Retrospectives

tickermfemaereflection
QCOM S1+0.44%-1.46%

The entry treated a "considering" headline as a repricing event, but speculative policy chatter with no concrete action rarely moves a name durably — QCOM never dropped meaningfully (max favorable move just +0.44%) and drifted against the short for a -1.46% worst drawdown before exiting at a loss. The rationale conflated headline severity with price impact; nothing in the trade confirmed the market was actually repricing. Concrete fix: require confirmation before assigning REPRICING to regulatory news — e.g., only trigger on enacted/announced actions (not "considering/weighing" language), or demand the stock already be down >1% on the headline before shorting; otherwise downgrade the verdict to WATCH.

QCOM S4+5.07%-2.69%

Entry vs. outcome: The short thesis (China export-control headline risk) actually worked — the position was up as much as +5.07% while open — but the rigid "exit at next close" rule let the entire gain evaporate into a -$9 loss when the stock reversed. The failure here isn't the signal, it's the exit mechanics: headline-driven moves on speculative regulatory news ("is considering") tend to mean-revert fast once no concrete action follows.

Concrete improvement: Add a take-profit override to the hold-to-close rule — e.g., exit intraday if unrealized gain exceeds +3%, or trail a stop at 50% of peak unrealized profit. Alternatively, tighten the entry verdict to require confirmed regulatory action rather than "considering" language, since vague headlines produce exactly this spike-and-fade pattern.

📖 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.
