On September 14, Micron Technology fell 4.53% in pre-market trading, trading at $928.49/share, with turnover of $83.66 million. The decline came amid a broad semiconductor selloff triggered by multiple macro headwinds converging simultaneously.

On the news front, three major AI giants issued a joint call to significantly slow AI model training and development, dealing a direct blow to AI hardware demand expectations. Meanwhile, U.S. August PPI came in above expectations at 5.4% year-over-year, pushing the probability of a Fed rate hike at the September 15-16 meeting to approximately 71.3%, with traders fully pricing in an October hike. Surging oil prices — with Brent crude breaking above $100 — further intensified risk-off sentiment across growth sectors.

The semiconductor sector saw widespread losses, with the Philadelphia Semiconductor Index dropping sharply. NVIDIA fell 2.08%, AMD declined 4.77%, Intel dropped 5.54%, Broadcom slid 2.99%, and TSMC lost 3.06%. Storage peers SK Hynix and SanDisk also fell over 5% in dark-pool trading. Micron's options market had been flashing bearish signals ahead of the move, including a $26.93 million deep-in-the-money put and a dual-sell call spread, reflecting large-fund caution ahead of its September 30 earnings report.
