To put it simply, the amount of fund holdings is the number of fund shares that a fund can trade now, that is, the total number of fund shares.
We all know that closed-end funds can't be redeemed at will during the closed duration, and the total share remains fixed, while the fund share of open-end funds changes at any time according to the investment needs of investors.
Generally speaking, the scale of a fund's share can be found on the websites of general fund companies and third-party fund platforms, and you can know the holding amount when you know the scale of the share.
Fund holdings are affected by total assets, total liabilities and net fund shares, and fund holdings = (total assets-total liabilities)/net fund shares.
