Micron Technology stock closed at USD 923.97 on Nasdaq on September 14, 2026, down 5.2 percent. The move came amid a wider chip selloff that left the Nasdaq Composite lower on the same session.

September 14, 2026 in numbers

According to Reuters, AI warnings pressured chipmakers on September 14, 2026, and Micron Technology Inc. (ISIN US5951121038) dropped over 5 percent. A Yahoo Finance market page showed the stock at USD 923.97 in the latest close session, with a 5.26 percent decline. Reuters also said the Nasdaq Composite and the S&P 500 opened lower on the same market day, with chip stocks under pressure.

On the same session, the stock traded between USD 918.70 and USD 976.00, and the close sat near the lower end of that band. Yahoo Finance and Reuters both tied the move to broader weakness in AI-related names, while the Nasdaq Composite finished lower on the day.

Results due September 30, 2026

Micron's fiscal fourth-quarter results are scheduled for September 30, 2026, and that date remains the key company event on the calendar. Reuters also reported that Asian chip shares were mixed on September 15, 2026, as caution around AI names carried into the new session, which keeps the sector backdrop relevant for Micron today.
