英文解释：

The cumulative profit and loss of funds refers to the profit and loss situation of fund investors since purchasing the funds. Specifically, the cumulative profit and loss includes the gains and losses made by investors during the holding period of the funds, whether it is the principal invested at the time of fund purchase or the funds received at the time of fund sale, which will affect the calculation of cumulative profit and loss. The amount of cumulative profit and loss depends on multiple factors, including the rise and fall of fund net asset value, investors' holding time and investment amount, etc. For investors, understanding the situation of fund cumulative profit and loss is very important, which can help them evaluate their own investment income and loss situation and formulate more reasonable investment strategies.
