Advantages are:

1. FOF funds directly invest in funds, rather than directly participate in the stock market, so the risk is small;

2. FOF fund is a "basket fund", so the stability of funds is strong and the income is relatively stable;

3. If you buy a "basket fund", it will be selected twice by the fund manager, which will effectively reduce the non-systematic risk.

Disadvantages:

For investors with risk preference, the income of FOF funds is not as high as that of stock funds or hybrid funds, so they don't like this kind of funds very much, and because they buy a package of funds, they need to pay the handling fee twice.
