Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| AMZN S4 | +1.99% | -3.49% | Signal: right. The long call on the AWS earnings beat worked — the stock rose +1.67% from entry to exit. Timing: partially late. The fill at 254.31 was already ~1.2% above the prior close of 251.19, so a chunk of the post-earnings pop was captured by others before entry (the data doesn't show how much more the stock had gapped between decision and fill, only that the fill was well above the known +0.63%). Exit: near-optimal. The +1.67% realized captured almost all of the +1.99% best unrealized, and the trade survived a substantial -3.49% drawdown along the way. Dominant factor: a correct directional signal with a well-timed exit; the drawdown shows the position was exposed to meaningful adverse volatility, but the scheduled exit happened to land near the high. |
📖 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.
