Net unit value = net assets/total share.
For example, the net assets of a fund investing in stocks or other bills are 4 billion yuan, and the current total share of this fund is 3 billion. Then its unit net value is:
40/30= 1.3333 yuan.
The income of PetroChina should be included in the net value from the day of listing. It hasn't been thrown away. Of course, it is not included in the net value. The market is falling every day, and the income is of course from high to low. The net value of each fund is falling sharply.
