Is SKHYV a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for SK hynix (SKHYV) rests on HBM leadership in the AI memory cycle: SK hynix held about 58% of the HBM market in early 2026 and was the lead HBM supplier to Nvidia, including for next-generation HBM4 used in the Rubin platform. Revenue (TTM, approx) is ~$95 billion (KRW ~132 trillion). If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Memory is a deeply cyclical industry, and the current supercycle margins (operating margins around 70%) are far above the long-run average, so earnings can fall hard if AI capex cools or if Samsung and Micron close the HBM gap and add supply. Whether SKHYV is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
SK hynix is one of the three companies that dominate the global memory-semiconductor industry, alongside Samsung Electronics and Micron. It designs and manufactures DRAM (server, PC, mobile, and graphics memory), NAND flash, and solid-state drives, and it has become the clear leader in high-bandwidth memory (HBM), the stacked DRAM that sits next to AI GPUs. As of mid-2026 SK hynix held roughly 58% of the HBM market and was the primary HBM supplier to Nvidia, which gives it an outsized role in the AI hardware supply chain. The SKHYV listing is an ADR program (each common share is represented by roughly ten ADRs) that raised about $26.5 billion, one of the largest U.S. debuts ever by a foreign company. The investment picture is defined by the memory supercycle. AI demand pushed SK hynix to record results: FY2025 revenue of about KRW 97 trillion (~$68 billion) and net profit near KRW 43 trillion (~$31 billion), followed by a Q1 2026 quarter with revenue up roughly 198% year over year and operating margins around 70%. The bull case is continued HBM dominance and pricing power; the bear case is that memory is historically cyclical, so today's supercycle margins can compress sharply if supply catches up or AI capex slows. SKHYV lets U.S. investors hold that exposure directly on the Nasdaq rather than through the Korea-listed shares.
What's the case for buying SKHYV?
1. HBM leadership in the AI memory cycle
SK hynix held about 58% of the HBM market in early 2026 and was the lead HBM supplier to Nvidia, including for next-generation HBM4 used in the Rubin platform. HBM revenue more than doubled year over year in 2025 and carries much higher margins than commodity DRAM. This position is the single biggest driver of the company's record profitability.
2. Broad memory franchise beyond HBM
Beyond HBM, SK hynix is the number-two DRAM maker overall (~29% share) and a top-tier NAND and enterprise-SSD supplier, with NAND revenue also hitting records in 2025 on AI-server storage demand. A tight overall memory market lifted pricing across DRAM and NAND. That breadth means the AI tailwind extends past just the HBM line.
3. Nasdaq listing and shareholder returns
The SKHYV ADR gives U.S. investors direct access and is intended to narrow the so-called Korea discount by broadening the shareholder base. The company paired its record 2025 results with its highest-ever shareholder returns via dividends and buybacks. The ~$26.5 billion raised is among the largest foreign debuts in U.S. market history.
4. Capacity and technology roadmap
SK hynix is investing heavily to expand advanced DRAM and HBM capacity, including HBM4 ramp and partnerships on base-die manufacturing. Execution on next-generation nodes is what protects its lead against Samsung and Micron. Heavy capital spending is both the growth engine and a source of cyclical risk.
What are the risks to SKHYV?
Memory is a deeply cyclical industry, and the current supercycle margins (operating margins around 70%) are far above the long-run average, so earnings can fall hard if AI capex cools or if Samsung and Micron close the HBM gap and add supply. Customer concentration is a real risk given how much of HBM growth is tied to Nvidia. The stock had already risen sharply (the Korea-listed shares were up several hundred percent over the prior year heading into the listing), so a lot of good news is arguably in the price. As an ADR, SKHYV carries currency (Korean won), foreign-tax, and Korea-specific governance considerations, and the when-issued SKHYV ticker converts to SKHY around July 13, 2026. Geopolitical exposure, including China operations and U.S. export controls on advanced chips, adds further uncertainty.
How is SKHYV valued? (as of JULY 2026)
Snapshot for SKHYV as of July 2026, sourced from Yahoo Finance and may be delayed. Valuation figures move with price and earnings; verify the current numbers with your broker before deciding.
- Revenue (TTM, approx): ~$95 billion (KRW ~132 trillion)
- FY2025 revenue: ~$68 billion (KRW ~97 trillion, record)
- FY2025 net profit: ~$31 billion (KRW ~43 trillion)
- HBM market share: ~58% (global #1)
- IPO / debut: ~$149 ADR offer, opened ~$170, raised ~$26.5B
- Market cap (approx): ~$1 trillion (varies by source)
SK hynix posted record results as AI demand drove a memory supercycle, with FY2025 operating margin near 49% and Q1 2026 operating margin around 70%. Reported trailing P/E was roughly 20 while forward P/E screened far lower (~5 to 6), reflecting expectations that earnings stay elevated. All figures are approximate as of JULY 2026 and convert from Korean won, so exchange rates and the when-issued nature of the SKHYV ADR affect the precise numbers.
How do you decide if SKHYV is a buy?
Rather than asking whether SKHYV is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold SKHYV indirectly through an index or sector ETF before adding more.

The bottom line on SKHYV
The bottom line: SK hynix's story right now is HBM leadership in the AI memory cycle, with revenue (ttm, approx) at ~$95 billion (KRW ~132 trillion). If you believe that narrative continues, the call is about sizing SKHYV sensibly and checking overlap with what you own; if you doubt it (the risk: memory is a deeply cyclical industry, and the current supercycle margins (operating margins around 70%) are far above the long-run average, so earnings can fall hard if AI capex cools or if Samsung and Micron close the HBM gap and add supply.), it is not for you. Decide from the thesis, not the ticker. Walnut is not an investment adviser.
