On August 19, Entegris fell 5.65% in regular trading, trading at $144.05/share, with turnover of $43.80 million. The stock retreated sharply as rising long-term U.S. Treasury yields pressured high-growth technology stock valuations broadly.

On the news front, surging long-end bond yields triggered a rotation out of AI momentum names into defensive assets, sending the Philadelphia Semiconductor Index down nearly 5%. The semiconductor equipment sector declined in unison, with AXT Inc down 10.44%, Lam Research down 4.98%, Applied Materials down 3.88%, KLA Corporation down 3.86%, and ASML Holding down 2.34%, amplifying selling pressure on Entegris.

The stock had previously rallied over 7% on August 12-13 after Deutsche Bank upgraded it to buy with a $200 price target, citing an upcoming capital expenditure cycle in chip equipment. Following significant short-term cumulative gains, the macro-driven liquidity disruption combined with profit-taking further magnified the pullback.
