The share of the fund is related to its income, and the income is directly proportional to the net value. The more the fund's net value rises, the more it will earn. The net value of the fund is the same as the stock price, and the rise and fall determine whether the fund is profitable or loss. The formula for calculating the net fund value is: the income of each fund = the net fund value of the day-the net fund value at the time of subscription-subscription fee-redemption fee.

Because closed-end funds are listed on the exchange, their buying and selling prices are greatly influenced by the relationship between market supply and demand. When the market supply is less than the demand, the buying and selling price of the fund unit may be higher than the net asset value of each fund unit, and then the fund assets owned by investors will increase; When the market supply exceeds demand, the fund price may be lower than the net asset value of each fund unit.

The transaction price of open-end funds is calculated based on the net asset value of the fund unit, which can directly reflect the level of the net asset value of the fund unit. In terms of fund transaction costs, investors have to pay a certain percentage of securities transaction tax and handling fee in addition to the price when buying and selling closed-end funds, just like buying and selling listed stocks.

Extended data:

Compared with investors' direct investment in the stock market, equity funds have the characteristics of risk diversification and low cost. For ordinary investors, individual capital is limited after all, and it is difficult to reduce investment risks by diversifying investment types.

However, if you invest in stock funds, investors can not only share the benefits of all kinds of stocks, but also spread the risks among all kinds of stocks by investing in stock funds, which greatly reduces the investment risks. In addition, investors who invest in stock funds can also enjoy the relative advantages of large-scale investment of funds, reduce investment costs, improve investment efficiency and obtain the benefits of economies of scale.

For investors, equity funds operate stably and have considerable returns. Generally speaking, the risk of stock funds is lower than that of stock investment, so the income is more stable. Not only that, after the closed-end stock fund goes public, investors can also get the bid-ask difference by trading on the exchange. After the fund expires, investors have the right to distribute the remaining assets.
