|---|---|---|---|
| AMZN S2 | +0.20% | -0.85% | Mismatch: The rationale is fundamentally an NVDA story (valuation compression, sector rotation), with AMZN only implied as a second-order beneficiary via its in-house chip effort — yet the trade bought AMZN on a FRESH verdict as if it were the direct subject. The outcome confirmed there was no real catalyst for AMZN: the position never got more than +0.20% of traction and bled to -0.51%. Improvement: Add an entry rule requiring the traded ticker to be the primary subject of the analyst thesis, not an inferred beneficiary; if the signal is derivative (e.g., "X's weakness helps Y"), downgrade the verdict from FRESH to something requiring secondary confirmation (e.g., ticker-specific news or momentum) before entry. |
| MU S3 | +5.89% | -0.36% | Rationale-to-ticker mismatch: The thesis is entirely about Nvidia's valuation compression, yet the trade bought MU — the "sector rotation toward memory" clause is doing all the work, and that's a stretch, not a REPRICING signal on MU itself. The trade happened to work (+3.32), but it captured only ~0.4% of a move that reached +5.89% unrealized, so the exit gave back nearly all the edge; the win validates luck, not the rule. Concrete fix: Require the REPRICING verdict to reference the traded ticker directly (reject entries where the analyst subject ≠ instrument), and add a trailing-stop or scale-out rule (e.g., trail at 40% of max favorable excursion) so a +5.9% peak doesn't decay into a +0.4% exit. |
