Amazon Web Services confirmed permanent data loss and significant infrastructure impairment in its Middle East regions following Iranian drone strikes that overwhelmed backup systems.
verdict FRESH, direction bearish -> short AMZN (other: Amazon Web Services confirmed permanent data loss and significant infrastructure impairment in its Middle East regions following Iranian drone strikes that overwhelmed backup systems.)
overnight drift: short AMZN at close, exit next close (other: Amazon Web Services confirmed permanent data loss and significant infrastructure impairment in its Middle East regions following Iranian drone strikes that overwhelmed backup systems.) [skipped at close: outranked — mat 85 short lost to mat 85 long (decision 19996) for S4 AMZN exiting 2026-09-21]
Signal (dominant factor): The bearish call was simply wrong — despite catastrophic-sounding news, AMZN drifted up while the trade was open (max favorable only +0.35% vs. -1.00% adverse), so the market never validated the thesis. Timing: Entry wasn't chasing a move that had already happened (price was only +0.25% off prior close with a flat last 30 minutes), so entry timing isn't the issue. Exit: The -0.54% realized loss sits between the +0.35% best and -1.00% worst, so the exit gave back nothing egregious and avoided the full drawdown — the loss came from a bad signal, not bad execution. Note: the data here can't confirm whether the underlying news event was real or accurately characterized, only that the market didn't trade as if it mattered.
📖 Glossary

S2 counterparty — trades the inferred counterparty ticker (weakest signal, 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.
