The per-unit value of an investment fund = (total assets − liabilities) ÷ number of units.
Net Asset Value (NAV) is the per-unit price of an investment fund, computed as (total fund assets − liabilities) ÷ number of outstanding units. It is the price at which you buy and sell a fund unit. NAV updates periodically — daily or weekly depending on the fund — as the value of the fund's holdings changes. A rising NAV means the fund's investments gained value; a falling NAV means the opposite. Note that NAV is not necessarily the total return, since some funds distribute dividends that reduce NAV at the moment of distribution. FoudaLens shows NAV history and returns for every fund.
