Micron (MU) shares closed September 28 near $1,054 amid a broad risk-off move in high-beta semiconductors, pressured by rising Treasury yields and oil prices ahead of the company’s fiscal Q4 earnings release after the close on September 30. Traders are focused on consensus expectations for revenue near $51 billion—more than triple the year-ago figure—and adjusted EPS around $31.50, reflecting sustained AI-driven demand for high-bandwidth memory, tight supply, and gross margins approaching 86%. The stock’s 2026 advance of roughly 270% and 52-week range up to $1,255 underscore how momentum hinges on whether results and guidance extend the memory-cycle upswing into 2027, with any shortfall likely amplifying volatility through the October 2 week-end close.
