According to different investment objects, securities investment funds can be divided into: stock funds, bond funds, money market funds, hybrid funds and so on. If more than 60% of the fund's assets are invested in stocks, it is a stock fund; If more than 80% of the fund assets are invested in bonds, it is a bond fund; Money market funds that only invest in money market instruments; If it invests in stocks, bonds and money market instruments, and the ratio of stock investment to bond investment does not meet the requirements of bonds and stock funds, it is a mixed fund. From the perspective of investment risks, the risks brought by several funds to investors are different. Among them, equity funds have the highest risk, money market funds have the lowest risk and bond funds have the middle risk. Due to different investment styles and strategies, the risks of the same type of investment funds will be different. For example, stock funds can be divided into: balanced, stable, exponential, growth and growth according to the degree of risk. Of course, the greater the risk, the higher the rate of return; The risk is small, and the income is correspondingly lower.

The cumulative net value of the fund refers to the sum of the latest net value of the fund and the dividend performance since its establishment, which reflects the cumulative income since the establishment of the fund (minus the face value of one yuan as the actual income), and can reflect the historical performance of the fund in the operation process more intuitively and comprehensively. Combined with the operation time of the fund, it can more accurately reflect the real performance level of the fund.

Cumulative net value of fund share = net value of fund share+cumulative dividend amount of fund share after establishment.

For example, a fund once paid dividends, and every 10 dividend was sent to 2 yuan. If the net value of fund shares announced on that day is 1.02 yuan, the cumulative net value of fund shares is1.02+(2/10) =1.22 yuan.

If the net value of the fund you buy increases, it is greater than 0 after deducting the subscription fee and subscription amount, indicating the book profit.
