There are two types of corporate funds: 1. Closed-end closed-end funds are operated by investors purchasing company shares to form a joint-stock company.

The shares issued by the company can be listed and traded on the stock exchange, and their prices are determined by supply and demand in the market.

The number of shares issued by the company is fixed. After the issuance period expires, the fund will be closed and no more shares will be added.

Investors are not allowed to withdraw their shares after purchasing the stocks, that is, they are not allowed to ask the fund company to buy back the stocks, and they are not allowed to add new investments.

If investors want to cash out their stocks, they must transfer the stocks to the stock exchange.

2. In principle, investment companies in open-end funds only issue one type of stock (common stock). Shareholders can decide to withdraw their shares or expand their shareholding ratio in the company based on market conditions and their own investment decisions.

In other words, the company's total fund amount is not closed, but can be added.

Some people call it additional investment funds for this reason.
