🚨 Alert #5533 Fri Sep-25 18:50:37

Signal: Wrong within the holding window — the bearish thesis never materialized; TSM drifted slightly up and the trade exited at a loss. Whether the macro thesis was wrong or just slower than the holding period, this data can't settle.

Timing: Not stale — price was flat at entry (+0.01% since prior close), so the trade wasn't chasing an already-completed move.

Exit: Poor relative to what was available: the position saw +0.17% unrealized favorable but exited near the worst (-0.18%, actual -0.05%/-$0.44). That said, the entire range was under ±0.2%, so the dominant factor is the signal — the predicted move simply didn't happen, and everything else is noise-scale.

Signal: Wrong at the horizon that mattered — the short thesis called for a down drift, but TSM closed +0.43% above entry (451.04 → 452.96), and the path spent as much as 6.72% against the position versus only 1.71% in favor, so the day was net bearish for a short. Timing: The entry wasn't late — price was flat versus the prior close (+0.01%, last 30m −0.04%), so no move had been front-run before the fill; the problem is that the predicted move never materialized, not that it was already priced. Exit: The mechanical next-close exit captured none of the +1.71% that was briefly available but also sidestepped the −6.72% worst case, ending at a modest −$3.84 — the exit rule was neither the culprit nor a rescue here.

Dominant factor is signal: a vague regulatory headline (Chinese mobilization law) was mapped to a one-day TSM short and the direction simply didn't hold. Whether the headline had any causal link to TSM's intraday swings can't be determined from this data.
