On September 14, Qnity Electronics Inc fell 6.57% in regular trading, trading at $118.15 per share, with turnover of $61.638 million.

The decline came amid a sweeping selloff across the semiconductor sector driven by multiple headwinds. The U.S. 10-year Treasury yield surged to 5%, a three-year high, as markets priced in a near-90% probability of a 25-basis-point rate hike at the upcoming Fed meeting on September 17. Separately, Anthropic CEO Dario Amodei published an article calling on the industry to slow frontier AI model development, amplifying investor concerns over AI-driven demand sustainability for chip materials.

Escalating U.S.-China trade tensions and tightened semiconductor export controls further compounded systemic pressure on the equipment and materials supply chain. Within the Semiconductor Equipment sector, ASML Holding fell 6.37%, Applied Materials fell 6.35%, Lam Research fell 7.57%, KLA Corporation fell 6.20%, and Teradyne fell 11.81%.
