We will also discuss how to calculate AUM, its relationship with fund performance, and the impact on fee structures. Stay with us as we delve into the fascinating world of investments and provide an insight into AUM.

Understanding Assets Under Management (AUM)

To better comprehend the AUM concept, we need to define it and discuss its importance in the investment realm. This will provide a solid foundation to explore the factors that influence AUM and how it relates to other aspects of investing.

What is AUM?

Assets under management (AUM) refer to the total market value of the investments managed by a financial institution or an individual investment advisor on behalf of their clients. These investments can include mutual funds, pension funds, hedge funds, private equity funds, and other types of investment accounts. AUM is an indicator of the size of the portfolio managed by that institution or advisor and is used to monitor their growth and success in managing investments.

It’s important to note that AUM doesn’t solely represent the amount of money that an institution or advisor has under their management. Instead, it reflects the market value of the investments in their portfolio.

Importance of AUM in the Investment World

AUM plays a crucial role in the finance industry for various reasons. For investors, AUM serves as a measure of the financial institution’s or advisor’s credibility and experience. Larger AUM indicates that the institution or advisor has been entrusted with more assets, which may lead potential investors to perceive them as more trustworthy and reliable. Similarly, investment professionals use AUM to gauge their performance and track the growth of their portfolios over time.

However, it’s worth noting that AUM alone doesn’t necessarily indicate the quality of an institution’s or advisor’s performance. AUM can be influenced by various factors, such as market performance, marketing efforts, and mergers and acquisitions.

Additionally, AUM can impact the fees charged by a financial institution or advisor. As AUM increases, so does their revenue from management fees. This can potentially benefit clients through economies of scale, as some institutions may lessen their fee percentages as AUM grows.

Relationship between AUM and Other Investment Metrics

LiquidityPotential correlation: Larger AUM can provide funds with greater liquidity and flexibility to meet investor redemptions.
Market ImpactPotential correlation: Funds with larger AUM may face challenges in executing trades without significantly impacting market prices.
DiversificationPotential correlation: Higher AUM can allow funds to diversify across a broader range of assets or markets, potentially enhancing risk management.
Influence on Corporate DecisionsPositive correlation: Funds with significant AUM can exert influence on corporate decisions through voting rights and engagement strategies.

Factors Influencing AUM

Many factors can affect the value of AUM, such as market performance, inflows and outflows, and specific investment strategies adopted by the financial institution or advisor. Understanding these factors is vital for investors when assessing potential investments or when evaluating the expertise of an investment professional.

1. Market Performance

One key factor that influences AUM is the performance of the financial markets. If markets experience a bullish trend, with indices or sectors registering significant gains, the value of the assets within the portfolio generally increases. Conversely, during market downturns, the value of the assets under management may decline. It is important to note that market fluctuations can have varying impacts on different types of investments and investment strategies.

For example, if the stock market is performing well, investors may be more likely to invest in equities, which can lead to an increase in AUM for financial institutions that specialize in stock investments. On the other hand, if the bond market is performing well, investors may be more likely to invest in fixed-income securities, which can lead to an increase in AUM for financial institutions that specialize in bond investments.

2. Inflows and Outflows

AUM is also affected by the inflows and outflows of clients’ funds. Inflows occur when new clients invest with the financial institution, or existing clients increase their investments. Outflows happen when clients withdraw their money or when their investment contracts mature. The overall AUM is positively impacted by higher inflows and negatively affected by higher outflows.

Financial institutions may use various strategies to attract new clients and retain existing ones, such as offering competitive fees and commissions, providing personalized investment advice and recommendations, and offering innovative investment products and services.

3. Investment Strategies

Different investment strategies can also influence AUM. For instance, more conservative investment approaches that focus on capital preservation may have less volatility in AUM, while aggressive strategies that prioritize high returns may experience significant fluctuations in AUM due to market movements. Moreover, the management approach used (active vs. passive) may also affect the performance of the AUM itself.

Financial institutions may use various investment strategies to achieve their clients’ investment objectives and maximize returns. These strategies may include value investing, growth investing, income investing, and alternative investments such as real estate, commodities, and hedge funds.

It is important for investors to understand the investment strategies used by their financial institutions or advisors, as well as the associated risks and potential rewards. By doing so, investors can make informed investment decisions and achieve their financial goals.

Calculating AUM

Calculating assets under management (AUM) is a crucial aspect of investment management. AUM is the total market value of assets that an investment manager oversees on behalf of their clients. It is an essential metric for investors to evaluate the performance of their investment managers and the growth of their portfolios.

The AUM calculation is relatively straightforward. It is the sum of the market values of all the individual assets in the portfolio. The formula is:

AUM = Σ (Market Value of Each Asset)

It is essential to note that the market value of assets must be updated regularly, particularly for volatile assets, to obtain an accurate representation of the AUM.

AUM Calculation Example

Let’s take an example to understand how to calculate AUM. Suppose an investment advisor manages a portfolio consisting of the following assets:

  • Stock A: 1000 shares, market value per share $30
  • Stock B: 2000 shares, market value per share $20
  • Bond A: face value $50,000, market value 95% of face value

To calculate the AUM of this portfolio, we need to sum the market values of each asset.

The market value of Stock A is $30 per share, and the advisor holds 1000 shares. Therefore, the market value of Stock A is 1000 x $30 = $30,000.

The market value of Stock B is $20 per share, and the advisor holds 2000 shares. Therefore, the market value of Stock B is 2000 x $20 = $40,000.

The market value of Bond A is 95% of its face value, which is $50,000. Therefore, the market value of Bond A is $50,000 x 0.95 = $47,500.

Now, we can calculate the AUM of this portfolio by summing the market values of all the assets:

AUM = $30,000 + $40,000 + $47,500 = $117,500

Therefore, the total AUM for this investment advisor’s portfolio is $117,500.

It is crucial to note that calculating AUM is just the first step in evaluating an investment manager’s performance. Investors should also consider other metrics, such as the manager’s investment strategy, risk management approach, and historical performance, before making investment decisions.

AUM and Fund Performance

When assessing the performance of funds, investors often use AUM as an indicator. However, there are limitations to relying solely on AUM when evaluating a fund’s success.

AUM as an Indicator of Fund Success

A higher AUM is often interpreted as a sign of a fund’s success. Large AUM typically indicates that more investors trust the fund manager’s expertise, which often results from years of solid performance. Furthermore, a growing AUM may signal continued good performance, as high-performing funds tend to attract more investors and capital.

Limitations of AUM in Evaluating Performance

  • AUM should not be the sole criterion for evaluating performance.
  • AUM can be influenced by factors unrelated to the fund’s performance, such as market movements and investor inflows/outflows.
  • Smaller AUM does not always indicate an inferior investment option, especially for new funds or those employing niche strategies.
  • Investors should consider multiple performance metrics, including absolute and risk-adjusted returns, to gain a comprehensive understanding of a fund’s success.

AUM and Fees

Lastly, let’s examine the relationship between AUM and fees. Understanding how fee structures work and the impact of AUM on fee negotiations can be crucial for investors when selecting a suitable investment vehicle and financial professional to manage their assets.

Management Fee Structures

Fees charged by financial institutions or advisors typically include management fees, which are a percentage of the assets under management. This percentage can vary depending on the type of investments managed, the level of services offered, and the expertise of the investment professional. Common fee structures include fixed percentages, tiered models where fees decrease as AUM increases, or performance-based fees that take into account the fund’s returns.

Impact of AUM on Fee Negotiations

A larger AUM can impact fee negotiations in two ways. First, as the AUM grows, the financial institution or advisor may become more open to negotiate and reduce their fees, as the increased revenue from managing a larger AUM could offset the fee reductions. Second, clients with sizeable investments may also have more negotiation power, as their assets contribute significantly to the institution’s or advisor’s AUM. This may lead to preferential fee arrangements for these clients.


Understanding assets under management (AUM) is essential for investors, as it provides insights into the size, performance, and reliability of the institutions or advisors managing their investments. By considering the different factors that influence AUM and how it relates to fund performance and fees, investors can make more informed decisions when entrusting their assets to financial professionals.
