Choosing how to operate is purely a personal hobby. Whether it is open or closed, the choice is of course the first net growth rate. The high discount on the base cover means that the performance is not good and no one likes it. Of course, some people say that they want this discount when they get it! Don't forget that the stock market is changing, and the net value of the fund will also fall.

If you don't want to be a band, buy an open one.
