# U.S. stock market midday update: MKS down 13%, not mentioned by Citigroup and Wells Fargo, semiconductor sector bull market logic remains strong

**U.S. Stock Market Midday Update**

MKS fell by 13.00%. Based on recent news,

1.  On June 30, MarketBeat pointed out that MKS was not included in the list of five stocks recommended by top analysts. Although MKS currently has a moderate buy rating among analysts, top analysts believe that the other five stocks have more investment value, which may lead to a decline in investor confidence and a drop in stock price.

2.  On June 30, Wells Fargo released a research report indicating that the long-term bull market logic for the semiconductor equipment sector is becoming increasingly robust, with expectations for significant growth in the global wafer fabrication equipment market. However, MKS was not specifically mentioned in the report, which may affect its market performance.

3.  On June 30, Citigroup raised the target prices for Applied Materials, Lam Research, and KLA, showing strong confidence in these companies, but did not mention MKS, which may lead to lowered expectations for MKS and impact its stock price. The long-term bull market logic for the semiconductor equipment sector remains strong, with expectations for market size growth.
