Market Makers and Associated Persons

With the definitions of broker-dealers and underwriters established, let's look at two more key roles within the broker-dealer ecosystem: market makers who provide liquidity and associated persons who are connected to broker-dealer firms.


Market Maker

A market maker is a dealer that holds itself out as ready to buy and sell a particular security on a continuous basis at publicly quoted prices.

  • Must maintain a two-sided market - quoting both a bid price (willing to buy) and an ask price (willing to sell) simultaneously during exchange hours
  • Provides liquidity - ensures that investors can always find a counterparty for their trades
  • Profits from the spread - the difference between the bid (lower) and ask (higher) prices
  • Obligated to buy and sell at their displayed prices

Market presenceContinuous during exchange hoursAs needed

Exam Tip: Gotchas

  • A market maker is a type of dealer, but not all dealers are market makers. The distinguishing feature is the obligation to maintain a continuous two-sided market (both bid and ask) at publicly quoted prices.
  • A dealer only willing to sell is not a market maker. Market makers must quote both a bid AND an ask (two-sided market).

Associated Person

An associated person of a broker-dealer is broadly defined under the Securities Exchange Act of 1934, Section 3, to include:

  • Any partner, officer, director, or employee of a broker-dealer
  • Any person controlling, controlled by, or under common control with the broker-dealer

Who is excluded?

  • Clerical and administrative staff are excluded from the definition of associated person
  • These individuals do not effect securities transactions or make investment decisions, so they fall outside the regulatory scope

Exam Tip: Gotchas

  • Clerical staff are NOT associated persons. The receptionist and file clerk at a broker-dealer are excluded from the definition because they do not effect transactions or make investment decisions.

Associated Person vs. Agent

This is a key distinction for the exam:

  • Associated person (broad): Anyone connected to the broker-dealer (BD), including partners, officers, directors, employees, and control persons
  • Agent (narrow): An individual who actually effects securities transactions on behalf of a BD or issuer
  • Every agent is an associated person, but not every associated person is an agent
  • A compliance officer, for example, is an associated person but is not an agent (does not effect transactions)
  • An associated person who effects securities transactions must register as an agent

Exam Tip: Gotchas

  • "Associated person" and "agent" are not interchangeable. Associated person is the broader category (anyone connected to the broker-dealer); agent is narrower (only individuals who effect transactions).
