Advanced Micro Devices (AMD) shares surged over 9% to cross the $1 trillion market capitalization threshold for the first time, joining Nvidia, Broadcom, and Micron in the elite club.
verdict REPRICING, direction bullish -> long AMD (other: Advanced Micro Devices (AMD) shares surged over 9% to cross the $1 trillion market capitalization threshold for the first time, joining Nvidia, Broadcom, and Micron in the elite club.) [skipped: duplicate theme — already holding S1 long AMD exiting 2026-09-22] → close +0.51%
verdict FRESH, direction bullish -> long NVDA (other: Advanced Micro Devices (AMD) shares surged over 9% to cross the $1 trillion market capitalization threshold for the first time, joining Nvidia, Broadcom, and Micron in the elite club.) [skipped: signal conflict — wanted long, conflict-hold — mat 85 ties incumbent S1 short NVDA, incumbent held (strictly higher materiality required to flip)] → close -0.17%
overnight drift: long AMD at close, exit next close (other: Advanced Micro Devices (AMD) shares surged over 9% to cross the $1 trillion market capitalization threshold for the first time, joining Nvidia, Broadcom, and Micron in the elite club.)
Signal: wrong. The predicted overnight drift never materialized — the position was essentially never in profit (best unrealized just +0.04%) and AMD fell ~1.7% from entry to exit. Timing: the cited catalyst (the 9% surge to $1T cap) had already played out before entry — the stock was up only +0.87% intraday at decision time, so the trade was buying after the news-driven move, though the data here can't confirm exactly when the surge occurred relative to entry. Exit: reasonable given what was available — the mechanical next-close exit at -1.73% landed between the best (+0.04%) and worst (-2.53%) marks, and no exit rule could have captured meaningful profit since none existed. Dominant factor: signal failure — entering long on a stale, already-priced-in catalyst.
📖 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.
