Personally, this means that the downstream demand for copper is increasing, and there is a great possibility that copper prices will rise in the future. Because it depends on whether the change of copper inventory is short-term or phased. A day or two's change is hard to explain this problem. There are many reasons for the decrease of inventory, which will also lead to different results. First of all, you need to know the reason for the decrease. Has the export decreased? Is the demand increasing? There is still an accident. But generally speaking, the reduction of inventory is beneficial to the price, that is, it is one of the factors that increase the price.

However, whether it can cause price rise is closely related to other aspects of the subject, such as external prices, exchange rates, interest rates, etc. The big market during this period is mainly caused by the decline of international crude oil, and the fundamentals of this problem itself have been eliminated. In other words, the previous sharp decline was not caused by the fundamental changes of a specific commodity, but by the strong negative interest rates of all commodity futures.

Secondly, in industrial and commercial enterprises, inventory is usually called goods in warehouses. Warehouse goods include raw materials, auxiliary materials, low-value consumables, equipment spare parts, tools, labor protection supplies, administrative office supplies, laboratory chemicals and finished products. Insufficient inventory means that the inventory of the above items does not reach the minimum storage capacity of the warehouse inventory. In industrial enterprises, inventory is insufficient, some dimensions are specific to orders, and some dimensions are specific to monthly warehouse management control indicators. Minimum standard storage? .

The solutions to the shortage of inventory are as follows: in the first case, when the inventory is insufficient, the purchase plan of the shortage of materials is calculated according to the standard BOM of the materials required by the order and finished products; In the second case, the supply department knows the shortage quantity in the system, that is, the quantity to be purchased, for the minimum storage quantity of the warehouse monthly inventory mode. Check the purchasing cycle table of each material according to the purchasing time and arrival inspection time, and send the purchasing plan in time according to the table.
