Chinese Stocks Fall by Midday; Defense Sector Rallies on Geopolitical Tensions

Chinese equities broadly declined during Tuesday's morning session, with the tech-focused ChiNext index leading losses. The market saw a clear divergence as funds flowed out of high-valuation technology stocks and into sectors like defense and utilities, driven by heightened geopolitical tensions and domestic policy news.

Midday Market Snapshot

By the midday close on Sept. 2, China's three major stock indexes were all in negative territory. The market's performance was characterized by widespread declines, with nearly 4,000 individual stocks falling across the Shanghai and Shenzhen exchanges.

• The Shanghai Composite Index fell 0.82% to 3,947.26.
• The Shenzhen Component Index dropped 1.71% to 13,635.33.
• The ChiNext Price Index slid 2.18% to 3,319.39.

In contrast, the Beijing Stock Exchange 50 Index bucked the trend, rising 4.55%. Total half-day trading turnover for the Shanghai and Shenzhen markets was 1.21 trillion yuan, a decrease of 140.3 billion yuan from the previous trading day, according to data from Zhitong Finance APP.

Sector Divergence and Capital Flows

Capital flows showed a distinct rotation into defensive and industrial names. Net inflows were recorded for the national defense, building materials, and power grid equipment sectors. Conversely, significant outflows were seen from electronics, non-ferrous metals, and semiconductors. The electronics sector alone saw net institutional outflows of approximately 11.8 billion yuan.

Among individual stocks, Far East Smarter Energy (600869.SS) attracted the largest net capital inflow of over 1 billion yuan. In contrast, Zhongji Innolight (300308.SZ) experienced the largest net outflow, with more than 2.7 billion yuan being pulled by institutional investors.

Key Market Drivers

Several factors influenced sector performance. The defense and military-industrial sector rallied strongly following reports of escalating conflict between the U.S. and Iran. According to CCTV News, recent U.S. military strikes on Iranian targets prompted counter-attacks, fueling investor interest in defense-related assets.

Power grid equipment stocks also gained after China's National Energy Administration held a meeting on Sept. 1 to deploy work on building new types of power grids. The agency highlighted the need for new technologies to meet an expected 5% annual growth in electricity demand during the "15th Five-Year Plan" period.

Elsewhere, PCB-related stocks rebounded on news of price hikes for copper clad laminates by major producers, citing rising raw material costs. The coal sector remained active amid expectations of a fourth round of price increases for coke, a key steelmaking ingredient.
