The rise and fall of the fund refers to how much the fund has risen and how much it has fallen. The fund is increasing day by day, as the name implies, it is the increase of 1 day, and the annual increase refers to the increase of 1 year. If the daily increase is negative, it means that the net value of the fund falls on that day, and vice versa. Every day's ups and downs are calculated by yesterday's net value. For example, yesterday's net value was 1.88, and today's increase is 2 yuan, so the increase of the fund is: (2- 1.88)/2 = 6%. If the investor buys a fund of 10000 yuan, it means that the income of the day is 10000 yuan.

In addition, the fund details page will also indicate "the increase since the establishment of the fund". If the increase or decrease since its establishment is 150%, that is, investors subscribe for 100 yuan from the first day of the fund, the holding income is 15000 yuan.

Generally speaking, a fund needs to be held for a long time to see the return. For example, if the growth rate of the fund is very high since its establishment, but investors buy and sell frequently during the holding period, then there will be no such high income.

Price fluctuation is a description of price fluctuation, expressed in%. Price fluctuation = price fluctuation/yesterday's closing price * 100%. The value generated by comparing the latest transaction price (or closing price) of the current trading day with the closing price of the previous trading day is generally expressed as a percentage. In the China stock market, there is a limit to the rise and fall, so there is a saying of "limit to the rise and fall".
