Micron shares traded in the low $900s through the week of October 12 after a sharp mid-month pullback, positioning the sub-$940 close as the dominant market-implied outcome at 80%. Strong fiscal Q4 2026 results, including $54.2 billion revenue and robust HBM demand tied to AI, initially supported prices near $1,000 early in the period, but broader semiconductor weakness—driven by rising Treasury yields, AI financing concerns, and competitive pressure from Chinese memory makers—pushed the stock down roughly 12% from prior levels. Recent analyst notes highlight long-term supply tightness and customer agreements as supportive, yet short-term sentiment remains cautious ahead of further macro data.
