Changes from v1: Fixed 5 gaps identified in Iteration 1
YOUR TASK
Produce a COMPLETE deep due diligence report on the given Japan investment theme.
PHASE 1: Stock Discovery (aim for 15-25 stocks, NOT just 5-10)
Approach A: Direct search
Search for Japanese companies in this sector. Search in English AND Japanese.
Approach B: T-glass method (value chain tracing)
1. Identify the GLOBAL leaders in this industry (any country)
2. Trace their value chain BACKWARDS from end product to raw materials
3. At EACH layer ask: "Who is the dominant Japanese supplier? Is the position irreplaceable?"
4. Search in English, Japanese (日本語), AND Chinese (中文) — Taiwan/China sources (DigiTimes, TrendForce) often have the best supply chain intelligence
5. Look for MONOPOLY indicators: >60% share, sole-source, no qualified alternative
IMPORTANT: Cover ALL segments of the value chain
- Don't stop at the obvious players — dig into materials, niche components, specialty chemicals
- Include adjacent segments: maintenance, decommissioning, medicine, fusion (for nuclear)
- Include upstream materials that are easy to miss (glass cloth, resins, gases, graphite)
IMPORTANT: Check cross-theme connections
- Does this theme share supply chain with other themes? (e.g., nuclear I&C → semiconductor equipment)
- Are there restocking cycle plays that overlap? (e.g., passive components in both AI and nuclear)
Rate each position:
★★★★★ MONOPOLY (>80% share, impossible to replicate in <10yr)
★★★★ DOMINANT (>50% or duopoly, very difficult to replicate)
★★★ STRONG (20-50%, defensible but competitors exist)
★★ COMPETITIVE (<20%, multiple competitors)
★ WEAK (no structural advantage)
PHASE 2: Financial DD — EVERY metric for EVERY stock
For EACH company, search StockAnalysis.com: "stockanalysis.com/quote/tyo/{TICKER}/statistics/"
ALL of these metrics are REQUIRED (mark N/A if truly unavailable):
- PE (trailing)
- Forward PE
- P/B ratio
- ROE (%)
- Operating Margin (%)
- Debt/Equity ratio
- Dividend Yield (%)
- Free Cash Flow
- Market Cap
- Revenue (TTM)
- Revenue Growth (YoY %)
- 52-week price change (%)
Present as a comparison table with ALL stocks and ALL metrics.
PHASE 3: Per-Stock Analysis
For EACH company provide:
- Thesis (WHY this stock — be SPECIFIC, name products, contracts, market share numbers)
- Risk (what could go wrong — specific, not generic)
- Monitoring trigger (if X happens, do Y)
- Supply chain (named customers AND suppliers, with evidence: confirmed/probable/inferred)
- Key dates (next earnings, catalysts, regulatory milestones)
- Nuclear/AI exposure % (what fraction of total revenue comes from this theme?)
PHASE 4: Validation
- Cross-check key metrics against a second source (Yahoo Finance, Kabutan)
- Search for RECENT catalysts (last 3 months) — contracts signed, policy changes, major events
- Document any discrepancies in an errata table
PHASE 5: Scoring & Ranking
Score each stock on 4 dimensions (1-5 each, max 20):
- Financial Quality (ROE, margins, balance sheet)
- Theme Purity (% of revenue from this theme)
- Moat Depth (market share, replaceability)
- Valuation (PE relative to growth, risk/reward)
Assign conviction: HIGH (score 14+) / MEDIUM (10-13) / LOW (<10)
PHASE 6: Competitive Comparison
For each value chain layer, compare:
Fill in company name, market share, and who has the EDGE.
Identify Japan's TRUE chokepoints (positions that cannot be replaced within 10 years).
OUTPUT FORMAT
Your report MUST include:
1. Macro context (industry status, policy, demand drivers)
2. Value chain map with Japan's position at each layer
3. Full comparison table (ALL stocks, ALL 12 metrics)
4. Per-stock analysis (thesis/risk/trigger/supply chain/key dates)
5. Scoring matrix (4 dimensions × each stock)
6. Conviction tiers with reasoning for each
7. Japan vs global competitive matrix
8. Recent catalysts (last 3 months)
9. Cross-theme connections
10. All sources cited with URLs
