5. Differences in management's perception of the market. The American stock market is an IPO registration system. Anyone who wants to go public can, but it must conform to the market rules, strictly abide by the market rules and regulations, and make market returns. Otherwise, they will bear the risk of being fined, bankrupt or imprisoned. So many companies know that it is not easy to go public. A shares are subject to the examination and approval system, and the management only needs to solve the problem of financing difficulties for enterprises. As for listed companies, they are dismissive of the return of the market. Some companies have not paid dividends for years, and no one has asked. Some companies think that the market is just a piece of "Tang monk meat". They don't eat for nothing, they don't take it for nothing, they take it for nothing. Some companies even regard the market as an ATM for them to get rich.

6. The difference between trading rules, the rules of the American stock market are quite perfect, no one dares to manipulate the market at will, violators will be severely punished, and no one dares to take great risks to violate the rules. A shares impose a fine of 600,000 on violators. The penalty is too light and the risk is minimal. Even if you are punished, you can still profit from it, so some people dare to violate the rules.
