(1) Take risks. One of the main economic functions of the futures market is to transfer the risks of enterprise operators. To whom? Speculators, of course. Speculators are people who predict market trends and hope to get risk returns from price changes. Speculators intervene in the trading activities in the futures market to absorb the risks between commodity producers and users. They are people who are willing and dare to take risks in the futures market and hope to get risk returns for them. On the surface, speculation and gambling are similar. If both activities are high-risk and high-return, there will be winners and losers. The fees paid by futures speculators to brokerage companies are the same as those drawn from gambling, but in essence, speculation and gambling are completely different activities. The risk of gambling is man-made risk. When gambling does not exist, this risk disappears. The risk in the futures market is not man-made, but exists objectively in market economic activities. Even if the futures market does not exist, futures trading does not occur and speculation does not occur, this risk still exists and will not disappear. Speculators participate in futures trading activities, so that the economic function and market mechanism of the futures market can be fully displayed. To be sure, in a market without these risk takers, hedging transactions cannot be carried out, because the seller wants to get the highest possible price, while the buyer always wants to seize the lowest possible price. Without speculators to make up for this price gap, it is difficult for hedgers to hedge their futures contracts. (2) Increase market trading volume and enhance market liquidity. Due to the participation of a large number of speculators, the trading volume in the futures market has greatly increased, which is very beneficial for hedgers to establish and cancel hedging transactions, thus not affecting the price level, but enhancing market liquidity.
