When some or all of the company's assets are cut into N parts and traded on the exchange, they are listed, and these are stocks that are bought and sold. A fund is a group of people who give their money to a person or institution to help them invest, including buying and selling stocks, bonds, and other things within specified limits. Futures are a guess at the price of a physical object at a specific time in the future. For example, I guess the price of soybeans in one month will be 10 cents, but the current price is 9 cents. Then I buy a contract and say that I guess the price of soybeans in one month will be 9 cents. 10 yuan. If it is 10 yuan a month later, you will make a profit of 1 yuan times the leverage. If it is 8 yuan, you will lose 1 yuan times the leverage. Leverage means that you can make a transaction of 10 yuan or other amounts of money with 1 yuan.
