What Is AUM in Finance?

When evaluating a portfolio manager, assets under management (AUM) is one metric investors consider.

Among other variables such as management performance, experience, disciplinary history, and other offered services, a greater AUM can be an indicator of a manager who has demonstrated proficiency.

Investment advisors that oversee more than $25 million in AUM must register with the Securities and Exchange Commission (SEC).

Advisors overseeing less may register with state securities administrators.

AUM Payment and Fees

Managers may charge a percentage of the total AUM they manage for a client for their services, such as 1%.

At present, the financial institution with the most assets under management is BlackRock, with over $6.8 trillion in assets.

In second is Vanguard Group with just over $6 trillion, followed by UBS Group with $3.26 trillion, Fidelity with $3.2 trillion, and State Street Global Advisors with $3.12 trillion.

AUM vs NAV

NAV, or Net Asset Value, is the total value of assets minus all its liabilities of a fund, such as a mutual fund or ETF, often shown on a per-share basis.

NAV shows what price shares in a fund can be bought and sold at.

AUM by contrast refers to the value of assets managed by an individual or firm, not a fund.

Unlike NAV, AUM is in reference to the total value of assets being managed rather than expressed on a per-share basis.

AUM for ETFs

One of the metrics for determining the quality of an ETF, or Exchange Traded Fund, is AUM, or Assets Under Management.

The more assets that are contained in an ETF, as well as the higher the volume of trading that occurs, the less likely shares of the fund are to swing in price.

This makes these types of funds safe and stable investments.
