🧭 Decisions
| strategy | ticker | action | side | rationale |
|---|---|---|---|---|
| S1 | META | ● enter | ▼ short | verdict FRESH, direction bearish -> sell META (regulatory: Chinese regulators are considering strict bans on Western acquisitions of Chinese AI firms and restricting overseas foundries like TSMC and Qualcomm from manufacturing advanced chips for Chinese designs.) |
| S2 | - | ○ skip | — | no counterparty in universe |
| S3 | NVDA | ○ skip | — | direction unclear for NVDA → close +0.65% |
| S4 | META | ● enter | ▼ short | overnight drift: sell META at close, exit next close (regulatory: Chinese regulators are considering strict bans on Western acquisitions of Chinese AI firms and restricting overseas foundries like TSMC and Qualcomm from manufacturing advanced chips for Chinese designs.) |

Retrospectives
| ticker | mfe | mae | reflection |
|---|---|---|---|
| META S1 | +0.61% | -0.49% | Rationale vs. outcome: The catalyst is about Chinese regulators, TSMC, and Qualcomm — META has no meaningful direct exposure to any of that, so the bearish META thesis was a stretch that happened to scrape out +0.38%. The narrow excursion range (+0.61%/-0.49%) says this was noise the whole time, not a working thesis; the win is luck, not validation. Improvement: Add a relevance gate to the entry rule: a FRESH verdict should only trigger a trade if the catalyst explicitly names the ticker or a direct revenue/supply-chain dependency (e.g., this headline could justify shorting QCOM or TSM, not META). Sector-adjacent vibes shouldn't clear the bar. |
| META S4 | +3.23% | -2.04% | Rationale vs. outcome: The entry cited China chip/AI regulatory news as the catalyst, but META has minimal direct exposure to Chinese acquisitions or TSMC-for-Chinese-designs restrictions — this reads like a headline-matching false positive that happened to work (+2.6%). The -2.04% adverse excursion on an overnight hold shows the position was essentially a coin flip that landed well, so don't let the P&L validate the logic. Improvement: Add a catalyst-relevance gate to the entry rule: only trade a ticker if the cited news names the company or a direct supplier/customer/revenue segment (e.g., META qualifies on ad-spend or Reality Labs supply-chain news, not Chinese foundry policy). Alternatively, require the rationale-to-ticker link to score above a threshold before the overnight-drift signal is actionable — right now the verdict fires on macro noise. |
📖 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.
