Market Participants and Their Roles

With the regulatory framework in place (the SEC at the top, self-regulatory organizations (SROs) enforcing rules, and the Securities Investor Protection Corporation (SIPC) backing customers), you can now understand the participants who operate within this structure.


Investor Types

TypeDefinitionKey Facts
Retail investorsIndividual, non-professional investorsReceive the most regulatory protections
Institutional investorsLarge entities (pension funds, mutual funds, insurance companies, banks)Trade in larger volumes; may receive fewer disclosure protections due to their sophistication
Accredited investorsMeet specific financial thresholds per SEC Rule 501(a) of Regulation DCan participate in private placements and other exempt offerings

Accredited investor thresholds:

  • Net worth: Over $1 million (excluding primary residence), individually or jointly with a spouse
  • Income: Over $200,000 individually (or $300,000 jointly with a spouse) in each of the last two years, with a reasonable expectation of the same in the current year
  • Certain professional certifications (Series 7, Series 65, Series 82) also qualify an individual

Exam Tip: Gotchas

  • Accredited investor net worth excludes the primary residence. Questions often include home equity in the net worth calculation to see if you subtract it.

Broker-Dealers

A firm registered as a broker-dealer can act in two distinct capacities:

CapacityRoleCompensationActing As
BrokerExecutes trades on behalf of customersCommissionAgent
DealerTrades for its own accountMarkup (buying from dealer) or markdown (selling to dealer)Principal
  • Most firms are registered as both broker and dealer
  • Must register with the SEC under Section 15 of the Securities Exchange Act of 1934 and become members of the Financial Industry Regulatory Authority (FINRA)

Exam Tip: Gotchas

  • Broker = agent = commission. Dealer = principal = markup/markdown. On the SIE, watch for questions that describe the compensation type and ask you to identify the capacity. If the firm earned a commission, it acted as agent (broker). If it earned a markup, it acted as principal (dealer).

Types of Broker-Dealers

TypeFunction
Introducing brokerTakes customer orders but does not hold customer funds or securities; clears through another firm
Clearing brokerHolds customer assets, executes settlements, and provides back-office functions
Prime brokerProvides specialized services to hedge funds and institutional clients (lending, custody, clearing)

Exam Tip: Gotchas

  • An introducing broker does not hold customer funds. It routes orders through a clearing broker, which handles custody and settlement.

Other Key Market Participants

Investment Advisers

  • Provide investment advice for compensation
  • Must register with the SEC (if managing $100 million or more in assets) or the state (if below that threshold)
  • Owe a fiduciary duty to clients: must act in the client's best interest

Exam Tip: Gotchas

  • Investment advisers owe a fiduciary duty; broker-dealers are held to a suitability standard (Reg BI). Do not confuse the two. Fiduciary = must put the client's interest first. Suitability = recommendation must be appropriate, but does not require the best option.

Issuers

  • Entities (corporations, municipalities, governments) that create and sell securities to raise capital
  • An issuer brings new securities to the market through an offering

Underwriters

  • Investment banks that help issuers bring securities to market
  • Buy securities from the issuer and resell them to the public
  • Per FINRA Rule 2269, broker-dealers must disclose their participation or interest in a primary or secondary distribution
  • Per FINRA Rule 5250, payments for market making are prohibited

Municipal Advisors

  • Advise state and local governments on municipal bond issuances and financial products
  • Regulated by the Municipal Securities Rulemaking Board (MSRB) (rulemaking) and the SEC (enforcement)

Traders and Market Makers

  • Market makers are dealers that stand ready to buy and sell specific securities at all times
  • They provide liquidity by maintaining a two-sided market (both a bid price and an ask price)
  • Market makers profit from the spread between the bid and ask prices

Custodians and Trustees

  • Custodians hold and safeguard financial assets on behalf of clients
  • Trustees have a fiduciary responsibility to act in the beneficiary's interest

Transfer Agents

  • Maintain records of securities ownership
  • Process ownership transfers between buyers and sellers
  • Issue and cancel certificates
  • Distribute dividends to shareholders

Market Infrastructure

Depositories and Clearing Corporations

EntityFull NameRole
DTCCDepository Trust & Clearing CorporationProvides clearing, settlement, and information services for equities, bonds, and mutual funds
OCCOptions Clearing CorporationCentral clearinghouse for all listed options; guarantees performance of options contracts
  • The DTCC was formed in 1999 from the merger of the Depository Trust Company (DTC) and the National Securities Clearing Corporation (NSCC)
  • The DTCC settles the vast majority of securities transactions in the United States
  • The OCC acts as a central counterparty: it stands between the buyer and seller of every options contract, guaranteeing that the contract will be fulfilled

Exam Tip: Gotchas

  • The OCC guarantees options contracts, not equity trades. The DTCC handles clearing and settlement for equities, bonds, and mutual funds.
  • The DTCC was formed from the merger of the DTC and NSCC. Questions may reference these predecessor organizations.
