Delivery risk means that investors can hedge their positions before the futures contract expires. If the hedging operation cannot be completed in time, it will bear the delivery responsibility and must make up enough funds or physical objects for delivery. For investors, if they don't choose delivery, it is best not to hold the corresponding contract when the delivery date is approaching. This is a special point of the futures market compared with other investment markets. New investors should pay special attention to this link and try not to hold the contract in their hands until it is close to delivery, so as not to fall into the predicament of being "forced".
