Stocks are physical objects. How many shares you buy determines your shareholding ratio in this listed company. When the proportion is the highest, you are the largest shareholder. In America, you buy 1 share, which is also called a shareholder. In China, there is no concept of owner.

Stock index futures trading positions in the Shanghai and Shenzhen 300 Index include short positions and short positions.

Each 300 yuan is designed by the financial exchange according to the situation of China's capital market, and at the same time, it wants the institution to become the dominant in the futures market. Now the value of each lot is100W. If the exchange stipulates 30 o'clock every hour, the value is 10w.

It can be seen that the index point is not a physical object, but an artificially specified value. 1 share and 1 common goods. Can 10 yuan be defined as 10 yuan and 100 yuan as 100 yuan? Australia wants to raise the price of iron ore, and the final result is also the result of the game between the two sides.

So when you buy and sell stock index futures, you don't give money to anyone. This money is put in the exchange as a guarantee for your execution of the futures contract. The more money you have, the more futures contracts you are allowed to buy and sell, and the daily clearing company will remit the money. This is the so-called debt-free system.
