it will not affect. Futures have the function of hedging. Hedging refers to futures trading with the purpose of avoiding spot price risk. Hedging transactions can help to avoid price risks and achieve the purpose of hedging, because the futures price trend of the same commodity is basically consistent with the spot price trend. For example, on March 1st, a copper processing factory needed 5 tons of copper as raw material one month later. The current spot price of copper is 17, yuan per ton. In order to lock in the cost and avoid the risk of price increase, the factory bought 5 tons of copper futures for delivery in April on the same day, and the price was 17 1 yuan per ton. By April 1st, the spot price rose to 17 1 yuan per ton, and the futures price rose to 17,2 yuan. At this time, the factory sold the 5-ton futures contract it had held. The profit from liquidation is 5 yuan [(17 2- 17 1)x5], that is, the factory earns 5 yuan in the futures market.
