Retrospectives

tickermfemaereflection
QCOM S1+0.43%-0.71%

Timing is the dominant factor. The entry chased a move already underway (+1.31% from prev close, +0.43% in the prior 30 minutes), buying at 176.29 against a 174.09 prior close, so much of the immediate repricing was likely captured before the fill. Signal: during the holding window the bullish direction never confirmed — the stock topped out at +0.43% unrealized and dipped to -0.71%, so the data here shows chop, not a validated or invalidated thesis (whether the news repriced QCOM later is not settled by this window). Exit: the -0.60 USD result (-0.07%) landed near the middle of a tight ±0.5–0.7% range, meaning the exit gave up little because there was little available to capture; the problem was paying up at entry, not the exit.

QCOM S4+3.29%-3.73%

Signal: Right — QCOM closed higher than entry, consistent with the partnership thesis. Timing: Partly chased — entry at 176.20 was already +1.21% above the 174.09 prev close, so a chunk of the news pop was absorbed before fill. Exit: This is the dominant factor — the trade captured +0.57% (+$5) against a best unrealized of +3.29% (~+$29 on this position), so the mechanical next-close exit gave back roughly five-sixths of the available gain, though it also sat through a -3.73% drawdown that the fixed hold happened to survive. The data doesn't show when the peak/trough occurred intraday, so whether an earlier exit was practically reachable isn't settled here.

📖 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.
