Amazon has completed a $50 billion investment in OpenAI through three staged payments, solidifying their strategic partnership in cloud computing and AI.
verdict FRESH, direction bearish -> short MSFT (partnership: Amazon has completed a $50 billion investment in OpenAI through three staged payments, solidifying their strategic partnership in cloud computing and AI.)
Signal: Directionally correct but barely — MSFT drifted down slightly after entry, and the trade closed +$1.46. Timing: MSFT was already down 0.69% from prior close at decision time, and the post-entry range was tiny (+0.18%/-0.33%), so most of any news-driven move had likely already occurred; the data can't confirm exactly when the news broke relative to that decline. Exit: The exit was fine — it captured roughly +0.15% of a +0.18% max, near the best available.
Dominant factor: timing. The "FRESH" verdict looks stale — there was almost nothing left to capture after entry, and the small profit reflects noise-level drift, not the thesis playing out.

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.
