[Illustrated Bull and Bear Stocks] Phosphorus chemical concept leads in gains, oil and gas exploration sector performs actively

Caixin News, March 1 — This week, the three major A-share indices rebounded and surged, with the Shanghai Composite Index rising 1.98% for the week, the Shenzhen Component Index up 2.80%, and the ChiNext Index increasing 1.05%. The metals and oil & gas extraction sectors led the gains, while small metals and phosphate chemical concept stocks performed actively.

This week, phosphate chemical concepts saw the largest gains, with China Jinmao up 46.23% and Qing Shui Yuan up 30.17%. In terms of news, on February 18, U.S. President Trump signed an executive order invoking the Defense Production Act, elevating elemental phosphorus and glyphosate herbicide to a matter of national security priority, citing shortages of these materials as a direct threat to national security. Currently, as the world’s largest consumer of glyphosate, this move is expected to increase domestic agricultural chemical production costs in the U.S., pushing global battery manufacturers to accelerate securing upstream phosphate mineral resources, potentially giving phosphate mining companies stronger premium space.

This week, the oil & gas extraction sector performed actively, with Tongyuan Petroleum up 41.10% and Intercontinental Oil & Gas up 25.71%. Regarding news, on February 13, 2026, the Ministry of Finance, General Administration of Customs, and State Taxation Administration jointly issued a notice on “Tax Incentives for Energy and Mineral Exploration and Development During the 14th Five-Year Plan,” which stipulates that for offshore oil (natural gas) exploration and development projects, imported equipment, instruments, and spare parts that cannot be produced domestically or do not meet performance standards are exempt from import tariffs. Meanwhile, the U.S. and Israel launched a surprise attack on Iran, raising concerns about potential disruptions in Iranian oil production and shipping through the Strait of Hormuz, which could increase volatility in international oil prices amid tense Middle Eastern tensions.

In terms of main capital inflows this week, major funds net bought over 2 billion yuan in Baogang Steel, Hudian Co., Northern Rare Earth, Huasheng Tiancheng, Dongshan Precision, China Shipbuilding, and Shenghong Technology. Major funds net outflows exceeded 30 billion yuan from Zijin Mining, CATL, New Easy Sheng, Guangxian Media, China Duty-Free, and Wangsu Technology.
