Changes Summary
| Ticker | Company | Themes | Key Changes | Thesis Status |
|---|---|---|---|---|
| 6857.T | Advantest | AI / Semiconductor | Teradyne GPU qualification did NOT hit H1 2026 (risk pushed to H2). SK Hynix in-house HBM4 tester confirmed but scope limited (SiP ~10% TAM). VOICE 2026 confirmed May 18-20. PE normalized 68.6→63.0. | HOLD (qualified UPGRADE on post-earnings weakness) |
| 6954.T | Fanuc | Robotics | China +87% YoY confirmed (Morningstar Q2). $90M Michigan factory (tariff hedge). NVIDIA Physical AI partnership LIVE. Section 232 May 30 = binary event. PE 35.6→37.9, ROE 9.4%→8.6%. | HOLD (defensive — no adds pre-May 30) |
| 8035.T | Tokyo Electron | Semiconductor / AI | TSMC Q1 2026 capex $52-56B confirms foundry demand. Samsung/SK Hynix HBM4 ramp validates memory tools. Austin RiverSouth HQ inaugurated. AI mix on-track 40% FY2026. PE 40.2→43.7. | UPGRADED |
1. Advantest (6857.T) — HOLD (qualified UPGRADE)
Thesis Validation
Monopoly position confirmed. FY2025 guidance ¥1.07T revenue (raised 3x) and 42.4% op margin remain base case. Capacity ramp to 5,000 systems/yr by Mar 2027 on-track; potential 7,500-system stretch target. TSMC CoWoS packaging booked through 2026 and SK Hynix/Micron HBM supply sold out → test demand is supply-constrained through 2026.
What Changed Since Last DD (2026-04-14)
Teradyne NVIDIA GPU qualification — did NOT close H1 2026. Search through Apr 17 shows Teradyne collaborating with NVIDIA on Physical-AI / robotics, not core merchant GPU test. Risk deferred to H2 2026, not materialized.

SK Hynix in-house HBM4 tester — CONFIRMED (Jan 2026) but narrower than feared. SK Hynix qualified a proprietary HBM4 system-level tester Jan 2026 with TSMC. This is SiP/post-integration tester, not SoC replacement. Estimated TAM impact: -2 to -3%.
NVIDIA capex — structurally bullish. Q1 FY2026 data-center rev $62B; hyperscaler capex ~$700B in 2026 (Meta $135B, Google $185B) vs ~$400B in 2025.

| Market cap | ~¥22.1T | ¥20.79T | ¥20.84T | ¥20.8T |
Updated WHY / RISK / TRIGGER
WHY: SoC ATE monopoly (~58-60% share, ~70% in AI-GPU niche) with 49% ROE and 43% op margin. Supply-constrained by TSMC/SK Hynix test demand. Teradyne qualification deferred; SK Hynix in-house tester narrow.
RISK: (1) PE 63x / PB 26x leaves no margin for NVIDIA capex deceleration. (2) Teradyne merchant-GPU qualification now H2 2026 binary event. (3) Capacity at 5K systems assumes >80% attach; any slowdown dilutes margin 300-500bps. (4) Convertible bond dilution overhang.
TRIGGER: Apr 27 FY2026 initial guidance — mid-teens+ growth = add on weakness. Flat/"digesting" language = trim. VOICE 2026 (May 18-20) new-product announcements.
Key Dates
- 2026-04-27 (earnings): FY2025 + FY2026 initial guidance — critical
- 2026-05-18 to 05-20 (catalyst): VOICE 2026, Scottsdale
- 2026-06-30 (rebalance): Semiannual rebalance
- 2026-07-15 (monitoring): NVIDIA Q2 FY2027 capex commentary
- 2026-12-31 (monitoring): Teradyne merchant-GPU qualification decision window
2. Fanuc (6954.T) — HOLD (no adds pre-May 30)
Thesis Validation
Picks-and-shovels monopoly intact. ~60% global CNC share, ~25% industrial robot share, zero-debt. FY2026 ordinary income guidance ¥2,148B (+9.2% YoY). Q3 cumulative +14.2% YoY.
What Changed Since Last DD (2026-04-16)
China +87% YoY robot sales — validated. China now >25% of robot revenue. March 2026 China mfg PMI 50.4 (expansion, from 49.0 Feb). Rebound is happening.
NVIDIA Physical-AI partnership LIVE (Mar 16, 2026). Jetson + Isaac Sim + Omniverse integration into Fanuc robots and ROBOGUIDE simulator. MODEX 2026 (Apr 13-16) showcased CRX-30iA on OTTO 600 AMR.
$90M Michigan plant (Mar 24, 2026). 840K sq ft, 225 jobs, completion late 2027. Management betting its own capital against Section 232 tail risk.
Section 232 deadline May 30 — still binary. Commerce report on robots/CNC due May 30, 2026. 25% tariff could cost 5-10% of FY2026 EPS. No leaked Japan exemption.
Hannover Messe 2026 (Apr 20-24). Fanuc confirmed exhibitor; watch for CRX/humanoid demos during show window.

| Market cap | — | ¥5.91T | — | ¥5.9T |
Updated WHY / RISK / TRIGGER
WHY: ~60% CNC / ~25% robot global share, zero debt, 20.5% op margin. China +87% YoY validated. NVIDIA Physical-AI partnership accretive. Michigan plant = self-funded tariff hedge.
RISK: (1) Section 232 binary — May 30 Commerce recommendation + ~90-day implementation. 25% tariff = 5-10% FY2026 EPS hit. (2) Japan exemption status unknown. (3) Apple/CRX pipeline still unconfirmed in filings. (4) ROE 8.6% below cost of capital.
TRIGGER: Apr 25 earnings — FY2027 guidance + tariff-scenario language critical. May 30 Section 232 = add-or-trim inflection. Hold into May 30; do NOT add on earnings beat until tariff resolves.

3. Tokyo Electron (8035.T) — UPGRADED
Thesis Validation
#3 global WFE position intact, AI pivot accelerating. Coater/developer ~90% share uncontested. FY2025 revenue ¥2.43T (+32.8% YoY), OP +50.2%, NI +49.5% — all-time highs. FY2026 guidance ¥2.35T (+6.9%) with H2 expected as record. AI mix on-track 40%.
What Changed Since Last DD (2026-04-12)
TSMC Q1 2026 capex high-end $52-56B (Apr 16). CEO C.C. Wei flagged 2026 revenue >30% growth; Q2 NT$39-40.2B (+10% QoQ). TSMC = TEL's largest customer; structurally bullish for foundry equipment demand into 2026-2027.
Source: https://www.cnbc.com/2026/04/16/tsmc-q1-profit-58-percent-ai-chip-demand-record.html
Samsung/SK Hynix HBM4 ramp. Samsung targeting ~250K wafer/mo by end-2026 (+47%); HBM4 mass production Q2 2026; HBM shipments tripling in 2026. Memory equipment ~40% of TEL revenue.
SEMI 2026 WFE forecast +9.0% to $135.2B, memory equipment +12.7% to $15.7B. Stronger tailwind than prior framing.
ASML Q1 2026 raised 2026 guidance to €36-40B; memory 51% of sales; China fell to 19%. Parallel indicator for Japanese WFE peers.

BIS enforcement intensity up. Applied Materials $252M penalty, Cadence $95M (Feb 2026). Japanese firms historically under more lenient rules — watch METI alignment.

Share price ¥44,350 (down from Feb peak ¥46,600) — pullback creates entry.
Updated WHY / RISK / TRIGGER
WHY: #3 global WFE, ~90% coater/developer monopoly. FY2025 all-time-high rev/OP/NI. TSMC $52-56B 2026 capex + Samsung/SK Hynix HBM4 ramp = sustained demand through H2 2026 and 2027. AI equipment 40% of sales de-risks China 30% exposure. Record dividend ¥601/share +23% YoY, zero-debt.
RISK: (1) China 30% exposure still tail risk if METI aligns fully with BIS. (2) PE 41.9x / PB 10.5x leaves little room if FY2026 H1 weakness extends. (3) Memory capex tied to NVIDIA GPU demand. (4) Q3 FY2026 revenue -15.7% YoY; H2 ramp must materialize.
TRIGGER: May 12 FY2025 confirmation + FY2026 initial guidance — watch H2 ramp language and AI-equipment % disclosure. Add on post-earnings dip to ¥42-43K. Trim if China revenue moves toward 40% or TSMC capex guidance is cut.
Key Dates
- 2026-05-12 (earnings): FY2025 + FY2026 initial guidance — critical
- 2026-06 (catalyst): Annual shareholder meeting — dividend policy, capex
- 2026-06-30 (rebalance): Semiannual rebalance
- 2026-08-06 (earnings): FY2026 Q1 — first H2 ramp validation
- 2026-09 (monitoring): SK Hynix HBM4 mass production phase-2
- 2026-12 (monitoring): 2027 capex guidance pre-announcement window
