The rise and fall of a Chinese naming day means that major stocks or markets are marked as rising in red and falling in green, which is the difference between the instantaneous price of a stock today and yesterday's closing price, marked as rising in red and falling in green. The estimated increase refers to the difference between the estimated net value of stocks and bonds held by the Fund and the increase in the net value of the previous trading day in the latest quarterly report of the Fund. Because it is estimated according to the quarterly report, there will inevitably be deviations, such as the high turnover rate of the fund, and the deviation will be even greater.

The daily increase is the difference between the net value actually calculated by the fund company after deducting the expenses according to the stock and bond assets held by the fund every day and the net value increase of the previous trading day. Price fluctuation = (current price-closing price of last trading day)/closing price of last trading day * 100%
