According to data from the iFinD financial terminal, the spot price of argon stood at 2,750 yuan per metric ton on September 21, reflecting a 17.91% decline over the past week while still posting a cumulative 34.8% gain for the month. The latest reading on the same date showed no intraday change, although the monthly trajectory highlights a sharp rally from earlier levels.

This price surge stems from a convergence of reduced supply and recovering demand. As a rare gas produced as a byproduct of air separation, argon supply cannot be independently expanded since output is tied to the operating rates of air separation units. Regional maintenance shutdowns, high-temperature output reductions, and capacity cuts at petrochemical support facilities have all contributed to lower liquid argon production and depleted enterprise inventories, keeping supply tight across key industrial hubs in East and South China. On the demand side, traditional sectors such as stainless steel production, welding, and equipment manufacturing remain resilient, while semiconductor fabrication, AI computing chips, HBM memory, 3D NAND, and photovoltaic capacity expansions are further boosting demand for electronic-grade argon. This widening supply-demand gap continues to push spot quotes higher.

Stocks linked to the argon sector have shown notable momentum over the past 20 sessions. DeBang Technology has climbed 31.18% to 85.4 yuan, Fangbang Electronics has advanced 29.65% to 153.7 yuan, Tongyu New Materials has risen 26.35% to 204.6 yuan, Hongchang Electronics has gained 23.50% to 19.34 yuan, and Xilong Scientific has moved up 20.64% to 9.76 yuan.

Within the industry chain, argon originates upstream from air separation processes, which involve purification, liquefaction, and storage and transport to yield the final product. Downstream applications span metal welding, steel smelting, semiconductor manufacturing, lighting, and food preservation. It is important to note that commodity price increases do not necessarily translate into parallel gains for related stocks, as share prices are also influenced by corporate earnings, policy shifts, and overall market sentiment.
