Signal: Wrong — the bearish call on AMZN never materialized; the stock went from 253.54 to 256.31 against the short, and the best unrealized was only -0.19% (never positive). The article (Paramount/WBD merger) is also a weak, indirect driver for Amazon, which makes the premise itself questionable, though this data can't prove why price rose.
Timing: Not the dominant issue — AMZN was up only +0.91% on the day with a +0.21% last-30m drift at decision time, so the short wasn't chasing an exhausted move; the entry at 253.54 vs. known ~253.5 context shows no notable fill slippage.
Exit: Decent given a losing trade — closed at roughly -1.09% versus a worst unrealized of -1.21%, so the exit was near the trough rather than letting it run further, but there was nothing available to capture upside-wise. Dominant factor: direction was simply wrong (signal failure).
📖 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.
