"Hard tech" sees buybacks and increases in holdings; listed companies demonstrate confidence in development through real gold and silver buybacks and increases in holdings.

Title context: Text: On November 6 in the A-share market, domestic semiconductor companies such as Hua Hong Semiconductor moved higher against the trend, with some leading companies rebounding quickly after opening sharply lower. Overnight, the U.S. semiconductor sector suffered a heavy selloff, with the Philadelphia Semiconductor Index falling more than 12%, and leading stocks such as Nvidia and Micron Technology dropping sharply. Echoing the market performance, domestic hard-tech companies are releasing development confidence through concrete actions. At midday on November 6, more than 10 technology leaders including Zhongji Innolight, Eoptolink, TFC Optical Communication, Dongshan Precision, Luxshare Precision, and Sanhuan Group collectively disclosed announcements on share buybacks and operating conditions. Previously, ChangXin Technology raised the upper limit of its buyback funds to 5 billion yuan, and companies such as Eoptolink and Hygon Information have also rolled out large buyback plans. Multiple interviewees believe that as domestic hard-tech companies continue to grow their operating performance and industrial competitiveness steadily improves, listed companies are demonstrating development confidence through real-money buybacks and increases in holdings, while long-term capital entering the capital market and market-stabilization mechanisms are also gradually improving. With multiple factors overlapping, the value support for China's hard-tech assets is increasingly strengthening, and they are expected to gradually break away from reliance on overseas market valuation systems and industry cycles, form a more independent value judgment system, and achieve a shift from an "independent narrative" to "independent pricing."
