A practical guide to assets under management: what AUM means, where to find it on a company website, how to check it with official records and how to use it wisely.

Quick answer: Assets under management (AUM) is the total market value of investments a firm manages for its clients. Most asset managers and advisers show their AUM on their company website, usually on the “About us”, “Investor relations” or fact sheet pages. To verify it, check official filings, such as Form ADV on the SEC’s Investment Adviser Public Disclosure site in the US, or annual reports for listed firms.

When you choose a fund manager or financial adviser, one of the first numbers you see is assets under management. A large AUM can signal trust and scale, while a small AUM may mean a boutique firm with more personal service.

But the figure on a company website is marketing material. It may be rounded, out of date or calculated in a different way from official filings. This guide shows you where to find AUM on a company website, how to check it and what the number really tells you.

What does assets under management mean?

Assets under management means the total value of client money a firm invests and manages on their behalf. It includes shares, bonds, funds, cash and other assets in client accounts or funds the firm runs.

  • Rises: when markets go up or new clients invest
  • Falls: when markets drop or clients withdraw money
  • Used for: measuring firm size, growth and, often, fees

Many advisers charge a fee based on AUM, often around 1% a year for smaller accounts, falling for larger ones. That is why AUM directly affects a firm’s revenue.

Where can you find AUM on a company website?

1. About us page

Most firms list a headline figure, such as “$45 billion under management”, with an “as of” date.

2. Investor relations

Listed asset managers publish AUM in quarterly results, press releases and annual reports.

3. Fund fact sheets

Each fund page shows the fund size, which is that fund’s share of the firm’s AUM.

4. Regulatory or legal pages

Some advisers link to their Form ADV brochure or other disclosures in the footer.

5. Press and news

Firms often announce milestones, such as crossing $1 billion in AUM.

Example 1: Reading a website claim
A wealth firm’s homepage says “over $2 billion managed for families”. The footer links to its Form ADV, where regulatory AUM is shown as $1.84 billion as of last December. The website figure includes some advisory assets the firm does not directly manage, which explains the gap.

How do you verify a company’s assets under management?

  1. In the US, search the firm on the SEC’s Investment Adviser Public Disclosure site. Form ADV Part 1A, Item 5, shows regulatory assets under management.
  2. For listed firms, read the latest quarterly results or annual report on the investor relations page.
  3. In the UK, check the firm is authorised on the FCA Financial Services Register. The register confirms permissions but does not list AUM, so use the firm’s annual report or fund documents.
  4. Check the date of every figure. AUM can change a lot in one quarter.
  5. Compare the website number with the filing. Small differences are normal; big unexplained gaps are a warning sign.

Always make sure you are on the firm’s real website. Fake “clone firm” sites copy real names to trick investors.

AUM vs other measures

Term Meaning Where you see it
Assets under management (AUM) Money the firm actively manages and makes decisions on Websites, filings, results
Regulatory AUM (RAUM) AUM calculated under SEC Form ADV rules Form ADV
Assets under administration (AUA) Assets the firm holds or services but does not manage Platforms, custodians
Assets under advisement Assets the firm advises on but clients decide Consultants
Fund size / net assets Value of a single fund Fact sheets

Be careful when comparing firms. One may quote AUM while another quotes total client assets, which can look much bigger.

What does a company’s AUM tell you?

  • Scale: big firms can spread costs and invest in research and technology
  • Trust: a long record of growing AUM suggests clients stay
  • Stability: firms with steady AUM are less likely to close funds
  • Fee power: larger firms often offer lower fees on big accounts

But AUM is not a measure of skill. A huge firm can perform badly, and a small boutique can perform very well. Look at fees, long-term results, strategy and service too. Our guide to value investing explains how to judge investments on their merits.

Example 2: Choosing between two advisers
Adviser A manages $8 billion and charges 1.2%. Adviser B manages $400 million and charges 0.8% with a dedicated planner. Both have similar results. For a $300,000 account, Adviser B saves $1,200 a year and gives more personal service, so AUM size alone is not the deciding factor.

Why does a company’s AUM change?

AUM moves for two main reasons: market performance and net flows. If markets rise 10%, a firm’s AUM rises even if no new client joins. If clients withdraw money, AUM falls even in a good market.

  • Market moves: share and bond prices change the value of client portfolios every day
  • Net inflows: new clients and extra deposits add to AUM
  • Outflows: withdrawals, closed accounts and lost mandates reduce it
  • Acquisitions: buying another firm can add billions overnight
  • Currency: for global firms, exchange rates change the reported figure

When a firm reports growth, check whether it came from new money or just rising markets.

Which companies have the largest assets under management?

The world’s largest asset managers each look after trillions of dollars. BlackRock, Vanguard, Fidelity, State Street and others regularly appear at the top. BlackRock reports AUM of more than $10 trillion on its investor relations pages.

The exact ranking changes each quarter with markets and fund flows, so check each firm’s latest results for current numbers. Industry rankings from groups such as the Thinking Ahead Institute are also published yearly.

Tips for using AUM wisely

  1. Always note the “as of” date beside any AUM figure.
  2. Check whether the number is AUM, AUA or total client assets.
  3. Verify with official filings before you invest.
  4. Look at AUM trends over several years, not one figure.
  5. Ask how fees are linked to AUM and whether they fall as your balance grows.

BTS Magazine Tip
Take a screenshot of the AUM claim on a firm’s website with the date. If you later see a very different number in filings, you can ask the firm to explain the difference.

Pick one fund manager or adviser you are considering. Find the AUM on its company website, then search the firm on the SEC adviser site or its annual report and compare the two figures and dates.
