Microsoft and NVIDIA confirmed a joint October 7 event to showcase local AI innovations, including the Surface Laptop Ultra powered by the new NVIDIA RTX Spark processor.
verdict REPRICING, direction bullish -> long MSFT (product: Microsoft and NVIDIA confirmed a joint October 7 event to showcase local AI innovations, including the Surface Laptop Ultra powered by the new NVIDIA RTX Spark processor.) [skipped: signal conflict — wanted long, conflict-hold — mat 65 ties incumbent S1 short MSFT, incumbent held (strictly higher materiality required to flip)] → close +0.42%
overnight drift: long MSFT at close, exit next close (product: Microsoft and NVIDIA confirmed a joint October 7 event to showcase local AI innovations, including the Surface Laptop Ultra powered by the new NVIDIA RTX Spark processor.)
Signal/timing failure, not exit. The predicted upward drift never materialized — MSFT was already up ~1.1%+ on the news by entry (490.30 → 497.94 fill), so the catalyst was plausibly priced in, and the position never got more than +0.29% ahead before rolling over. The exit at -0.91% (-$9.08) was actually well above the -4.50% worst unrealized, so the mechanical next-close exit captured close to the best of a bad situation. The data can't fully separate "wrong direction" from "right thesis, already spent" — but either way, the dominant factor is entering after the news-driven move, leaving no drift left to harvest.
📖 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.
