Nvidia, Meta, and Alphabet joined a policy letter supporting open-weight AI models, a move that could challenge the proprietary moats of closed-model providers like OpenAI and Anthropic.
verdict REPRICING, direction bullish -> long NVDA (regulatory: Nvidia, Meta, and Alphabet joined a policy letter supporting open-weight AI models, a move that could challenge the proprietary moats of closed-model providers like OpenAI and Anthropic.) [closed early: netted out by outranking S1 short NVDA decision 4165]
overnight drift: long NVDA at close, exit next close (regulatory: Nvidia, Meta, and Alphabet joined a policy letter supporting open-weight AI models, a move that could challenge the proprietary moats of closed-model providers like OpenAI and Anthropic.) [skipped at close: outranked — mat 65 long lost to mat 90 long (decision 4368) for S4 NVDA exiting 2026-07-29]
Signal: Right — the bullish call played out, with NVDA rising ~0.35% from entry. Timing: Not pre-empted; entry was only +0.17% above prior close and the last 30m had dipped, so the move came after entry. Exit: Near-optimal capture — the +3.40 P&L (+0.35%) matches the +0.34% best unrealized almost exactly, though credit goes to the mechanical netting against the opposing short (decision 4165), not a deliberate exit rule, and the data can't say whether the move would have extended further. Dominant factor: a correct signal with an incidentally well-timed forced exit on a small move.
📖 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.
