Semiconductor Leaders — SK hynix Anchor, Post-Blow-Off Price Paths (Semi Leaders Sector)

Executive Summary & Action Plan

Verdict

SELL / UNDERWEIGHT memory, stand aside elsewhere — no Top Pick. All seven leaders trade at or above IWANNAVY fair value after the wildest week in Korean market history (KOSPI +17.91% record day, SK hynix's first-ever limit-up, then −8.8% Monday). The Q2'26 prints added real cash-flow evidence — we raised SK hynix to ₩1,231,000 and Samsung to ₩221,000 — but SK hynix still sits 27% above its mark, Micron 65% above, and the only positive gap in the complex is NVIDIA at +4.6%, too thin to act on. Notably, last week the market twice found our value zone: Samsung's 7/30 trough (~₩208,000) traded through the new ₩221,000 anchor and SK hynix's ₩1,322,000 trough came within 7% of its new mark — then both rebounded ~30% in one session. The tape is discovering the same normalization arithmetic we are; it just hasn't stayed there yet.

Price ₩1,567,000 | Market cap ₩1,112.3T | Target ₩1,231,000 | Upside −21.4% IWANNAVY Fair Value (re-underwritten 2026-08-03 on the Q2'26 print) · price as of 2026-08-03 close · Street consensus ₩3,189,340 (n=37, reference; fresh post-print domestic median ≈ ₩2.9M (E), 8 of 9 covering brokers cut on 7/29–30) — we sit ~61% below Street because consensus capitalizes a 76% operating margin as durable where we normalize to 35% and credit the boom only through an explicit discounted cycle-surplus bridge

Abstract

We re-underwrote the seven-name semiconductor leadership complex after a five-session round trip without precedent: SK hynix printed a record Q2'26 that still missed consensus (revenue ₩79.3T, operating profit ₩60.5T at a 76% margin), Samsung confirmed the largest operating profit in its history (₩89.5T, semiconductors contributing 99.7%), KOSPI then rose a record +17.91% in one session — SK hynix's first-ever limit-up, on record ₩7.28T foreign buying — and gave back 8.8% on Monday as foreigners flipped to net sellers. New cash-flow evidence lifts SK hynix's fair value to ₩1,231,000 (from ₩1,170,000; realized +₩34.4T Q2 free cash flow and uncapped LTAs) and Samsung's to ₩221,000 (from ₩202,000; a management-quantified supply wall into 2028). Micron $500, NVIDIA $210, TSMC $310, Broadcom $320 and ASML $1,510 are affirmed. The median gap to fair value is −18%; every memory name remains above normalized value while 2027 HBM4 contract talks are moving up, not down — fattening the bull tail. Rating stays SELL/UNDERWEIGHT memory, no Top Pick; principal risks are an LTA floor-price regime change and Korea's leveraged-flow plumbing.

Forecast Path

The path below prices SK hynix (000660.KS), the user-anchored name and the sector's highest-beta expression. Scenario weights are judgmental (Bear 30 / Base 45 / Bull 25 — not equal-tails: spot sits 27% above the base anchor, the left tail is mechanically amplified by Korea's leverage drainage, and Samsung's shortage-to-2028 guidance plus floor-priced LTAs make the bull tail too real for a token weight). Bands are judgmental and uncalibrated; realized volatility is above 150% annualized (E).

Action Plan

Do not chase at ₩1,567,000; trim into strength at the ₩1,616,000 pivot and above, and stage re-entry only into the fair-value zone. The ladder blends to ≈₩1,164,000 entry: risk to the ₩890,000 structural stop is −23% against +39% back to the pivot (R/R ≈ 1.7:1) and +132% to the bull anchor (tail R/R ≈ 5.6:1).

The ranking below is the report in one frame: upside to normalized IWANNAVY fair value, not to Street targets.

• Prob-weighted 12M return (anchor): −11.4% | P(house view wrong): 0.55 (from 0.62 on 7/21 — timing risk, not arithmetic) | Confidence: Medium-High on the valuation framework, Medium on cycle timing

What Happened / State of the Sector

Six sessions rewrote the tape. CXMT debuted +466% on STAR (7/27) to a ~$523B market cap — China's most valuable listed company on ~8% DRAM revenue share — and Korea crashed the next day (Samsung −13%, SK hynix −14%, ₩3.2T foreign selling in hynix alone). SK hynix's Q2'26 print (7/29) was a record that missed: revenue ₩79.32T vs ~₩83.7–84.7T consensus, operating profit ₩60.54T vs ~₩63.7–64.9T, the miss attributed by Korea Investment to HBM shipment-timing deferral, with no shareholder-return announcement; the stock closed −9.61% with a −19.6% intraday low. Samsung's confirmed print (7/30) went the other way: ₩89.49T operating profit (+1,814% YoY), DS division at a 70% margin, DRAM ASP +40–45% QoQ — and management guided the shortage to worsen in 2027 and persist into 2028, with Q3 HBM4 revenue tripling. Friday (7/31) delivered the largest single-day KOSPI gain in its 46-year history (+17.91%) on record ₩7.28T foreign buying; hynix hit its first-ever +29.95% limit-up. The same day in New York, Micron fell 5.9% as Michael Burry disclosed a larger short and Apple's CEO — calling memory pricing a "once-in-a-hundred-year flood" — said more DRAM suppliers would be a positive. Monday gave back 8.8% on profit-taking (~40% weight), the China supply narrative including domestic immersion-DUV mass production reports (~20%), and the US memory fade (~15%); no new fundamental event printed on 8/3.

The margin picture now includes Q2'26, and it is still a blow-off, not a plateau. Micron's latest print (fiscal quarter ended May) is one period staler than the Korean pair.

SK hynix's income flow shows both the operating leverage and the one-off: ₩33.4T of the "other & tax" line is dominated by ~₩63.3T of investment-asset gains (Kioxia stake disposal and mark-up) less tax — net income of ₩93.9T is not earnings power; operating profit of ₩60.5T is.

Pricing signals are aging but not broken: 3Q26 server-DRAM contracts settled +13–18% QoQ (down from +58–63% in 2Q — the momentum peak has printed), PC DRAM contract gains are narrowing into a buyer-seller stalemate, NAND wafer spot has fallen two consecutive prints while NAND contract is still guided up — the first late-cycle contract/spot scissor — and customer inventory sits at 7–9 weeks (stale 7/5 datapoint) against the 10-week mechanical trigger. Supplier inventory at 3–5 weeks is the one gauge showing zero cycle-top behavior.

What to Watch Now

• TSMC July revenue (~8/10): ≥NT$460B (+42% YoY) keeps the trend hot; <NT$400B is the first digestion signal. The 3M rolling YoY is ~+36% and accelerating.
• NVIDIA Q2 FY27 (8/26): guide $91B±2%, street ~$93.5B. Bull: ≥$95B print, gross margin ≥75%, Q3 guide ≥$100B. Bear: Q3 guide <$95B or Rubin-transition pause language.
• Broadcom Q3 (9/3): AI semis vs $16B guide; the mover is the Q4 AI guide — ≥$20B (E) keeps the FY27 >$100B glidepath, <$19B (E) breaks it.
• Micron FQ4 (~9/23–29, unconfirmed): the single cleanest peak-dating instrument in the complex. In-line FQ4 (~$50B) plus an FQ1'27 guide below $50B = first sequential decline = cycle peak dated.
• 4Q26 contract round (Sep–Oct): the first flat-or-down quarter is the cycle-top signal; every current preview points to a smaller increase, not a decline.
• Korea plumbing drainage: leveraged-ETF deposit rule effective 7/31, collateral-recognition ban ~8/19, a statutory emergency-power bill pushed over the weekend — each step mechanically drains leveraged demand from two stocks that are ~21% of KOSPI.

What to Watch Next (Technology)

• 2027 HBM4 contract ASPs — the thesis breaker, now moving against us in direction. Secondary-source reporting has HBM4 going from ~$2/Gb in 2H26 to $4–5/Gb in 2027; SK hynix says 2027 volume-and-price talks with 11 LTA customers are "proceeding smoothly" with the conventional-DRAM surge feeding the negotiation, and Samsung says its 2027 HBM supply discussions are already concluded. Signed contracts at ≥2x 2026 ASP, disclosed at the late-October Q3 prints, would force our normalization timeline out 12–18 months.
• HBM4E and the share fight: Samsung shipped industry-first HBM4E samples, guides HBM4 to >60% of its HBM revenue in 2H26 and targets HBM share equal to its DRAM share (~30%+, vs 17% in Q2) — against SK hynix at 62% and Micron at 21%. Samsung reportedly still lacks an NVIDIA HBM4 volume order (7/17); watch that gate.
• LTA regime change: SK hynix removed price ceilings (floors only, 3–5yr tenors); Samsung is contracting ~2/3 of output on 5yr+ terms with upfront payments and floors; Micron's 16 SCAs keep caps frozen at Q2'26 market prices. If floors near current levels survive a downturn, the mid-cycle framework itself resets — this is risk H1 to every mark below.
• China supply: CXMT's ~RMB 29.5B post-IPO program is mostly process migration into DDR5/server, not greenfield; YMTC targets ~500K wpm with fab 3 producing by end-2026; domestic immersion DUV entered mass production (~5 units 2026, four generations behind ASML). CXMT remains off the BIS Entity List; the MATCH Act has not reached the floor. Merchant HBM gap: still 4–6 years.

Fair Value Notes

Marks are log-medians of DCF, EV/EBITDA and EV/FCF legs, cycle-normalized; revisions require cash-flow evidence, never price momentum. The 8/3 session contributed nothing to any mark.

• SK hynix (000660.KS) ₩1,231,000 (8/3, supersedes ₩1,170,000 of 7/21) — Q2 realized +₩34.4T FCF (net cash ₩35.0T→₩69.4T) added to all legs; cycle-surplus bridge ₩62.8T→₩68.3T (+₩13.0T LTA uncap capture, +₩2.0T HBM4 revenue slip into 2H, −₩6.5T OP mark-to-actual, −₩3.0T high-₩40T capex guide). Normalized 35% OM anchor unchanged — 76% margins remain the conventional-DRAM squeeze, and HBM4 is triple-qualified.
• Samsung Electronics (005930.KS) ₩221,000 (8/3, supersedes ₩202,000) — bridge ₩104.9T→₩114.9T on the management-quantified supply wall (>3.5-year fab lead times, no material supply growth until 2028; Q3 HBM4 ~3x QoQ); realized Q2 FCF ~+₩53T (derived, E). DX's first-ever loss (−₩0.8T) is the memory windfall's mirror image and self-reversing. Least-stretched name in memory.
• Micron (MU) $500 affirmed (7/21) — no cash-flow news since 6/24; SCA price caps frozen at Q2'26 market levels mean MU contractually surrendered the uncapped upside hynix gained. Weakest cash capture of the peak: 0.8% FCF yield, 119x EV/FCF.
• NVIDIA (NVDA) $210 · TSMC (TSM) $310 · Broadcom (AVGO) $320 · ASML $1,510 — all affirmed with legs within 1–4% of marks. NVIDIA is the cheapest growth-adjusted name (19.8x fwd EV/EBITDA, 22.5x fwd EV/FCF at the mark); TSMC's July-negotiated 2027 wafer price hikes (5–10% plus HPC surcharges) are flagged as upside risk to the next refresh; ASML remains the richest (29.3x fwd EV/EBITDA at mark) with bookings disclosure retired.

• Thesis breaker: signed 2027 HBM4 contracts at ≥2x 2026 ASP with conventional-DRAM floors written into CSP agreements, disclosed at the hynix/Samsung Q3'26 prints (late October).

Catalysts & Risks

The catalysts are dated and falsifiable; the risks are ranked by 12M impact on the house view.

Falsification & Review Rules

• The SELL is wrong if 2027 HBM4 contracts are signed (not merely discussed) at ≥2x 2026 ASP and conventional floors survive into CSP contracts: lift normalized OM anchors ~+5pp and re-mark every memory FV upward. Do not press shorts into the Q4'26 HBM pricing window.
• The timing is wrong (glide, not glut) if 4Q26 and 1Q27 contract prints stay positive while customer inventory holds below 10 weeks: convert the stance to time-boxed underweights; the carry cost of "early" is the main P&L risk.
• The house view is confirmed on the first QoQ blended-ASP decline, or on an in-line Micron FQ4 with an FQ1'27 guide below $50B.
• Anchor ladder invalidation: a weekly SK hynix close below ₩890,000 opens the bear path toward ₩532,000; a reclaim of ₩1,616,000 with foreigners returning as net buyers is the repair signal — stop pressing.
• No-pick review: NVIDIA is the conditional quality candidate; +4.6% to mark does not clear the entry bar. Revisit after 8/26.
