The reason why the fund does not rise during the National Day is that it does not trade on legal holidays. The fund will not increase during the National Day, and the increase or decrease is determined by the investment target. For example, stock funds mainly invest in a basket of stocks, and the rise and fall of the fund is determined by this basket of stocks. When the invested stock goes up, the fund goes up, and when the invested stock goes down, the fund goes down. It should be noted that money funds and bond funds will also calculate the income on legal holidays, and the funds will only rise and fall during trading hours.
