The Shanghai Composite rose 0.2% to close at 3,923, while the Shenzhen Component dropped 0.3% to 13,726 on Monday, as market sentiment remained cautious amid escalating Middle East tensions. The conflict entered its fifth week, with President Trump warning that the US could “take the oil in Iran,” including seizing Kharg Island. In addition, hostilities widened as Iran-aligned Houthi forces launched missiles toward Israel, heightening risks to energy supply routes. Adding to investor unease, a few Chinese-linked vessels reversed course near the Strait of Hormuz, an unusual development given the traditionally stable ties between Beijing and Tehran. Losses were led by Midea Group (-3.6%), Luxshare Precision Industry (-3.7%), and Sungrow Power Supply (-3.8%). In contrast, energy stocks were among the key performers amid higher oil prices, particularly PetroChina (3.1%) and China Petroleum and Chemical Corporation (1.2%).
