Asset Under Management

The AUM full form is Asset Under Management (AUM), an important economic market metric used to analyse and measure the total market value of assets managed by a financial entity on behalf of its clients.

This article is intended to break down the concept of asset under management (AUM), specifically in the context of mutual funds, to help investors understand its significance and how it is calculated.

What is an Asset Under Management (AUM)?

At its core, AUM reflects the cumulative market value of all assets held within a mutual fund or managed by an investment firm. This includes the value of the investments and any capital and reserves maintained by the fund. Essentially, AUM is a measure of the total financial resources that a fund manages for its investors.

AUM provides a snapshot of the scale and scope of the assets a fund or firm oversees, encompassing everything from stocks and bonds to cash reserves and alternative investments.

The responsibility for managing AUM lies with fund managers, who make investment decisions to grow the fund’s assets. They strategise on asset allocation and select investments to maximise returns while managing risk.

Importance of AUM in Mutual Funds

The AUM of a mutual fund indicates its size, performance potential, and overall investor confidence. Let’s explore why AUM in mutual funds plays a vital role:

Indicator of Fund Size and Stability:

The size of a mutual fund, often represented by its AUM, indicates the total investments it holds. A higher AUM generally implies stability, as larger funds have a broad investor base and diversified portfolios. Also, a large AUM suggests that many investors trust the fund’s management. This often attracts new investors, boosting the fund’s growth.

Liquidity and Flexibility:

A higher AUM reflects that the mutual fund has more capital funds at its disposal, which can in turn improve its liquidity. Mutual funds with a higher AUM can buy or sell assets more efficiently, ensuring they can meet redemption requests from investors without significantly impacting the portfolio.

Impact on Fund Performance:

The AUM of a mutual fund company can affect its performance. A large AUM might limit a fund’s ability to achieve high returns, as it may be harder to find lucrative investment opportunities without impacting market prices. On the contrary, smaller funds often have more flexibility to explore niche investments and potentially generate higher returns.

Economies of Scale and Expense Ratio:

Funds with larger AUM can benefit from economies of scale, meaning the fixed costs of managing the fund (such as administrative expenses and management fees) are spread across a larger pool of assets. As a result, the expense ratio (annual fee charged to investors) tends to decrease as the AUM increases, which can lead to higher net returns for investors.

Influence a Fund’s Decision:

The size of a fund's AUM can directly influence its investment choices. For example, when a small-cap fund grows too large, it may struggle to effectively allocate capital, as the smaller companies it typically targets may not have enough capacity to absorb large investments. This can limit the fund’s ability to gain significant exposure in the companies it aims to invest in mutual fund.

Determines a fund's fees:

A fund’s AUM also affects the fees investors pay. SEBI's tiered fee structure mandates that larger funds have lower expense ratios while smaller funds may charge higher fees. However, investors should note that while larger funds may have lower fees, they often require higher minimum investments, potentially making them less accessible to some investors.

Impact of High AUM on Mutual Funds

A mutual fund’s Assets Under Management (AUM) can significantly influence its performance in the financial markets. Asset-rich funds tend to be more attractive to customers, as larger funds can provide better liquidity and stability.

The Indian mutual fund industry has experienced substantial growth, with its Assets Under Management (AUM) expanding more than fivefold over the past decade. According to ICRA Analytics, the industry is on track to surpass the ₹100 lakh crore AUM milestone within the next two to three years.

After crossing the ₹50 lakh crore mark in December 2023, the AUM grew rapidly, reaching ₹61.16 lakh crore by June 2024. This reflects a 38% increase from ₹44.39 lakh crore in June 2023. Additionally, the AUM rose nearly 4% month-on-month from ₹58.91 lakh crore in May 2024. Over the last ten years, the industry’s AUM has surged by 527%, growing from ₹9.75 lakh crore in June 2014 to ₹61.16 lakh crore in June 2024.

Investors often view AUM as an important metric when evaluating a mutual fund’s performance and ability to generate returns. However, AUM's impact varies depending on the type of fund.

1. Equity Funds:

Equity funds are designed to deliver solid returns and often aim to outperform the benchmark index. The performance of equity funds depends more on the skills and strategies of the fund manager than on the AUM itself. A high AUM does not necessarily guarantee higher returns for equity funds, as their success is more aligned with the manager's ability to navigate market fluctuations effectively.

2. Debt Funds:

For debt funds, AUM is a critical factor. A larger AUM allows debt funds to spread fixed expenses across a broader base of investors, resulting in lower costs per investor and potentially higher returns. This economy of scale benefits investors, as the fund’s operational costs are diluted, enhancing overall returns. Therefore, higher AUM in debt funds often correlates with better performance.

3. Small-Cap Funds:

In the case of small-cap funds, AUM plays a less significant role until it grows substantially. These funds focus on smaller companies, and a large AUM could lead to the fund manager holding a significant portion of a company’s shares, which can affect market liquidity. Small-cap funds typically prefer a leaner AUM to maintain flexibility and agility, often relying on systematic investment plans (SIPs) rather than making large, concentrated investments.

4. Large-Cap Funds:

Large-cap funds typically rely on market conditions to generate returns rather than the size of their AUM. While larger AUM might provide the benefit of liquidity and stability, it doesn't necessarily lead to higher returns. In many cases, smaller funds with lower AUMs can outperform larger ones, depending on the market and investment strategy. The performance of large-cap funds is primarily driven by the underlying market yields rather than AUM alone.

Calculation of AUM

Fund houses use various methods to calculate AUM, which is determined by three key factors: inflows, outflows, and the market price of assets. At any given time, funds experience both inflows and outflows, with the difference between them resulting in net flows. Positive net flows (inflows exceeding outflows) generally lead to an increase in AUM, although this isn't guaranteed in every case. Similarly, a rise in the market price of the underlying assets can boost AUM, but this too depends on other variables.

When both net flows and market prices are positive, AUM will grow. Conversely, if net flows are negative and market prices decline, AUM will decrease. If one factor is positive and the other is negative, the change in AUM depends on the stronger influence between the two.

AUM and Expense Ratio

When a fund house manages your investments, it charges a fee based on the amount of money under its management. This fee is a percentage of your total investment and is used to cover the operational costs of running the fund. The fee is deducted from the returns you earn and is part of the fund's Total Expense Ratio (TER).

According to SEBI regulations, larger funds are required to charge lower TERs, while smaller funds are allowed to charge higher fees to manage their costs. Below is the TER structure based on the size of a fund’s AUM:

Final Thoughts

Asset Under Management (AUM) plays a central role in understanding the scale, stability, and efficiency of a mutual fund or investment firm. Whether you’re an investor looking to evaluate a fund’s growth potential or a fund manager analysing operational costs, AUM provides valuable insights into the size and market presence of a financial institution.

For investors, AUM should not be viewed in isolation. Other factors, such as the Expense Ratio, fund performance, and Net Asset Value (NAV), must be considered to get a comprehensive picture of the fund’s effectiveness.

Ultimately, a balanced perspective is key. A fund’s AUM can be a useful tool for evaluating its health and popularity, but it’s essential to dig deeper into its investment strategy, historical returns, and risk factors before making any financial decisions.

FAQs

What does AUM stand for in the context of mutual funds?

AUM stands for Asset Under Management, indicating the total market value of all the assets a mutual fund manages on behalf of its investors.

What is the difference between AUM and NAV?

AUM refers to the total assets managed by the fund, while NAV (Net Asset Value) represents the per-unit price of the fund's assets after deducting liabilities.

Does a higher AUM mean better performance for a mutual fund?

Not necessarily. While a higher AUM indicates stability, it doesn’t guarantee better returns. In some cases, a very high AUM can dilute performance, especially in equity or small-cap funds.
