Unit net worth and accumulated net worth are two common concepts in investment funds. Every investor will pay attention to these two indicators when buying funds, because these two indicators are of great significance for measuring the income and value of funds. This paper will analyze the meaning of unit net value and accumulated net value from the perspectives of fund definition, calculation method and application scope. First, let's look at what a fund is. A fund is a financial product that collects the funds of multiple investors. According to the established investment strategy, fund companies or fund managers effectively allocate and manage various assets such as stocks, bonds and futures, so as to spread investment risks and improve investment returns. Investors of funds hand over their own funds to fund companies or fund managers for investment, and the profits and losses of funds ultimately belong to investors.

Net asset value (NAV) refers to the price of each net asset of a fund. The calculation method of unit net value is to divide the total net asset value of the fund by the total share of the fund. The net assets are the total assets of the fund minus liabilities, and the total share is the total issued share of the fund. The unit net value reflects the net asset value of each fund, and it is also the reference price when investors buy or redeem the fund.

CumulativeNetAssetValue refers to the sum of the accumulated unit net value of the Fund since its establishment. The accumulated net value is calculated once a day from the date of the establishment of the fund, and is constantly updated with the operation of the fund. Cumulative net value is a measure of the historical performance of the fund and an important reference for investors to evaluate the investment effect of the fund.

From the calculation method, both the unit net value and the accumulated net value are obtained by calculating the net asset value of the fund. Net assets will change with the investment operation of the fund and changes in the market. The calculation of daily net assets is based on today's asset value minus today's liabilities. This process needs to be handled by the fund manager and be open and transparent.

From the application point of view, both unit net worth and accumulated net worth are of great significance to investors. The unit net value can reflect the fund's net asset value, and investors can decide when to buy or redeem the fund according to the unit net value. When the unit net value rises, it means that the investment value of the fund increases and investors can get higher returns. On the contrary, the decline in unit net value means that the investment value of the fund declines, and investors may face losses. Unit net value is also the calculation basis of fund return.

The accumulated net value can reflect the historical performance of the fund. By observing the cumulative net value curve of the fund, investors can understand the investment income and fluctuation of the fund. A relatively stable cumulative net value curve may mean that the risk of the fund is low and it is suitable for conservative investors. The relatively volatile cumulative net value curve may represent the higher risk of the fund and is suitable for investors with strong risk tolerance.

In a word, unit net worth and accumulated net worth are two important concepts in investment funds. The net unit value is the price of each net asset of the fund, which serves as the reference price for investors to buy or redeem the fund. Cumulative net value is the sum of cumulative unit net value since the establishment of the fund, which is used to evaluate the historical performance of the fund. Investors can make investment decisions by understanding and analyzing the unit net value and accumulated net value, and choose appropriate funds according to their risk tolerance.
