Concept Clarifier – AUM
Assets Under Management (AUM) represents the money which is managed by a mutual fund in a scheme. Adding AUMs for all schemes of a fund house gives the AUM of that fund house and the figure arrived at by adding AUMs of all fund houses represents the industry AUM. AUM is calculated by multiplying the Net Asset Value (NAV – explained in detail later) of a scheme by the number of units issued by that scheme.
A change in AUM can happen either because of fall in NAV or redemptions. In case of sharp market falls, the NAVs move down, because of which the AUMs may reduce.
