Do you know about futures? It is a standardized contract in which buyers and sellers play with the future market price of a commodity as the target.

Stock index futures is a kind of futures, and the target is the stock price index. At present, the only variety is the Shanghai and Shenzhen 300 Index.

Conclusion: Futures, not stocks. Not stock trading.

The core difference between futures and stocks is that the futures market is a "zero-sum game", that is, the total income of all investors or speculators in the futures market adds up to zero (regardless of handling fees). The total returns of all investment speculators in the stock market add up to positive. Because all listed companies represented by stocks will increase in value in the long run, for example, the total profits of all listed companies in Shanghai this year are more than one trillion.

Other differences include leverage ratio (the amount allowed to borrow money for investment), market capacity (if you are a large fund, the amount you can trade) ... you don't look like it), the convenience of shorting profits, the entry threshold (minimum investment) and so on. By the way, there is also a big difference in handling fees.
