5. Decisión Session 9:35 — HOLD
| Factor | Resultado |
|---|---|
| Ranking #4/#5 | MSFT/AMZN — ambos en book |
| Convicción book | High en ambas Positions |
| Thesis | ✅ Validadas — beats AMZN/MSFT confirman cloud/AI thesis |
| Rotación | ❌ No — post-earnings gap no es señal de venta Ackman-style |
| ADD | ❌ No — AMZN +11% gap; cash $25 limita; no chase |
| EXIT | ❌ No — stops no hit ($346.30 MSFT / $217.75 AMZN); Thesis no rotas |
| OPTION-satellite | ❌ No — sin Position abierta; gates risk-policy.options not satisfied (no High+catalyst+thesis doc para nuevo satellite) |
| Macro | ECI 8:30am + Michigan 10am; no día para rotar book concentrado |
Razonamiento Ackman-style: NAV $110.60 (+1,060 bps desde inception) en nuevo ATH. El libro concentra en AMZN (Ackman #2, beat validado) y MSFT (Ackman NEW, beat validado). No vendemos en gap-up post-earnings — exactamente el catalizador que buscábamos (AWS/Azure reacceleration). No añadimos AMZN +11% premarket — preservar cash y evitar chase. MSFT consolidación −0.5% es saludable tras +15% Thu. StockTwits "extremely bullish" AMZN/MSFT — señal social ≤5% peso, Reddit más cauteloso (29%/26% bullish). Default: HOLD para automation-02.
Si automation-02 corre hoy 9:35:
| Action | Probabilidad | Notas |
|---|---|---|
| HOLD | High | Default — book alineado con Thesis; stops intactos |
| ADD | Muy baja | Solo dip post-open; cash $25 limita a ~$15–25 |
| ROTATE | Muy baja | Requiere Thesis rota — beats refuerzan, no debilitan |
| EXIT | Low | Solo si stop $346.30 MSFT o $217.75 AMZN se activa |
| OPTION-satellite | Muy baja | Gates risk-policy.options not satisfied |
Sizing si ADD futuro: max $50/order, min $15, respetar 10% cash floor.
