Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| GOOGL S1 | +0.53% | -0.18% | Retro note: The bearish call was built on a genuinely mixed catalyst — a product delay (negative) paired with cost-reducing launches (arguably positive) — and the market treated it as such: the stock barely moved (-0.46%), with max favorable excursion of only 0.53%. The trade "won" by noise, not thesis; a +$3.24 scratch on a FRESH verdict suggests the signal was too weak to deserve that label. Improvement: require unambiguous directional catalysts for FRESH (e.g., downgrade mixed positive/negative headlines to STALE or NO-TRADE), or add a minimum expected-move filter so entries need a plausible path to >1% before committing capital. |
| MSFT S3 | +0.05% | -0.45% | Entry vs. outcome: The rationale is about Alphabet (new Gemini models, delayed flagship), yet the trade bought MSFT — a second-order "competitor benefits" inference at best, and the market never validated it (max favorable excursion of just +0.05% vs. -0.45% adverse, closing at -2.76 USD). A "FRESH" verdict on news about a different company is a ticker-mapping failure, not a fresh signal for MSFT. Improvement: Add a hard entity-match gate to the entry rule: the traded ticker must be the primary subject of the catalyst, or cross-ticker trades must require an explicit, scored spillover thesis (e.g., relevance ≥ 0.8) rather than inheriting the FRESH verdict from another company's news. |
📖 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.
