Gansu Dunhuang Seed Group, Xinjiang Sailimu Modern Agriculture, Wanxiang Doneed, and Cnfc Overseas Fisheries hit the limit up. Chicago wheat futures prices reached their highest level in three years, as HSBC pointed out that the agricultural supply chain faces multiple impacts from Middle Eastern conflicts, regional wars, and extreme weather events like El Nio.

HeBei Jinniu Chemical Industry, North Huajin Chemical Industries, Shanxi Lu'an Chemical Technology, Sichuan Lutianhua, and Guizhou Chitianhua also hit their daily limit up. Institutional research reports indicated a tight global supply for chemical production capacity and maintenance of low downstream inventories, with anticipated concentrated release of replenishment demand. Gold jewelry remained active, with Shenzhen China Bicycle recording a seventh consecutive limit up, and Leysen Jewellery Inc. hitting the limit up. The medical and semiconductor sectors declined, with biopharmaceuticals, medical services, semiconductors, and communication equipment showing the most significant decreases. Hot Sectors 1. **Agriculture and Fisheries**: The fisheries, planting, and Shenzhen Agricultural Power Group processing sectors all strengthened, with fisheries up 4.55%, planting up 2.16%, and Shenzhen Agricultural Power Group processing up 2.65%. Multiple stocks including Gansu Dunhuang Seed Group, Xinjiang Sailimu Modern Agriculture, Wanxiang Doneed, Cnfc Overseas Fisheries, and Xinjiang Guannong hit their daily limits. This surge was catalyzed by Chicago wheat futures prices reaching their three-year peak, alongside HSBC's warnings about the agricultural supply chain facing multiple impacts from Middle Eastern conflicts, regional wars, and extreme weather conditions like El Nio. 2. **Chemicals**: The sectors for chemical raw materials, chemical products, agrochemical products, refining, and trade saw a collective rise. Stocks such as HeBei Jinniu Chemical Industry, North Huajin Chemical Industries, Shanxi Lu'an Chemical Technology, Sichuan Lutianhua, and Guizhou Chitianhua hit their daily limits. This growth was propelled by institutional research reports indicating tight global chemical production capacity and low downstream inventories, with future replenishment demand expected to be concentrated. 3. **Gold and Jewelry**: The jewelry sector rose by 3.42%, and gold-related stocks were repeatedly active. Shenzhen China Bicycle recorded a seven consecutive limit up, Leysen Jewellery Inc. hit its daily limit up, and Baiyin Nonferrous Group rose nearly 6%. Adjustment Sectors The medical and semiconductor sectors led the declines. Biopharmaceuticals, medical services, CROs, and vaccines experienced significant drops, with Anhui Wanbang Pharmaceutical Technology falling over 17% and Xinjiang Bai Hua Cun Pharma Tech declining over 7%. The semiconductor sector dropped by over 2%, with electronic chemicals and communication equipment also weakening. The aforementioned sectors had seen significant increases previously, leading to today's notable declines.
