Linde is reportedly the world's largest industrial gas company, with a strong position in the market. The company's operations and strategy are said to support long-term growth prospects, and the industrial gas sector is experiencing record project backlogs, potentially driven in part by the US market. However, it is unclear whether this is a good time to buy Linde's stock, with some outlets suggesting it may not yet be a buy and others discussing potential benefits from a helium shortage.
