Popular sector aspects

1. Semiconductor equipment and targets: Zhengfan Technology rose and stopped at 20CM, China and Micro rose 12.67%, Tuojing Technology rose 12.14%, stocks such as Research New Materials, Fujing Technology, Bojie shares, and Jinhaitong (2 connected boards), and Jiang Feng Electronics rose 11.16%. According to the news, Samsung Electric has uniformly raised MLCC shipping prices by 30% since August 1. In addition, SEMI predicts that global semiconductor equipment sales will reach US$165.9 billion in 2026, up 23.2% year on year. Domestic substitution and price increases resonate with expectations.

2. Glass fiber and electronic cloth: Sinoma Technology and Honghe Technology rose and stopped, international composites rose 14.04%, China Jushi closed up 8.54%, and Shandong glass fiber rose 7.28%. The catalyst was that the average price of electronic cloth rose 17%-18% month-on-month in August, with a cumulative increase of 118%-165% during the year (Citi quoted SCI99 data).
