The margin for futures trading is 10%, which is the leverage ratio of one to ten. Example 65,438+0. Suppose a customer thinks that the price of soybean will rise, so he buys a futures contract at 3000 yuan/ton (soybean per hand 10 ton, and the margin ratio is about 10%), and then the price really falls to 3300. General business practice: buying cost: 3000 yuan/ton *1ton =30000 yuan profit: (3300 yuan -3000 yuan) × 10=3000 yuan return: 3000 yuan /30000 yuan * 10%. Hand x10% (margin) = 3,000 yuan/hand profit: (3,300 yuan-3,000 yuan) x/kloc-0 = 3,000 yuan (yuan) return rate: (profit) 3,000 yuan/(cost) 3,000 yuan */kloc- So I sold a futures contract at 3000 yuan/ton (soybean per lot 10 ton, the margin ratio is about 9%). Then, the price really fell to 2700 yuan/ton, and the customer bought a liquidation and completed a transaction. This can't be done in normal business, but it can be done in the futures market because futures trading can be sold first. You can make money even if you fall. Approximate investment cost: 3000 yuan/ton × 10 ton/hand×10% (margin) =3000 yuan/hand. Profit: (3,000-2,700 yuan) ×10 = 3,000 yuan. Yield: (1) The loss is the same as normal business, but the cost only accounts for 10%, and the commodity will have 10% in normal price fluctuation. If in normal business, there must be a return of 100%, that is, there is little chance that soybeans will rise from 3000 yuan to 6000 yuan.
