- Assets under management (AUM)
- Related: Management fee, Institutional investor
The total market value of all investments a firm manages on behalf of clients. It measures the size and reach of an asset manager and drives fee revenue, since most management fees are charged as a percentage of this value.
- Institutional investor

An individual who invests personal savings rather than money pooled from an organization. Retail investors usually invest smaller amounts, pay published fees, and are often protected by specific disclosure and suitability rules.

The process by which buyers and sellers interact to establish a market price reflecting available information. Active trading and competition among participants make this process more efficient.
