What Is an Investment Adviser?

An investment adviser is a person or firm that provides advice about securities for compensation. In the United States, investment advisers are generally registered with either the SEC or a state securities regulator, depending on the adviser's size and business.

The spelling matters in this legal context. Federal securities law uses adviser with an e, even though many people casually write advisor. The core idea is compensation for advice about securities, not just general financial education or commentary.

Key Takeaways

  • An investment adviser gives advice about securities for compensation.
  • Advisers are generally registered with the SEC or state securities authorities.
  • Form ADV and Form CRS can help investors understand an adviser's business, fees, and conflicts.
  • Investment advisers are different from brokers, although some firms offer both services.

How Investment Advisers Work

An investment adviser may manage portfolios, recommend asset allocations, select investments, provide ongoing advice, or advise clients on securities-related decisions. Some advisers work with individuals and families. Others advise funds, institutions, retirement plans, or other entities.

Advisers are commonly paid through asset-based fees, fixed fees, hourly fees, subscription fees, or other disclosed arrangements. The fee model matters because it shapes incentives. An asset-based adviser may be paid more as assets under management grow, while a flat-fee adviser may separate compensation from account size.

How to Evaluate the Relationship

The most useful documents are usually Form ADV and Form CRS. Form ADV explains the adviser's business, services, fees, conflicts, disciplinary history, and practices in more detail. Form CRS gives retail investors a shorter relationship summary.

Question

Why It Matters

Are you registered with the SEC or a state regulator?

Confirms regulatory status.

How are you paid?

Reveals incentives and cost structure.

Do you custody client assets?

Clarifies asset-safekeeping arrangements.

What conflicts do you have?

Shows where compensation or affiliations may influence advice.

What services are included?

Separates investment management from broader planning or tax coordination.

Adviser Versus Broker

An investment adviser and a broker can both work with investments, but they are not the same role. Advisers are generally paid for advice and ongoing management. Brokers are generally associated with securities transactions and brokerage services. Some firms are dual registrants, meaning they offer both advisory and brokerage relationships.

That distinction affects fees, obligations, disclosures, and the questions an investor should ask. The title on a business card is less important than the legal capacity in which the person is acting for a specific account or recommendation.

The Bottom Line

An investment adviser is paid to provide securities advice and is generally registered with the SEC or a state regulator. Before hiring one, review Form ADV, Form CRS, IAPD, fees, conflicts, custody practices, and the exact services included in the relationship.
