Micron Technology (MU) shares experienced sharp volatility during the week of October 19, 2026, as robust AI-driven memory demand clashed with a broader technology sector selloff. The company’s fiscal Q4 2026 results, released September 30, showed revenue surging to $54.23 billion with adjusted EPS of $33.42—both well above consensus—supported by tight HBM and NAND supply and strong data-center orders. Analyst price targets remained elevated near $1,600–$1,900, reflecting expectations for continued margin expansion into 2027. Offsetting factors included a 6% drop on October 22 tied to market-wide risk aversion and a temporary labor dispute at Micron’s Taiwan facilities, which resolved without prolonged disruption. Traders are now focused on sustained free-cash-flow conversion and upcoming December earnings for signals on pricing power amid capacity additions.
