Three Lenses
Lens 01
Constraints Not Routable
Which companies own bottlenecks that cannot be worked around, bypassed, or substituted within 3–5 years? These are monopoly or near-monopoly positions where the laws of physics, chemistry, or installed-base lock-in create pricing power that persists regardless of market cycle.
Lens 02
Revenue CAGR vs. Multiple
Where is the market pricing in too little growth relative to the structural demand curve? The AI chip market is projected to grow at 55–59% CAGR through 2029 (TSMC guidance), but the supply chain behind it has uneven growth profiles — some segments are over-owned, others under-owned.
Lens 03
Mispricing as of Feb 2026
Which stocks trade at forward multiples below what their constraint position warrants? We compare trailing P/E, forward P/E, PEG ratio, and historical average P/E to identify where the market has either over-extrapolated hype or under-appreciated structural scarcity.
Valuation Snapshot — February 2026
Current multiples vs. historical averages and growth rates. The market is paying a massive premium for AI chip design (Nvidia, AMD) while underpricing the physical supply chain that makes those chips real.

Data: MacroTrends, FullRatio, StockAnalysis, GuruFocus, Investing.com, Morningstar as of Feb 10–12, 2026. PEG ratios shown where calculable with TTM earnings growth. Forward P/E based on analyst consensus for next 12 months.
The constraint that gates AI chip deployment in 2026 is not wafer fabrication — it's CoWoS advanced packaging and HBM supply. TSMC's CoWoS capacity doubled to 660K wafers but remains sold out. SK Hynix HBM3E/HBM4 is fully allocated. Every Nvidia Blackwell GPU requires 8 HBM stacks physically bonded via CoWoS. The binding constraint is the marriage of logic + memory, not either alone.
SK Hynix
000660.KS · KRW 886,000
Strong Buy
Constraint: 88% of HBM market, sole primary Nvidia supplier
Trading at 17× trailing vs. 12× 10-year avg — seemingly rich, but earnings just exploded 117% YoY. Forward P/E of ~15× for a company with 47% revenue growth and an unroutable monopoly on the single most supply-constrained component in AI. Memory chip prices rising 90% QoQ in Q1 2026. S&P upgraded to BBB+ with positive outlook. The market still prices SK Hynix as a cyclical memory company, not as the AI infrastructure chokepoint it has become.
Constraint: 92% leading-edge, 75% advanced packaging
28× trailing (vs. 22× historical) looks modestly rich — but TSMC is transitioning from cyclical foundry to AI utility. Revenue CAGR guided at ~25%, AI segment at 55–59%. 2nm mass production starts 2H 2025. Price hikes of 3–10% locked in. PEG of 0.59 suggests the growth isn't fully priced. The geopolitical discount (Taiwan risk) keeps the multiple compressed vs. what this monopoly position deserves.
Micron Technology
MU · $417
Watch → Buy
Constraint play: HBM market share gainer, 21% → 25%+
Micron is the Western world's only HBM producer. Forward P/E of ~12× vs. trailing 39× signals a massive earnings inflection. Up 44% YTD already in 2026 and 323% over one year — the easy money may be made. But Micron's Hiroshima HBM fab and Idaho CHIPS Act investment create structural capacity that's still under-appreciated. Best entry on a memory cycle pullback.
Not a constraint — it's the demand signal, not the bottleneck
Nvidia doesn't own a supply constraint. It designs brilliant chips but depends entirely on TSMC for fab, SK Hynix for HBM, and TSMC CoWoS for assembly. At 46× trailing and $4.5T market cap, the stock prices in strong execution. Earnings Feb 25 will be critical. PEG of 0.72 is reasonable but not cheap. The risk isn't demand — it's that AMD, Broadcom custom ASICs, and hyperscaler in-house chips gradually erode GPU monopoly by 2028–2030.
By 2027, the massive capex wave from TSMC, Samsung, Intel, and Chinese fabs translates into peak equipment revenue. ASML's High-NA EUV (€350M/unit) enters volume deployment. Tokyo Electron's coater/developer monopoly scales with every new fab. The constraint shifts partially from packaging to advanced equipment installation timelines — fabs are announced but take 3–4 years to produce wafers. Equipment makers capture value before fabricators do.
Tokyo Electron
8035.T · ¥40,600

Constraint: 88% global coater/developer market, no substitute
TEL is the Japan-listed equivalent of ASML in its niche — every fab needs its coater/developer systems. At ~35× trailing and guided 15%+ WFE market growth for 2026, it's cheaper than ASML (48×) for a similarly unroutable position. CEO just announced ¥150B buyback. China revenue risk exists but is partially offset by rising demand from TSMC, Intel, and Samsung new fabs. Less geopolitically sensitive than ASML (no export ban controversy).
Constraint: 100% EUV monopoly — the ultimate chokepoint
ASML is the most unroutable constraint in semiconductors: no EUV, no advanced chips, full stop. But at 48× trailing (vs. 36× historical), the market already prices this in. Record Q4 bookings of €13.2B and 17% dividend hike confirm the thesis — but the stock is up to all-time highs. Forward 34× is more reasonable. Best as a core portfolio hold, not a new entry at these levels. Accumulate on dips below $1,200.
Shin-Etsu Chemical
4063.T · ¥5,200
Buy
Constraint: #1 silicon wafer maker, 30%+ global share
The most under-owned name in the AI chip supply chain. Shin-Etsu makes 30%+ of the world's silicon wafers and dominates PVC/specialty chemicals. At ~18× trailing — cheaper than every other company in this analysis — despite owning an unroutable upstream position. Every single AI chip starts as a Shin-Etsu wafer. The market treats it as a boring chemicals conglomerate. That's the mispricing.
Disco Corporation
6146.T · ¥48,000
Watch
Constraint: ~80% of precision dicing/grinding for advanced packaging
Disco dominates the machines that cut and grind silicon wafers — essential for advanced packaging (CoWoS, HBM stacking). As packaging becomes the bottleneck, Disco's equipment is non-optional. At ~42× it's not cheap, but the advanced packaging CAGR of 20%+ through 2030 provides structural tailwinds. Best entry on a semi-equipment sector pullback when the cycle temporarily cools.
By 2028, CHIPS Act fabs in Arizona (TSMC Fab 2/3, Intel) reach volume production. The US goes from 0% to ~15% of leading-edge logic. The question becomes: which companies capture the reshoring value? Not just fab operators — but the construction, specialty gas, chemical delivery, and facility management ecosystems around them. The constraint shifts from "can we build it?" to "can we staff and supply it?"
Binary: If 18A succeeds, it's the only US-owned leading-edge foundry
Intel is a deep contrarian play. If Intel 18A delivers competitive performance and wins foundry customers, Intel becomes the only US-owned company fabricating leading-edge logic on American soil — a national security asset that could command premium pricing and government support indefinitely. If 18A fails, the stock goes much lower. This is a binary outcome with asymmetric upside if positive. Small position sizing is essential.
Constraint: Now operates US fabs + Taiwan fabs = geographic diversification premium
By 2028, TSMC's Arizona Fab 2 (3nm/2nm) reaches volume. This actually strengthens the TSMC thesis: the geopolitical discount that suppresses its multiple begins to shrink as TSMC de-risks itself from Taiwan concentration. TSMC with US production is worth a higher multiple than TSMC without it. Accumulate on any dips caused by temporary Taiwan tension headlines — the re-rating catalyst is already being built in the Arizona desert.
Not a constraint — but the best-positioned custom ASIC alternative to Nvidia GPUs
By 2028, hyperscalers (Google, Meta, Amazon) will have matured their custom chip programs. Broadcom designs these ASICs. This is a demand story, not a constraint story, but it's the strongest structural demand narrative outside Nvidia. At 57× forward P/E, it's expensive — but if custom ASICs take 30%+ of AI compute by 2028 (vs. ~15% today), Broadcom's AI revenue could 3× from here. Wait for better entry below $200.
Advantest
6857.T · ¥9,800
Buy on Dips
Constraint: 50%+ of automated test equipment; every chip must be tested
The most overlooked constraint: every chip must be tested before it ships, and Advantest dominates AI chip testing. As chip complexity rises (2nm, chiplets, HBM stacks), test time per chip increases, meaning Advantest's revenue per chip goes up even if volume is flat. At ~55× trailing it's expensive, but by 2028, the installed base of new fabs globally will create sustained test equipment demand. Buy on any equipment sector correction.
By 2029, AI inference starts migrating from data centers to edge devices. The constraint shifts from training infrastructure (GPUs, HBM) to efficient inference silicon (low-power, analog, automotive). European chipmakers — Infineon, STMicro, NXP — suddenly become relevant as AI chips move into vehicles, factories, and consumer devices where power efficiency, not raw compute, is the binding constraint.
Infineon Technologies
IFX.DE · €33
Buy
Constraint: #1 power semiconductor maker — AI inference needs efficient power delivery
The most overlooked AI play in Europe. Every AI data center, every edge device, every EV needs power management — and Infineon dominates power semiconductors globally. At ~25× trailing, it's far cheaper than any AI-adjacent name. As inference moves to edge, Infineon's SiC/GaN power chips become as critical to AI deployment as GPUs are to training. The market prices Infineon as an auto cyclical, not an AI infrastructure name. That's a multi-year mispricing.
HBM still critical but share eroding — Micron at 25%+, Samsung recovered
By 2029, SK Hynix still dominates HBM but Micron's share has grown to 25%+ and Samsung has resolved its yield issues. The monopoly premium compresses. HBM6 is the new frontier, and Korean suppliers retain technology leadership, but the pricing power of 2025–2027 era begins to moderate. Hold existing positions; trim if P/E re-rates above 25×.
Not a constraint — but the IP architecture behind 99% of edge AI chips
ARM licenses the processor architecture used in virtually every smartphone, IoT device, and increasingly AI edge chips. As inference shifts to edge, ARM's royalty-per-chip model scales with volume. Extremely rich valuation (100×+ P/E) makes timing difficult, but the structural position is near-monopolistic. Best as a long-term watch for entry below $120.
No constraint — and sandwiched between Nvidia (top) and custom ASICs (bottom)
AMD's structural problem: it's the #2 GPU maker in a market that's consolidating toward Nvidia at the top and custom ASICs (Broadcom/Google/Amazon) at the bottom. At 78× trailing P/E with 30% growth, the PEG ratio is unattractive vs. peers. By 2029, custom chips may have taken significant share from general-purpose GPUs, and AMD — unlike Nvidia — lacks the software ecosystem (CUDA) to maintain lock-in. High valuation + structural squeeze = avoid.
Global semiconductor revenue hits $1T+. AI chip revenue approaches $500B–$1T depending on definition. The supply chain has partially de-risked from Taiwan, but the core structure remains: design (US), equipment (EU/Japan), materials (Japan), fabrication (Taiwan > US), memory (Korea > US). The winners over 2026–2030 were determined by who owned the constraints — not who had the best narrative. The cheapest constraint-owners in 2026 delivered the best risk-adjusted returns.
The 2030 Core Portfolio — Constraint Owners
If you bought in Feb 2026 and held
Long-Term Hold
The stocks that should have outperformed over the 2026–2030 cycle are those that (a) owned non-routable constraints, (b) traded at reasonable multiples relative to their structural growth, and (c) benefited from the AI buildout regardless of which chip designer "won." This is the shovel-seller portfolio for the AI gold rush — and the shovels were priced cheaper than the gold in February 2026.

The Constraint Thesis, Summarized
The AI chip buildout is a $500B+ annual market by 2026, growing to $1T by 2030. The market has allocated the largest premiums to the demand-side stories — Nvidia (46×), AMD (78×), Broadcom (57×). But the demand side is where competition increases over time: custom ASICs, in-house hyperscaler chips, and open-source alternatives all chip away at GPU monopolies.
The supply-side constraints — the physical chokepoints that cannot be routed around — trade at structural discounts to the demand-side narratives. SK Hynix (17×) owns the HBM gate. Shin-Etsu (18×) makes the wafers. Tokyo Electron (35×) makes the coaters. Infineon (25×) makes the power chips. TSMC (28×) does the fabrication. These companies don't need any particular chip designer to "win" — they win regardless, because every AI chip, no matter who designs it, must pass through their constraints.
The mispricing as of February 2026 is clear: the market pays 3–4× higher multiples for companies that face increasing competition (demand side) than for companies that face zero competition (supply side). The constraint owners are the better risk-adjusted bet over any 3–5 year holding period.
The trade: underweight the chip designers, overweight the constraint owners.
