Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| MU S4 | +4.58% | -6.43% | Signal: Partially right — MU rose as much as +4.58% while the trade was open, so the predicted upward drift did materialize intraday, but it fully reversed by the mechanical next-close exit. Timing: The stock was already +1.74% off the prior close at decision time, so some of the move preceded entry; however, the entry fill (915.05) sits well below the quoted prior close (959.48), a discrepancy this data doesn't explain, so entry timing can't be fully assessed. Exit (dominant factor): The fixed next-close exit is the blunt failure here — the trade held through a +4.58% peak and closed at -2.56%, much nearer the -6.43% worst than the best available, converting a winning signal into a loss. |
📖 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.
