In our daily life, when it comes to futures, it can be said that it can be seen everywhere. For example, you want to travel in a month, but you are worried about the price increase of air tickets, so you booked the air tickets at a discounted price in advance, which is equivalent to a small futures transaction. In the financial market, futures have different faces. Futures in financial transactions are also called futures contracts. In fact, they are just a paper contract, which is uniformly formulated by the futures exchange and has standard terms, allowing listing and trading. The holder of a futures contract has the right to deliver a certain amount and quality of assets at a certain time in the future. To give a simple example, we bought a house with a price of 6.5438+0 million yuan, made a down payment of 20%, and signed a contract. Futures is called this leverage ratio. The developer said that the house of 6.5438+0.5 million yuan was turned into a school district because a school was built next to it. A down payment of 200,000 earned 50,000. 1 10,000 house depreciated to 500,000, and the down payment was 200,000. The result is equivalent to losing 500 thousand. This is the leverage ratio in futures, and it is also one of the reasons why many people earn a lot or lose a lot by speculating in futures. The earliest futures contract in the world was invented in 1865 and was originally traded by Chicago Board of Trade. Up to now, there are two kinds of assets in futures trading, one is bulk commodities, such as corn, sugar, gold, silver, copper and iron, and the other is financial assets or financial indicators, such as foreign exchange and bonds. Every futures contract will have standardized terms, which specify the types of corresponding assets in detail. The only thing that is not stipulated is the price, which is determined by the investors who participate in futures trading in the market. However, the futures contract stipulates the minimum variable price, and investors must quote an integer multiple of this price every time. In addition, the price limit also limits the price of futures contracts not to exceed or fall below a certain value in one day.
