When the stock market generally rises, it is true that the net value of some fund units with 95% or even 98% stock positions has increased rapidly.

Not all the fund's money is invested in stocks, but also in bonds, and some funds should be reserved to deal with the redemption of the people.

A high proportion of positions refers to a high proportion of funds invested in stocks. The more stocks you buy, the more money you naturally make.

Large scale is not necessarily good, because fund managers are difficult to operate and dilute the profits of the people. Because more people buy the same fund, the average profit is less.
