Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| MU S1 | +0.03% | -0.26% | Signal: The predicted bullish move never materialized while the trade was open — price stayed essentially flat (range +0.03% to -0.26%), so the data can't confirm the direction was right, only that it didn't pay off in the holding window. Timing: No evidence the move had already happened; price was slightly down (-0.69% from prev close) at entry, so this wasn't a chase — the catalyst simply produced no follow-through. Exit: The exit was fine — -0.03 USD on a max unrealized range of roughly +0.03%/-0.26% means the exit captured close to the best available and avoided the worst. Dominant factor: signal — the news catalyst generated no tradeable move during the trade's life; timing and exit were non-issues. |
| MU S4 | +1.97% | -1.89% | Signal: Wrong at the trade's horizon — the overnight-drift thesis called for upside, but MU closed lower and the trade lost -1.07%. The stock did trade up to +1.97% unrealized while open, so the direction was briefly right intraday, just not at the fixed exit. Timing: The data doesn't show the move had already happened — price was only -0.69% off the prior close at decision time, which isn't evidence of a spent rally. Exit: This is the dominant factor. The mechanical next-close exit gave back the entire +1.97% peak and settled near the worst unrealized (-1.89%), capturing close to the bottom of the range that was available. The signal produced a tradeable up-move; the fixed exit rule realized a loss instead. |
📖 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.
