| TSM S1 | +0.76% | -1.62% | The entry thesis was a slow-moving structural story (packaging stays in Taiwan through 2028) — that's not a repricing catalyst, it's already-known context with no near-term trigger, and the trade predictably drifted to -1.4% with barely any favorable excursion (+0.76% max). The verdict "REPRICING" was mislabeled: nothing in the rationale identifies new information the market hadn't digested. Concrete fix: require REPRICING verdicts to cite a specific surprise vs. consensus (new number, guidance change, or dated event within ~2 weeks) or downgrade them to no-trade; multi-year supply-chain narratives should fail that filter automatically. |
| TSM S4 | +2.50% | -3.17% | Signal: Wrong over the intended horizon — the overnight-drift thesis predicts a positive close-to-close return, and the realized move was -0.82% (402.09 → 398.81). The rationale's supply-chain narrative is a multi-year structural point with no clear link to a one-day drift bet either way. Timing: The stock was already down ~1.9% from prior close at decision time, but the data here doesn't tell us whether that dip helps or hurts a drift signal, so timing can't be settled from what's given. Exit: The position saw +2.50% unrealized at its best, so roughly +$20 was available versus the -$6.56 realized — the fixed next-close exit gave all of it back. Bluntly, the dominant factor is the signal failing over its stated holding period; the exit "left money on the table" only relative to an intraday peak the strategy never intended to capture. |
