EV Portfolio Commentary
- TDK +13.1% (top contributor +1.96%) — Biggest winner. TDK/Murata inductor price hikes >100% may be driving re-rating. The ceasefire rally lifted all electronics names
- Sumitomo Electric +12.6% — Continues its momentum (+290% 52W). At 5% weight, contribution is limited
- Kureha +1.8% (weakest) — Still lagging. 1-month return is -10%. The negative FCF and dividend sustainability concern is weighing on the stock. Watch May earnings for FCF recovery
- Hirose +1.6% (weakest) — Flat relative to market. Consistent with our supply chain finding that evidence base is thin. The stock isn't catching the EV rally like peers
- SMM PE 111.8x — The trailing PE keeps expanding (was 103x in yfinance, 27x on StockAnalysis). This appears to be a period where trailing earnings are extremely compressed from metal prices. Forward PE (~15x) is more representative

Nuclear Portfolio Commentary
- Yokogawa +14.3% (top contributor +2.58%) — Massive outperformance. The Rolls-Royce SMR contract (Feb 2026) continues to be re-priced by the market. Our supply chain validation confirmed this is the strongest evidence-backed position in both portfolios
- Kanadevia +12.6% (+20.3% over 1 month!) — Despite our valuation concerns (PE 17x not 10x, negative FCF), Kanadevia is the best 1-month performer across both portfolios. The Fukushima decommissioning narrative + nuclear restart theme is driving this
- Organo +12.3% — Our new addition (GPT recommended) is outperforming. The "every reactor restart = Organo revenue" thesis is being validated by price action. ROE 23.5% justifies the premium
- JSW +3.4% (weakest large position) — The PE 33x + negative OCF concern is keeping a lid on the stock despite the nuclear thesis. Our weight reduction from 25% → 17% was the right call — limited the drag
Supply Chain Evidence vs Performance
Does stronger supply chain evidence correlate with better performance?
| Company | Evidence Score | 1-Week Return | Correlation? |
| Yokogawa | 8/10 (5 confirmed, 3 fresh) | +14.3% | Yes — best evidence, best return |
| Fuji Electric | 9/10 (9 confirmed) | +5.5% | Moderate — strong but not top performer (already fairly valued at PE 19x) |
| TDK | 6/10 (3 confirmed, circumstantial) | +13.1% | No — market rallied on macro (ceasefire), not supply chain specifics |
| Hirose | 5/10 (3 confirmed, still thin) | +1.6% | Yes — weakest evidence, weakest return. Market is discounting the thin EV thesis |
Observation: Yokogawa (best evidence) and Hirose (weakest evidence) show the clearest evidence→performance correlation. TDK's +13% is driven by the broad ceasefire rally and inductor pricing power, not supply chain specifics. Over time, evidence quality should matter more than one week of macro-driven moves.
What Changed Since Our Reports
| Event | Date | Impact |
| US-Iran ceasefire announced | Apr 8 | Nikkei +5.4% single session. Oil -14-16%. All positions benefited from risk-on + lower energy costs |
| Iran accuses US of ceasefire violations | Apr 9 | Nikkei -0.73% pullback. Ceasefire fragility = ongoing volatility risk |
| Nikkei recovers | Apr 10 | +1.84% to 56,924. Market digesting ceasefire as net positive despite uncertainty |
| Kanadevia +20% in 1 month | Mar-Apr | Nuclear infrastructure spending expectations rising independently of ceasefire. Decommissioning thesis gaining traction |
Action Items
| Action | Stock | Trigger | Timing |
| WATCH | Kureha (4023.T) | 1M return is -10%. FCF still negative. If May earnings don't show improvement, reduce from 12% → 7% | May earnings |
| WATCH | Hirose (6806.T) | +1.6% while market did +5%. Weakest performer = evidence thesis being tested. Hold 3% but don't add | Next quarter |
| HOLD | Yokogawa (6841.T) | +14.3% validates the Rolls-Royce SMR thesis. Best performer. Maintain 18% | — |
| HOLD | Organo (6368.T) | +12.3% validates the GPT recommendation to add water/operations exposure. Maintain 10% | — |
| MONITOR | Kanadevia (7004.T) | +20% in 1 month is very fast for a stock we flagged for negative FCF and D/E 0.88. Don't chase. If it pulls back, that's healthy | Ongoing |
| NEXT | All stocks | May earnings season — the single most important event. FCF for JSW, Kureha, Kanadevia, Toyo Tanso is the key metric | Late Apr–May |
