Retrospectives

ticker	mfe	mae	reflection
AMZN S1	+1.12%	+0.20%	Signal: Right — the bullish call played out; price rose from entry and never traded below it (worst unrealized was still +0.20%). Timing: Not late — price was down 0.83% from prior close and drifting lower at entry, so the entry caught the move before it happened rather than chasing it. Exit: The dominant weakness — the trade realized +0.60% (+$4.47) against a best unrealized of +1.12%, so the exit gave back roughly half the available gain. Whether that peak was fleeting or held near exit isn't shown here, so I can't say how capturable it actually was.

📖 Glossary

S1 primary — trades the alert's primary ticker in the direction the article itself indicates; exits at the same day's close.
S2 counterparty — trades the inferred counterparty ticker (weakest signal, LLM-inferred sympathy); exits at the same day's close.
S3 peer — trades an inferred peer ticker (also 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.
