Meta announced a $9 billion investment in a 1 GW AI data center campus in Alberta, Canada, and is expanding its Louisiana Hyperion campus into a 5 GW AI supercluster.
verdict FRESH, direction bullish -> long META (other: Meta announced a $9 billion investment in a 1 GW AI data center campus in Alberta, Canada, and is expanding its Louisiana Hyperion campus into a 5 GW AI supercluster.) [skipped: signal conflict — wanted long, conflict-hold — mat 65 ties incumbent S1 short META, incumbent held (strictly higher materiality required to flip)] → close -0.16%
overnight drift: long META at close, exit next close (other: Meta announced a $9 billion investment in a 1 GW AI data center campus in Alberta, Canada, and is expanding its Louisiana Hyperion campus into a 5 GW AI supercluster.)
Signal: Directionally right, but barely — the long finished +0.12%, which is weak confirmation of the news-driven drift thesis. Timing: Not a pre-run entry; the stock was flat-to-down at decision time (-0.17% from prior close), so the move hadn't already happened. Exit: This is the dominant factor — the fixed next-close exit captured only +0.12% of a +2.52% best unrealized gain while sitting through a -5.62% drawdown, meaning the mechanical hold both left most of the available upside on the table and took on risk far out of proportion to the realized reward.
📖 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.
