Retrospectives

tickermfemaereflection
MU S1-0.16%-3.96%

The entry called this a "repricing" (structural, bearish regime change) based on macro/regulatory chatter, but the price action was actually a sharp dip that immediately mean-reverted—you sold into a -3.96% unrealized low and got squeezed out for a loss, meaning it was noise/overreaction, not a repricing. Concrete fix: require the REPRICING verdict to be confirmed by sustained price weakness (e.g., price still below entry after N minutes/hours, or a confirming lower high) before firing the trade, rather than acting on the headline/sentiment alone—this would filter out sharp V-shaped reversals like this one.

SMCI S30.00%-3.47%

The entry conflated a sector-wide narrative (HBM export fears, hyperscaler overbuild) with a stock-specific "REPRICING" verdict, but SMCI actually rallied +3% against the short, showing the bearish thesis wasn't confirmed by SMCI's own price action or relative strength versus peers like Dell/Micron before entry. The trade never went favorable (best unrealized 0.00%) and drew down -3.47% before an exit that still lost money, meaning the mechanical rule fired on stale/generic news without a confirming technical trigger (e.g., breakdown below a support level or relative underperformance vs. sector). Fix: require price confirmation (SMCI making a new local low or underperforming a sector ETF/basket by X% intraday) before greenlighting a REPRICING-bearish verdict, not just sentiment/news matching.

MU S4+7.02%-0.28%

The entry rationale correctly identified regulatory/valuation-driven downside momentum, and the trade worked—MU kept sliding overnight, netting +5.6% on the short with only a brief -0.28% dip before running to +7.02% in your favor. The problem is you left ~1.4% of that peak gain on the table by mechanically holding to next-close instead of locking in profit; add a trailing-stop or partial-take-profit rule (e.g., exit at 70-80% of peak unrealized gain) so the strategy captures more of favorable overnight swings instead of riding them back down.

📖 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.
