Furthermore, due to the vast number of platforms available today, determining the best online broker can be difficult.

What are assets under management (AUM)?

In general, AUM refers to the market value of assets managed by a company on behalf of its clients. This metric is used by different financial institutions such as mutual funds, hedge funds, insurance companies, and brokerage firms. It is a key performance indicator that measures the success of a firm in attracting customers and increasing its market share.

The definitions and calculations for AUM can vary by company. For example, funds deposited with the company but over which the company has no discretionary authority are typically excluded from the calculation. In this case, assets under administration are calculated, where the service provider does not have discretion over the asset allocation decisions and the clients manage their funds directly. In this study, we listed the brokers with data related to AUM. If it was not available, we checked their clients’ assets or Assets Under Administration.

Who are the biggest brokers in the world?

As of this writing, the largest broker worldwide (in terms of number of users and AUM) is Fidelity, closely followed by Charles Schwab and Vanguard.


AUM changes over time due to market fluctuations or clients’ withdrawals, and it is usually updated on a quarterly basis. A higher AUM does not imply that the broker has better services than others, or alternatively, a lower AUM does not necessarily indicate a less trustworthy broker. 

Each broker has its own unique features that differentiate it from its competitors, such as fees, minimum balance requirements, or trading platform. Still, not all customers are eligible to open an account at one of the above-mentioned brokers since some brokers limit their services to particular regions. We encourage investors to check the company’s financial statements and website, and do their due diligence about the services and opportunities before opening an account with any broker.
