Retrospectives

ticker	mfe	mae	reflection
AMZN S1	+2.03%	+0.31%	Signal: Right — the bearish call played out; the trade was never underwater (worst unrealized +0.31%). Timing: Fine — price was up +0.69% from prior close at decision time, so the anticipated decline had not already occurred; the entry caught the move rather than chasing it. Exit: The weak point — the trade peaked at +2.03% unrealized but closed at roughly +0.77% (+$6.06), giving back about two-thirds of the available gain. Dominant factor: exit execution, not signal or timing.

S2 counterparty — trades the inferred counterparty ticker (weakest signal, LLM-inferred sympathy); exits at the same day's close.

S4 overnight — holds the primary ticker from today's close to the NEXT day's close.
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.
