It's simple.

The original net value is 3 yuan, and the market price is 2. 5 yuan, bonus . 5 yuan,

Original discount: (3-2. 5)/3=16.67%

After dividends: (2. 5－2）/2。 5 = 2%

The net value will not go up because of dividends. After dividends, the net value will be deducted from the market price at the same time, but the net value will be announced once a week. It is likely that when the market price has deducted dividends, the net value has not yet been announced, so it seems to be much higher than the market price.
