📈 Trades
| strategy | ticker | side | qty | entry | exit | P&L $ | status |

Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| GOOGL S1 | +0.63% | -0.40% | Signal: Marginally right — the bullish call did see price move up to +0.63% unrealized, so direction wasn't wrong, though the DDR4-shortage rationale's link to GOOGL upside can't be validated from this data. Timing: The fill at 342.26 was ~1.5% above prev close (337.12), while the decision-time context showed only +0.26% — so a meaningful chunk of the move occurred between decision and entry, eroding the edge. Exit: This is the dominant factor: the trade captured +$0.12 (+0.02%) against +0.63% of favorable movement available — roughly 3% of the peak unrealized gain — so the exit gave back nearly everything the (weak) signal delivered. |
📖 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.
