Robo-advisors offer investors a wide range of services and are a convenient wealth management option. Although each company provides its distinct services at varying prices, Robo-advisors’ primary goal is to provide automated investment portfolios at a low cost to investors who may not be able to invest with traditional wealth management firms.

AUM changes over time due to market fluctuations or clients’ withdrawals and is usually updated quarterly. A higher AUM does not imply that the platform has better services or performance than others; alternatively, a lower AUM does not necessarily indicate a less trustworthy Robo-advisor.

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 Robo-advisor.
