Funds can be divided into different types according to different standards: according to whether fund units can be increased or redeemed, they can be divided into open-end funds and closed-end funds. Open-end funds are not traded on the market (as the case may be), but are purchased and redeemed by banks, brokers and fund companies, and the fund scale is not fixed; Closed-end funds have a fixed duration and are generally listed and traded on the stock exchange. Investors buy and sell fund shares through the secondary market. Trust fund, also known as investment fund, is a collective investment model of "income * * * risk * * *": it refers to the way of collecting unequal funds of most investors who are uncertain in society through contracts or company issuing fund coupons (such as income coupons, fund shares, fund shares, etc.), forming a certain scale of trust assets, and handing them over to specialized investment institutions for diversified investment according to the principle of asset portfolio.
Purchase of funds: After completing the preparation for opening an account, citizens can choose their own time to purchase funds. Individual investors can bring the debit card and fund trading card of the correspondent bank to the counter of the agency outlet to fill in the fund trading application form (institutional investors need to affix the reserved seal), and must submit the application before the day of subscription 15: 00, and the counter will accept and receive the receipt of fund business. Two days after handling the fund business, investors can print the business confirmation at the counter. After the fixed investment, no matter how the market fluctuates, they will buy a fixed amount of funds with different net worth every month, automatically forming an investment mode of lightening positions on rallies and adding positions on dips, so that the average cost is at the middle level of the market. The fluctuation range of the whole year will be greater, and the risk of direct one-time investment will be greater. However, if you choose to invest regularly and stick to it, it will smooth the investment cost in the long run. The general starting point of fixed investment business is 100 ~ 300 yuan, which greatly lowers the investment threshold and provides convenience for small investors, so regular fixed investment is more suitable for working class.
