Signal: Nominally right — exit was above entry — but the move was only +0.14%, and the stock traded as far down (-0.44%) as it did up (+0.41%) while open, so the bullish call isn't meaningfully confirmed; the M&A catalyst produced no directional thrust discernible from this data. Timing: Not stale — price was +0.07% vs prev close and flat over the prior 30m at decision, and the fill at 333.01 was only +0.08% above the 332.75 close, so the trade didn't chase a move that had already occurred. Exit: Captured about a third of the best available (+0.135% realized vs +0.41% peak), which is acceptable given the symmetric noise; the dominant factor is simply a non-event catalyst — the stock barely moved in either direction, and the +1.35 USD is noise-sized profit rather than a captured signal.
📖 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.
