US listing raised $26.5 billion, setting a record for foreign companies; HBM market share nearing sixty percent leads the global; DRAM and NAND prices reach new historical highs, Samsung's long-term contract pricing model reshapes the cycle logic. This article deeply analyzes valuation discounts, revaluation, concerns about advanced product shipmen
In the first week of August, SK Hynix, the leader in Asian memory chips, experienced a thrilling roller coaster ride in its American Depositary Receipts (ADR). On August 4th local time, following the first coverage by at least six Wall Street investment banks with a "Buy" rating, SK Hynix ADR surged by 8.17% to close at $154.38, driving a collective surge in the US memory sector, with Flash Technology rising over 10%, Micron Technology up more than 7%, and the Fortune Semiconductor Index soaring 6.6%. However, just two trading days later, due to the dual impact of earnings realization pressure and Middle East geopolitical hedging sentiment, the sector sharply reversed, and SK Hynix ADR dropped nearly 5%, while Western Data plummeted by 13% in a single day. Between gains and losses, the market's divergence around the "AI memory super cycle" reached a peak.
## Listing in the US: Raising $26.5 Billion Rewrites History
The starting point of this trend can be traced back to SK Hynix's listing on Nasdaq on July 10th. This South Korean memory giant issued approximately 178 million ADRs at a price of $149 per share, raising a total of $26.5 billion, surpassing the record set by Alibaba in 2014. It became the largest IPO for a foreign company listing in the US, second only to SpaceX's $85.7 billion fundraising. On its first day of listing, SKHY opened up with a gain of 14%, briefly touching $177, and its market capitalization reached $1.24 trillion, clearly demonstrating the global capital's pursuit of the AI High Bandwidth Memory (HBM) race.
The significance of listing in the US is not just about financing. For SK Hynix, whose main trading market is Seoul, the ADR provides access to the world's most active pool of technology investment funds, enabling it to reach a wider range of institutional investors and laying the groundwork for reshaping valuation systems later on. However, it is noteworthy that, due to the overall pullback in the semiconductor sector since July, SK Hynix ADR stock price has retreated by about 20% from its historical high set on July 14th—providing an entry narrative window for investment banks.
## Six Investment Banks Unanimously Bullish: From "King of Memory" to "AI Computing Weapon Merchant"
From August 3rd to 4th, at least six investment banks, including Bank of America Global Research, Rosenblatt Securities, Stifel, Wolfe Research, RBC Capital Markets, and William Blair, issued a rating equivalent to "Buy" when covering SK Hynix for the first time. Rosenblatt gave the highest price target across the board at $320, implying over one time period of upside from the current price. Stifel, Wolfe, and RBC set price targets in the range of $200 to $240, while Bank of America simultaneously set an ADR price target of $250, explicitly stating that this South Korean chip manufacturer holds a dominant position in the HBM field, which will drive it into an "earnings super cycle that Wall Street has not yet fully reflected."
The logic for the collective bullish view from the investment banks is highly consistent and can be summarized in three points:
* Market Share Moat: According to Counterpoint Research data, SK Hynix holds about 58% of the global HBM market share in Q1 2026, and its position in the memory supply segment for AI training chips is virtually irreplaceable; its priority position in the HBM3E/HBM4 supply landscape for NVIDIA's next generation accelerator cards is clear. Capital Expenditure Wave: Bankers estimate that Amazon, Microsoft, Alphabet, and the top five cloud vendors will have a combined capital expenditure of $730 billion in 2026, nearly doubling year-over-year, with potential to exceed $1 trillion by 2027 to 2028. The arms race for AI infrastructure directly translates into visibility of storage orders.
Product Pricing Power: RBC estimates that as customers transition to HBM4, HBM product pricing still has over 50% upside potential, and the exclusivity of leading-edge process capacity will further strengthen suppliers' bargaining power.
Is Valuation Discounting an "Opportunity" or a "Trap"?
It is worth noting that most investment banks use "valuation discount" as a core argument for buying. Since the listing of SK Hynix ADR, its valuation has been lower than its American peers like Micron. RBC estimates that the stock currently has a discount of about 20% to 25% compared to US memory industry peers. Analyst William Blair points out that the listing in the US provides SK Hynix with an opportunity to close the valuation gap with Micron. As the company becomes deeply tied to the AI and data center end markets and long-term earnings visibility improves, the stock price will experience a more structured revaluation. However, some institutions remind that the discount itself reflects the market's pricing of Korean corporate governance discounts, fluctuations in the Korean won exchange rate, and supply chain geographical risks, and it may not disappear automatically due to the listing. There is still a cross-market arbitrage mechanism between SK Hynix ADR and its Seoul common stock, and changes in liquidity structure require time to verify.
"Flaws in Earnings": Shipment Delays Trigger AI Spending Concerns
Before investment banks could provide comprehensive coverage, SK Hynix released its first earnings report after the US listing: quarterly profit reached a new high, but due to delays in shipments of some advanced storage products, performance did not meet analyst expectations, which once triggered concerns about a slowdown in AI spending pace. This "flaw" becomes a foreshadowing sign for a subsequent stock price pullback—in a market with high expectations, any data below "perfect" will be magnified. The sharp drop on August 6th was the concentrated release of this sentiment. On that day, geopolitical risks in the Middle East pushed oil prices higher, US Treasury yields simultaneously rose, suppressing high-valuation growth stocks, and combined with earnings realization pressure, the US storage sector collectively plummeted: Western Data fell 13%, Flash fell 6.81%, Quaker and Jefferies both lowered their price targets, SK Hynix ADR fell nearly 5%, Micron Technology fell over 1%. Analysts point out that Western Data's gains exceeded 160% year-to-date, and market expectations are at historic highs; only earnings and guidance that "far exceed expectations" can support continued price appreciation—this precisely exposes a weakness of super cycle trading: expectations run faster than fundamentals.
Industry Outlook Has Not Been Falsified: DRAM, NAND Prices Set New Records Compared to short-term price fluctuations, the fundamentals remain strong. According to DRAMeXchange data, the spot price for 16Gb DDR5 has reached $51, up 733% year-over-year; 16Gb DDR4 reached $85.2, up 896%; The average price for 64GB DDR5 server modules has surpassed $1480, and 64GB DDR4 reached $1300, both setting new historical highs. In the NAND sector, the average contract price for 128Gb MLC chips in July was $30.1, up 4.3% month-over-month, achieving a continuous increase for 19 months. China Institute Consulting data shows that the average DRAM contract price for Q2 2026 grew by 58% to 63% month-over-month, and NAND Flash contract prices grew by 70% to 75% month-over-month, with the spot price for DRAM in July jumping 14% month-over-month again.
The more critical structural change is the shift in contract models. According to the research report released by Goldman Sachs on August 1, Samsung Electronics has incorporated 60% to 70% of its storage sales into Long-Term Agreement (LTA) systems, with terms clearly favoring the supply side: the maximum quarterly price drop limit is set at 5%, while price increases are unrestricted, accompanied by five-year rolling contracts and multi-year prepayment mechanisms. The scope has expanded from traditional DRAM to HBM and enterprise SSDs. SK Hynix is also following a similar long-term contract strategy. Analysts believe this signals that the storage indu stry is saying goodbye to the "boom-bust" cycle of the past few decades—when demand weakens, long-term contracts can support prices; When supply is tight, suppliers can still benefit from rising prices, significantly increasing the certainty of profitability.
## Can the Super Cycle Continue?Where is the Divergence?Bull arguments suggest that AI server memory consumption far exceeds that of traditional servers, and the demand for HBM, enterprise SSDs, and high-density DDR5 is visible until 2028. Leading firms predict that the proportion of HBM in Samsung and SK Hynix DRAM revenue will increase from 8% and 14% in 2026 to 16% and 22% in 2027, further reaching 18% and 25% by 2028;SK Hynix's HBM4 has passed NVIDIA certification, with order visibility extending to 2027, providing a clear path for profit growth. Morgan Stanley even stated that supply and demand shortages in the storage market will not be resolved before 2028.
Cautious voices point to three risks: First, AI capital expenditure is highly concentrated among a few cloud vendors; If the pace of compute deployment slows down, storage demand will quickly reverse, and the "shipment delay" observed previously might be a signal. Second, as manufacturers like China Changxin Storage (CXMT) accelerate capacity expansion, the market capitalization of their KOSDAQ listing, once approaching the scale of $500 billion, and the yield rate of DDR5 may compress price increase space in the medium to long term. Third, TrendForce expects NAND supply to become looser in the second half of 2027, and the cycle top might arrive earlier than market expectations. Furthermore, rekindled inflation expectations triggered by rising oil prices could pressure the Federal Reserve to maintain a tight stance, thereby suppressing the overall valuation level of high-valuation technology stocks.
## Conclusion: A New Narrative of Revaluation Begins, Volatility Becomes the New Normal For investors holding Asian memory chips ADRs, the first week of August's market signals two things. On one hand, a consensus is forming on Wall Street regarding the "revaluation" of SK Hynix, and the shift in global investor structure brought by the $26.5 billion in fundraising will continue to enhance the pricing power of Asian memory leaders in the US stock market. On the other hand, the super cycle trading has entered a "high volatility" phase; any earnings blemishes, geopolitical disturbances, or changes in interest rate expectations could trigger sharp pullbacks, with daily swings of 5% to 8% becoming the norm. Before HBM4 ramp-up and cloud vendor capital expenditures materialize, neither bulls nor bears can fully convince the other. What is certain is that memory chips have transformed from "cyclical goods" into "strategic resources for the AI era," and US ADRs are becoming the most direct and transparent channel for global capital participation in this narrative. For investors, rather than dwelling on short-term volatility, it is better to focus on three core variables: HBM4 production progress, cloud vendor capital expenditure guidance, and the monthly trend of DRAM/NAND contract prices—these will determine the ultimate outcome of this super cycle revaluation battle.
