* * * The same fund is also called an indefinite investment company. An investment trust organization that provides investments for small business owners and distributes stocks that can be converted into cash at any time. In western countries, due to the developed securities market and serious speculation, people can't decide which stock to buy or when to buy or sell. Some people who have experience in securities business, starting from the pursuit of income, capital appreciation and even speculation, organize the "same fund", raise funds by themselves, and pool investors' funds to buy various securities. At the same time, they provide investors with alternative purchase plans and collect commissions from them.

Investors can also exchange investment types by paying some fees as needed. The price of selling stocks is not directly affected by the market, but only depends on the price of securities held by the same fund. Usually, each share only represents the net asset value of the same fund (total assets MINUS total liabilities divided by the number of shares). In recent years, the International Monetary Fund (IMF) has also appeared in some parts of China, which has played an active role in raising funds for economic construction and prospering the securities market.
