Why is Micron Technology, Inc. (MU) stock moving?

Micron Technology (MU) experienced severe selling pressure on Nov 5, dropping 17.46% to close at $656.39 on extraordinary capitulatory volume of 77.87 million shares. The abrupt selloff was triggered by headlines confirming the suspension of Micron's $4.5B Taoyuan, Taiwan fab expansion due to a union wage dispute, alongside sector-wide de-risking in semiconductor and AI infrastructure names following U.S. midterm election results. Despite headline disruptions, Micron's fundamental engine remains exceptionally strong: Q4 fiscal revenue climbed 379% year-over-year to $54.23B with 87% gross margin, backed by over 75% of 2027 memory capacity pre-committed and guidance projecting $61.5B in Q1 revenue. With shares rebounding over 4% in after-hours trading and valuation compressing under 10x trailing EPS and roughly 4-6x forward earnings, the market appears to be transitioning from panic liquidation toward a major valuation floor.
