SKHY vs SKHYV: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. SKHY and SKHYV share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined SKHY and SKHYV exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

SK hynix is a South Korea-based semiconductor company that designs and manufactures memory chips, primarily DRAM (including high-bandwidth memory, or HBM) and NAND flash storage. Its products sit inside data-center servers, AI accelerators, smartphones, and PCs. The company is the number-one supplier of HBM, the stacked DRAM that pairs with Nvidia and other GPUs to power AI training and inference, holding roughly 57 to 62 percent of the HBM market, and it ranks number two globally in both DRAM (~29 percent) and NAND (~18 percent). It listed American depositary shares on the Nasdaq under the ticker SKHY in July 2026 (trading briefly as SKHYV on a when-issued basis first).

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• SKHY drivers: HBM leadership into the AI buildout; Record profitability and net cash.
• SKHYV drivers: HBM leadership in the AI memory cycle; Broad memory franchise beyond HBM.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Memory is a deeply cyclical, commodity-influenced industry, so the record ASPs, margins, and profits seen in 2026 could reverse quickly if AI capital spending slows or if rivals add supply. For 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.

Pick SKHY if you believe its drivers more; SKHYV if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the SKHY and SKHYV guides.

SKHY. SK hynix posted record 2025 results (~₩97 trillion revenue, ~₩47 trillion operating profit) and then set fresh quarterly records in Q1 2026 as HBM and server-DRAM demand and prices climbed. Despite the surge in earnings, the shares trade at a low single-digit-to-mid-single-digit forward P/E, well below the broad semiconductor sector, which reflects the market's memory-cycle skepticism. Figures are approximate and converted from Korean won at prevailing rates.

SKHYV. 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.

Headline figures (approximate, July 2026): SKHY shows revenue (ttm) ~₩132 trillion (~$98 billion), fy2025 revenue ~₩97.1 trillion, q1 2026 revenue ~₩52.6 trillion (up ~198% YoY), q1 2026 operating margin ~72%; SKHYV shows 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).

SKHY and SKHYV are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined SKHY and SKHYV exposure against your real portfolio. It is not an investment adviser.
