Alphabet raised its 2026 capital expenditure guidance to $195B-$205B, driving a surge in Micron shares due to increased demand for high-bandwidth memory chips.
verdict FRESH, direction bullish -> buy MU (guidance: Alphabet raised its 2026 capital expenditure guidance to $195B-$205B, driving a surge in Micron shares due to increased demand for high-bandwidth memory chips.)
overnight drift: buy MU at close, exit next close (guidance: Alphabet raised its 2026 capital expenditure guidance to $195B-$205B, driving a surge in Micron shares due to increased demand for high-bandwidth memory chips.) [skipped at close: outranked — mat 65 buy lost to mat 85 buy (decision 2308) for S4 MU exiting 2026-07-24]
The rationale was second-hand momentum: Alphabet's capex raise had already "driven a surge" in MU by the time of entry, so the trade bought the top of a move that was priced in, and the stock mean-reverted for a -1.5% loss. The FRESH verdict is doing no work here — news about a different company's spending, plus an already-realized rally, should not qualify as fresh actionable information for MU. Concrete fix: add a price-extension filter to the FRESH verdict — skip (or downgrade to STALE) any entry where the target has already moved more than ~2% on the headline, or require a pullback to VWAP before buying sympathy plays.

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.
