Investors have flocked to artificial intelligence (AI) stocks in recent years to bet on the next game-changing technology -- and some of the first winners have been companies providing products and services essential to the functioning of AI. U.S. investors have had access to many of these players, from AI chip leader Nvidia to memory giant Micron Technology, as they trade in the U.S. on the Nasdaq.
And now, since July 10, U.S. investors also have easy access to SK Hynix, a South Korean company that's playing a major role in the AI revolution. This key Nvidia partner has been delivering triple-digit growth, and it just launched American depositary receipts (ADRs) on the Nasdaq. The shares advanced 13% during their first day of trading and closed at just over $168. Is SK Hynix a buy? Let's find out.

SK Hynix is South Korea's second-biggest company after Samsung, and it's seen earnings soar amid the AI boom. The company makes a variety of memory types that serve many devices you probably use daily -- such as smartphones and computers -- and are used across industries too. But where SK Hynix has truly stood out in recent times is in the area of high-bandwidth memory (HBM), which involves a stacking of memory close to a processor. HBM is in high demand from AI customers, and this has supercharged SK Hynix's growth.
In the recent quarter, for example, the company reported revenue growth of 198% to about $35 billion dollars, a record level. Net income soared 398%, and operating margin came in at 72%.
Of course, SK Hynix isn't alone in this market, as it faces competition from other memory providers such as Micron and Sandisk, and business has been booming for all of these players. But SK Hynix has secured leadership in the key market of HBM, and this is significant considering the need for this type of memory in AI. SK Hynix held 58% share globally of the HBM market as of the end of the first quarter, according to Counterpoint Research.
Another significant point is that SK Hynix is Nvidia's main memory partner, and considering Nvidia's dominance in the AI chip market, this is a big reason to be optimistic about SK Hynix's prospects. The two companies even reinforced their relationship recently, signing a multi-year technology partnership. It involves SK Hynix supplying memory across a broad range of areas, from AI infrastructure to personal AI and robotics.
"SK Hynix has been Nvidia's largest memory partner and will continue to be our largest memory partner," Nvidia chief Jensen Huang said at the time.
Finally, SK Hynix trades at a discount compared to the industry and rival Micron. Prior to the ADR debut, SK Hynix traded at 4.8x 12-month forward earnings estimates, according to a CNBC report citing LSEG data. The industry median is 29.84x, and Micron's is 6.6x, the data showed.
Now, let's return to our question: Should you buy SK Hynix ADRs? Demand in the memory market is soaring thanks to the AI boom -- in fact, demand is so high that these companies don't have to worry much about rivals. There is enough need for memory to support enormous growth among leading memory players.
And the points I mentioned above make SK Hynix a compelling choice. But it's important to keep in mind that the memory market is known for being cyclical, with periods of intense demand followed by declines. The major question is whether this AI boom will be different, for example, leading to a much longer phase of growth than in past cycles, or less of a drop in demand in the later stages of the cycle.
This uncertainty means you should let your risk tolerance guide you. If you're a cautious investor and you're worried about the cyclical nature of this market, you may want to watch SK Hynix from the sidelines. But if you're a growth investor interested in diversifying across AI players, you might consider scooping up a few shares of SK Hynix at today's levels, as they may have room to run, particularly over time.

Four leading AI models discuss this article
"The valuation disparity between SK Hynix and its US peers is unsustainable and will likely narrow as global institutional capital flows into the ADRs."
SK Hynix’s ADR debut is a tactical play to capture retail liquidity, but the valuation spread is the real story. Trading at ~4.8x forward earnings against a 29.8x industry median suggests a massive 'Korea Discount' that the market is finally repricing. While the 58% HBM market share is a moat, the real risk isn't just cyclicality—it's the capital expenditure arms race. Samsung is aggressively ramping HBM3E production to reclaim share, and Micron is moving up the stack. If HBM supply catches up to demand by 2025, the current 72% operating margins will face immediate compression. I'm bullish on the valuation gap, but wary of the looming supply glut.
The 'Korea Discount' exists for a reason: complex corporate governance, geopolitical sensitivity regarding China, and the inherent volatility of a commoditized memory cycle that rarely sustains these margins.
"N/A"

"SK Hynix's valuation discount reflects rational skepticism of memory-cycle history, not a hidden gem—the 72% margin and 198% revenue growth are peak-cycle signals, not proof of durability."
SK Hynix's 4.8x forward P/E versus 29.8x industry median looks cheap until you ask why. The article conflates a cyclical peak with structural demand—memory cycles have killed investors before. Yes, 58% HBM share and Nvidia partnership are real moats, but the 72% operating margin is unsustainable; margins compress viciously when supply catches up. The July ADR debut at $168 saw 13% pop—classic liquidity-driven euphoria, not fundamental repricing. Geopolitical risk (South Korea, U.S.-China tensions) and Samsung's HBM ramp are underplayed. The article's 'enough demand for all players' claim ignores that memory is a commodity—price wars erase margins fast.
If AI infrastructure capex truly is structurally higher for the next 5+ years (not just cyclical), SK Hynix's partnership lock with Nvidia and 58% HBM dominance could justify premium multiples, and the current valuation gap versus Micron suggests significant upside if the cycle doesn't crack.
"The strongest risk is that AI memory demand proves cyclical rather than durable, leading to margin compression and multiple de-rating despite current enthusiasm."
The article touts SK Hynix as an AI memory winner, highlighting 198% revenue growth to ~$35B, 398% net income rise, and a 72% operating margin, plus 58% HBM market share and a Nvidia tie-up. However, the thesis hinges on a cyclical and potentially transient AI memory boom. Key risks: HBM demand could cool as AI capex cycles mature, price/volume pressure could erode margins, and Nvidia-led demand may not be as sticky across years as implied. The ADR listing adds currency and regulatory risk. If the AI hardware cycle weakens or rivals snag more memory share, the stock could re-rate downward despite the current sentiment.
Even if the cycle softens, SK Hynix could still benefit from a diversified AI memory demand base and ongoing HBM upgrades; the stock's cheap multiple may reflect genuine downside risk, not just timing.
"HBM's transition from commodity to bespoke infrastructure justifies a valuation re-rating beyond cyclical expectations."
Gemini and Claude are obsessed with the 'Korea Discount' and cyclicality, but they miss the real structural shift: HBM is no longer a commodity. Unlike standard DRAM, HBM3E is a bespoke, high-margin engineering product sold under long-term supply agreements. This isn't a typical memory cycle; it’s a foundry-like model. If SK Hynix maintains its technical lead, the 4.8x P/E isn't a value trap—it’s a massive mispricing of a company effectively functioning as a critical AI infrastructure utility.

"Specialized products aren't immune to commoditization—and Nvidia's bargaining power in a two-supplier market is underestimated."
Gemini's 'foundry-like model' claim needs stress-testing. Long-term supply agreements sound durable until a customer (Nvidia) demands price cuts mid-contract or pivots to in-house memory. HBM3E is specialized, yes—but so was 3D NAND before Samsung commoditized it. The real question: does SK Hynix's technical lead survive a determined competitor with deeper pockets? Samsung's HBM ramp isn't hypothetical; it's happening now. Calling this a 'utility' ignores that utilities have regulated returns. Memory doesn't.
"HBM3E isn't a durable moat; even with long-term deals, price/volume concessions and aggressive ramping by Samsung could compress margins, undermining the 4.8x P/E thesis."
Gemini's euro-claim that HBM3E 'foundry-like' moat hinges on long-term deals; but real-world buyer power can still push through price/volume concessions, and Nvidia isn't the only demand source. If Samsung ramps faster and Micron/NV demonstrate substitution, SK Hynix margins may compress quicker than expected. The 4.8x forward multiple assumes resilience in AI capex longer-term; without that, the valuation looks riskier than the memo implies.
Despite the 'Korea Discount' and cyclical concerns, SK Hynix's high market share, Nvidia partnership, and HBM3E's potential as a high-margin, foundry-like product could drive growth. However, risks include cooling AI demand, margin erosion due to supply catch-up, and geopolitical issues.
