Assets Under Management (AUM)

Assets Under Management (AUM) is a key metric in the financial industry that quantifies the total value of funds, assets, or investments managed by a financial institution, such as an investment firm, mutual fund, or hedge fund. It provides insight into the size and scale of a financial entity’s operations and its ability to influence financial markets.

According to a report by the Investment Company Institute (ICI), total mutual fund assets under management in the United States reached $22.6 trillion as of December 2020[^1^].

Understanding AUM

AUM includes a diverse range of assets, such as stocks, bonds, cash, real estate, and other securities that are actively managed by the institution on behalf of clients or investors. Financial institutions charge management fees based on a percentage of AUM, which helps fund their operations and services.

Significance of AUM


AUM is a critical metric as it reflects an institution’s ability to attract and retain investors, its market influence, and its financial health. Institutions with higher AUM often have more resources to research and analyze investment opportunities, provide a wide range of services, and potentially negotiate favorable terms with third parties.

Market Impact

Institutional investors with substantial AUM can influence asset prices and market trends due to the sheer size of their investments. Large trades made by institutional investors can impact supply and demand dynamics, affecting market liquidity and prices.

Investment Strategies and Objectives

AUM is also an indicator of an institution’s investment strategy and areas of expertise. Different institutions focus on diverse asset classes, industries, or geographic regions based on their investment mandates and client preferences.


Challenges and Considerations

While high AUM can be a sign of success, it also presents challenges. Managing a large pool of assets requires careful risk management, diversification, and adherence to regulatory and compliance standards. Institutions with significant AUM also face increased scrutiny from regulators and investors.

Market Trends and Evolution

The asset management industry continues to evolve, influenced by technological advancements, changing investor preferences, and shifts in global economic conditions. The rise of passive investing through ETFs and the integration of sustainable and ESG (Environmental, Social, Governance) factors into investment decisions are reshaping the landscape.

Closing Thoughts


Assets Under Management is a vital metric that provides insights into the scale, reach, and influence of financial institutions. As the financial industry evolves, AUM remains a fundamental measure of an institution’s ability to navigate market trends, serve clients, and achieve investment objectives.
