AUM (Assets Under Management)
AUM (Assets Under Management) is the total market value of assets that a fund or firm manages on behalf of its clients, serving as a key indicator of size, scale, and credibility.
What Is AUM?
AUM, or Assets Under Management, represents the total market value of all investments that a fund manager, financial institution, or investment firm manages for its clients at a given point in time. This includes stocks, bonds, cash, real estate, and other securities held across all client accounts. AUM is one of the most widely cited metrics in the investment industry, used to gauge the size, influence, and operational scale of a fund or manager.
How Is AUM Calculated?
AUM is calculated by summing the current market value of all assets managed by the institution or manager, including any cash or equivalents. The value fluctuates daily based on market prices, capital inflows (new investments), and outflows (redemptions or withdrawals). Some firms may include only discretionary assets (where the manager has trading authority), while others also count advisory or non-discretionary assets.
Why Is AUM Important?
AUM is a crucial metric for several reasons:
Indicator of scale and credibility: A higher AUM often signals a fund’s popularity, stability, and ability to attract and retain investors.
Liquidity and efficiency: Larger AUM typically means greater liquidity, making it easier for investors to buy or sell shares without moving the market.
Fee structure: Management and advisory fees are usually calculated as a percentage of AUM, so it directly impacts a firm’s revenue.
Regulatory and operational thresholds: In some jurisdictions, AUM determines the level of regulatory oversight or reporting required.
Investor confidence: Many allocators and institutions use AUM as a proxy for manager quality and operational robustness, though it should be considered alongside performance and other due diligence factors.
Example: AUM in Practice
If a mutual fund manages $1 billion in stocks, $500 million in bonds, and $100 million in cash, its total AUM is $1.6 billion. As markets fluctuate or investors add/withdraw capital, the AUM rises or falls accordingly. For institutional managers, AUM can range from a few million to hundreds of billions of dollars, reflecting the breadth of their client base and investment reach.
Key Considerations
Not a guarantee of performance: While a high AUM suggests scale, it doesn’t necessarily indicate superior returns. Smaller funds may be more agile, while very large funds can face challenges deploying capital efficiently.
Varies by firm and asset class: The definition and calculation of AUM can differ between organizations, depending on what assets are included and whether they count discretionary or advisory assets.
