Micron shares have surged to $895.88, driven by extreme AI enthusiasm, but the trailing P/E of roughly 118x (FY2025 diluted EPS $7.59) and a free cash flow yield of just 0.3% due to massive $15.9B capex signal a euphoric valuation divorced from fundamentals. Aggressive insider selling of over $307 million net in 24 months and an RSI of 75 indicate a blow-off top. We recommend taking profits before mean reversion resumes the memory cycle's historic pattern of booms and busts.
AI demand acceleration
Sustained exponential growth in AI memory demand could push DRAM/NAND pricing and volumes far above current estimates, justifying an even higher multiple.
Prolonged supply tightness
Supply constraints may persist for years, enabling Micron to maintain exceptional margins and earn out its valuation if earnings catch up.
Retail and passive momentum
The stock could continue rising purely on sentiment and ETF inflows, overriding fundamental signals in the short to medium term.
Government/strategic intervention
Political support or subsidies (e.g., CHIPS Act funding) could de-risk capex and improve FCF, altering the risk profile.
