overnight drift: long AMD at close, exit next close (m&a: AMD's World Labs Deal Signals Shift to Physical AI) [skipped at close: outranked — mat 89 long lost to mat 90 long (decision 23924) for S4 AMD exiting 2026-09-30]
Signal: right. The bearish call played out — NVDA fell 1.37% from entry (230.54 → 227.39), with the trade never more than 0.38% underwater. Timing: not premature/late. At decision time the stock was up 0.71% on the day and still drifting higher, and the fill came in near that level, so the down-move had not yet occurred and the short was placed close to the local high. Exit: near-optimal. The realized +1.37% is essentially the full +1.40% best unrealized, so almost nothing was left on the table. Dominant factor: a correct directional signal that was executed and closed cleanly; whether the M&A-article thesis was actually the cause of the drop isn't determinable from this data.

Verdicts are decided top-to-bottom, first match wins; REPRICING is also the fallback when nothing else matches (2026-08-08 #220).
UNKNOWN — a needed price input (move since close or move in the last 30m) is missing.
PRICED — |move since previous close| ≥ 2.0%: already reflected in price.
REPRICING — |move in the last 30m| ≥ 0.5%: the tape is actively moving on it. Also covers a quieter move — |move since previous close| in [1.0, 2.0) with a quiet last-30m tape: still developing, not yet priced.
FRESH — |move since previous close| < 1.0%: a genuinely new move.
materiality — how market-moving the story was judged, 0-100 — alerts require materiality ≥ 70.
