Retrospectives

tickermfemaereflection
NVDA S1+1.46%-0.91%

Comparison: The entry rationale was momentum-chasing on already-realized news — NVDA had already declined sharply when the trade fired, so the "repricing" was mostly priced in. The outcome confirms this: +0.59% captured on a trade that never moved more than +1.46% in your favor, meaning the thesis had almost no edge left at entry. A +$4.84 scalp on a "sharp sector-wide repricing" verdict is a rationale/outcome mismatch — either the verdict was overstated or the entry was too late.

Improvement: Add a staleness/extension filter to the REPRICING verdict: skip entry if the instrument has already moved more than ~1.5–2% in the signal direction over the prior session, or require the entry within N hours of the catalyst. Alternatively, demote late-arriving REPRICING signals to a lower-conviction tier with reduced size, since you're selling into a move that's largely done.

AMD S3+1.47%-3.17%

The entry chased an already-realized selloff — "declined sharply" means the repricing had largely happened by entry, so shorting AMD at 490 was momentum-following into a bounce, and the trade never got more than +1.47% before reversing to -3.17% and stopping out at a loss. The rationale also leaned on sector-wide sentiment (NVDA, MU, TSMC) rather than anything AMD-specific, making the direction call weak. Concrete fix: require the REPRICING verdict to trigger only if the catalyst is fresh (e.g., within the last session) AND the stock hasn't already moved more than ~2% in the verdict's direction — otherwise downgrade to no-trade or demand a pullback entry.

📖 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 ≥ 60.
