Amazon raised its 2026 capital expenditure guidance to $220 billion but warned that AI capacity constraints will persist through 2027 due to long infrastructure lead times.
verdict FRESH, direction bullish -> long AMZN (guidance: Amazon raised its 2026 capital expenditure guidance to $220 billion but warned that AI capacity constraints will persist through 2027 due to long infrastructure lead times.) [skipped: signal conflict — wanted long, conflict-hold — mat 65 ties incumbent S1 short AMZN, incumbent held (strictly higher materiality required to flip)] → close +0.30%
overnight drift: long AMZN at close, exit next close (guidance: Amazon raised its 2026 capital expenditure guidance to $220 billion but warned that AI capacity constraints will persist through 2027 due to long infrastructure lead times.)
Signal: Wrong over the traded horizon. The rationale bet on upward drift from raised capex guidance, but the close-to-close move was -1.47% (249.75 → 246.08); the stock did trade up to +3.61% at some point overnight/intraday, but ended well below entry, so the news read as net negative by the exit close. Timing: Not the problem — pre-entry drift was flat (-0.16% since prior close, +0.32% in the last 30m), so no move had been front-run. Exit: The fixed next-close exit captured none of the +3.61% peak (~+$36 on 4 shares) and landed near the -2.32% trough, giving back roughly 5 points of range; the data doesn't show when the peak occurred, so I can't say whether any earlier exit was realistically reachable.
Dominant factor: signal failure — the predicted direction did not hold over the strategy's own one-day window, and the mechanical exit realized the reversal rather than the transient rally.
📖 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.
