Micron shares fell as reports emerged that Apple is testing memory chips from Chinese rival CXMT, raising concerns about increased competition and pricing pressure in the DRAM market.
verdict FRESH, direction bearish -> short MU (other: Micron shares fell as reports emerged that Apple is testing memory chips from Chinese rival CXMT, raising concerns about increased competition and pricing pressure in the DRAM market.) [skipped: duplicate theme — already holding S1 short MU exiting 2026-08-03] → close +1.23%
overnight drift: short MU at close, exit next close (other: Micron shares fell as reports emerged that Apple is testing memory chips from Chinese rival CXMT, raising concerns about increased competition and pricing pressure in the DRAM market.)
Signal was wrong: the short bet on continued downside from the Apple/CXMT news failed outright — MU rose ~7.5% from entry to exit. Timing wasn't the issue in the "move already happened" sense (price at decision was flat vs. prior close), though the fill at 832.09 vs. prev close 823.03 meant the short started ~1% worse than the decision-time context suggested. The exit was near the worst available (-7.5% realized vs. -8.30% worst / +0.79% best), but with less than 1% of favorable movement ever on offer, no exit could have salvaged this — the dominant factor is a bad directional signal.
📖 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.

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.
