The role of futures futures trading is an organized trading method developed on the basis of spot trading and conducted by buying and selling standardized futures contracts on futures exchanges. If people who invest in futures are classified, they can be roughly divided into two categories-hedgers and speculators. Hedging means spot hedging. Buying when bullish (that is, bulls) and selling when bearish (that is, bears) simply means buying (or selling) goods in the spot market and selling (or buying) the same kind of goods in the futures market at the same time, so that no matter how the price of the spot supply market fluctuates, it can finally achieve the result of losing money in one market and making profits in another market, and the loss amount is roughly equal to the profit amount, thus achieving the purpose of avoiding risks. The ultimate goal of investors is to obtain the price difference, and their income directly comes from the price difference. Speculators make a decision to buy or sell according to their own judgment on the trend of futures prices. If this judgment is the same as the market price trend, speculators can get speculative profits after closing their positions. If the judgment is contrary to the price trend, the speculator will bear the speculative loss after closing the position. Speculators take the initiative to take risks, and his appearance promotes the liquidity of the market and ensures the realization of the price discovery function; For the market, the emergence of speculators has eased the possible excessive fluctuations in market prices. Hedgers and speculators are indispensable in futures trading! Speculators provide the venture capital that hedgers need. Speculators use their own funds to participate in futures trading and bear the price risk that hedgers hope to pass on. With the participation of speculators, the price changes of related markets or commodities tend to be consistent, which increases the market transaction volume, thus increasing the market liquidity, which is convenient for hedgers to hedge contracts and freely enter and leave the market. The emergence of futures makes investors find a relatively effective channel to avoid market price risks, which is helpful to stabilize the national economy and establish and improve the market economic system!
