I can't. In futures trading, futures contracts have a time limit. At present, the term of domestic commodity futures contracts is 12- 18 months. When the contract expires, all open commodity futures contracts must be delivered in kind, and special invoices for value-added tax need to be delivered or received. Therefore, if investors don't want or can't make physical delivery, can't deliver or collect special VAT invoices, they should close their positions before the time limit stipulated by the exchange. Not in the stock market, as long as listed companies do not withdraw from the market, they can always hold stocks.
If investors want to hold a commodity futures contract all the time to meet the needs of long-term commodity investment, they can close their positions near the delivery deadline and hold the contract in a further month by buying and selling in the market.
