global supply chain reports continue to suggest that tightness in parts of the memory chip market could last through 2027. If that proves correct, suppliers with advanced production capacity and strong customer relationships may remain well positioned.
For SK Hynix, the key will be execution. Expanding HBM capacity is expensive and technically challenging. The company must balance customer demand, pricing discipline, yield improvement and capital spending. It also has to manage the risk that current shortages eventually lead to overexpansion across the industry.
The longer-term contract model may help reduce that risk. By securing commitments from major customers, memory producers can build capacity with greater confidence. Customers, in turn, gain better access to critical components in a constrained market.
The trade-off is now clear. Stability comes at the cost of immediate exposure to spot-market upside. That is the central issue behind the latest earnings debate.
Outlook remains intact but expectations reset
The KIS report did not present SK Hynix as a company facing structural weakness. On the contrary, the projected earnings growth remains substantial, and the company’s HBM position continues to support a favorable long-term outlook.
The market reaction was instead a reset of expectations. After a strong rally, traders had priced in a near-perfect earnings path. A forecast that was strong in absolute terms but below consensus was enough to trigger selling.
The next phase for SK Hynix will likely depend on how clearly the company can explain its contract structure, pricing outlook and capacity expansion plans. Traders will also watch whether HBM pricing begins to adjust more meaningfully in future quarters as existing agreements roll forward or are renewed.
For now, the message from the market is direct: AI demand remains powerful, but valuation discipline has returned. SK Hynix is still viewed as a central player in the advanced memory cycle, yet its share price must now absorb the reality that long-term contracts can smooth earnings on the way down while limiting windfall gains on the way up.
