Key Terms

assets under management financial

Assets under management (AUM) is the total value of all the investments that a financial company or fund is responsible for overseeing on behalf of its clients. It’s like a big bucket that shows how much money the firm is managing for people or organizations. A higher AUM often indicates a larger, more trusted company, and it can influence how much money they earn and the services they can offer.

assets under advisement financial

Assets under advisement are the total value of investments for which a firm provides guidance or recommendations but does not have the authority to make trades or directly manage the money. Think of it like a paid consultant who advises on what to do with a homeowner’s portfolio but leaves final decisions and day-to-day control to the homeowner; for investors this metric shows a firm's market influence and potential for future fee growth, but those assets may be less sticky than funds the firm actually manages.
