Micron Technology had one of those runs that makes even seasoned investors do a double take. Shares surged over 250% year-to-date by mid-2026, riding a wave of AI-fueled demand for high-bandwidth memory chips.
After reporting strong Q3 fiscal results on June 24-25, Micron’s stock initially popped, then proceeded to fall more than 22% from its post-earnings highs by early July, dipping below pre-report levels while remaining significantly higher compared to the beginning of the year.
The AI memory boom meets gravity
Micron’s high-bandwidth memory production is completely sold out through the end of 2026, driven almost entirely by demand from AI accelerators.
The selloff started before earnings even landed. On June 23, shares dropped approximately 13% in a single session, dragged down by weakness in South Korean memory chip stocks that spooked the broader sector.
