Profit and loss, as the name implies, is the situation of profit and loss. Generally, it is necessary to distinguish between floating profit and loss and realizing profit and loss. Take fund investment as an example. After purchasing the fund share, the net value of the fund share changes, resulting in a change in profit and loss. The calculation formula of floating profit and loss is roughly as follows: market value of current account assets+cash income from historical dividends+total amount confirmed by redemption of shares-investment principal. It should be noted that the investment principal is directly put into the purchase fund, which may be the amount transferred from the fund. For example, if I bought a fund A with 10000 yuan, I just sold half of it on Monday and got 5000 yuan. A month ago, I paid a dividend of 1 1,000 yuan in cash, and the assets in my account were still 3,200 yuan, so the current profit and loss of investment cash A was: 5000+ 1 1,000+3,000 yuan. As for the total profit and loss, it should be the overall profit and loss of all the investments in your account, and the factors of change are relatively large. I know that ICBC's online banking has a display of floating profit and loss, but it is never accurate after careful calculation.
