The omelet portfolio itself does not need additional management fees, and the management fees come from the funds inside the portfolio, because as long as it is an off-site subscription fund, the so-called omelet portfolio fund is just an omelet fund to help investors choose a group of relatively good funds to make a portfolio, so that investors can package them and buy them together.
For example, the omelet fund selects five funds as portfolio funds, so investors will pay management fees to these five funds by multiplying the principal by the rate after purchasing this portfolio.
