Retrospectives

tickermfemaereflection
AAPL S1+0.96%-0.40%

The entry treated "politicians calling for" a ban as a FRESH bearish catalyst, but rhetoric without enacted policy is low-materiality noise for a mega-cap like AAPL — and the price action confirmed it, chopping ±1% and closing essentially flat. Worse, the short was up +0.96% unrealized and still exited at a loss, so the trade management gave back the entire move. Concrete fix: require regulatory headlines to involve enacted or imminently scheduled action (not calls/proposals) to earn a FRESH verdict, and add a take-profit or trailing stop that locks in gains once unrealized PnL exceeds ~0.5%.

AAPL S4+2.22%+0.01%

Entry vs. outcome: The regulatory-headline short worked — the thesis (negative China supply-chain news drives overnight weakness) played out cleanly, with the position never going underwater (worst drawdown +0.01%) and closing +1.56%. However, the rigid "exit next close" rule gave back nearly a third of the move, since peak unrealized gain was +2.22%.

Improvement: Replace the fixed next-close exit with a trailing stop (e.g., exit if price retraces 0.5% from the intraday extreme) or a profit target at ~2%, so winners that hit their thesis early don't decay while waiting for an arbitrary clock-based exit. One caveat for the retro: a single 3-share trade proves nothing — don't tune thresholds until this setup has a sample size.

📖 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.
