Micron Technology Shares Drop Amid Semiconductor Sector Decline
Micron Technology (NASDAQ:MU) shares fell by 5.2% in pre-market trading on September 14, 2026, as semiconductor stocks declined due to concerns over the pace of AI development and broader market uncertainties. The stock was down about 26% from its 52-week high of $1,255. Investors are also awaiting Micron's fiscal fourth-quarter earnings report on September 30. Broader chip sector weakness followed calls by tech executives for slower AI growth, which could impact spending on semiconductor and data-center infrastructure. The Trump administration is considering new tariffs that may extend to downstream products like servers and laptops, raising concerns about increased costs in the AI industry. Micron also faces a patent lawsuit from Netlist involving its DDR5 memory products. Meanwhile, higher Treasury yields and oil prices contributed to broader market declines, with both the Nasdaq and S&P 500 trading lower.
