Economic Information Daily reports on the 23rd: The market continues to focus on the China-U.S. leaders' summit, with Chinese President Xi Jinping expected to depart for Washington later today to begin a state visit to the United States. After three consecutive days of gains, the Shanghai and Shenzhen stock markets pulled back, with the SSE Composite Index closing down 0.39% at 3969.52 points, the Shenzhen Component Index also down 0.64%, and the ChiNext Index ending 0.6% lower. Trading volume contracted, with total turnover in both markets amounting to only 1.76 trillion yuan (RMB, same below), a decline of 370.7 billion yuan or 17% compared to the previous trading day.

Looking at the market, advanced packaging, superhard materials, and other semiconductor supply chain sectors continued to strengthen, with Wald (Shanghai: 688028) closing up 4.8%. The AI boom is spreading; in recent months, several traditional superhard material listed companies, including Wald, have frequently issued announcements regarding investment and changes in fundraising, entering the diamond heat dissipation sector.

In addition, the real estate sector surged, with Vanke A (Shenzhen: 000002) rising 2.9%. Earlier, Reuters reported that Chinese regulators have provided window guidance to some commercial banks, temporarily not classifying or minimizing the classification of Vanke's overdue loans as non-performing, to avoid financial stability risks. Sources indicated that regulators have also requested certain banks to provide supportive measures such as deferred interest payments and loan extensions for Vanke to alleviate its short-term debt pressure.

On the downside, the shipbuilding sector led the decline, with the index dropping over 3%; AI application concepts adjusted broadly; agricultural and animal husbandry stocks also weakened collectively. (ry)
