The "goods" corresponding to this contract are called the subject matter. Generally speaking, the "goods" to be speculated in futures are the subject matter, which is embodied by contract symbols. For example, SR 1 10 1 is a futures contract symbol, which means a contract delivered in the month of 20 1 1, and the subject matter is white sugar.
The difference between futures and stocks:
1, the trading mechanism is different. You can only buy more stocks and sell short futures.
2. The leverage coefficient is different. The leverage coefficient of stocks is 1: 1. With the margin system, the leverage coefficient of futures can be 1:5 or 1: 10.
