Types of Markets

Securities markets are organized into four categories based on how and where securities are traded. Here is the big-picture framework you need for the exam.


The Four Market Categories

MarketWhat HappensWho TradesWhere
PrimaryNew securities are issued and sold for the first timeIssuers sell to investors (via underwriters)Through the offering process (not on an exchange)
SecondaryPreviously issued securities trade between investorsInvestors buy from and sell to other investorsExchanges (NYSE), OTC markets, electronic networks
ThirdExchange-listed securities are traded OTCInstitutional investors, non-exchange member dealersOver-the-counter (off-exchange)
FourthSecurities trade directly between institutionsLarge institutional investorsElectronic Communication Networks (ECNs); no broker-dealer intermediary

Exam Tip: Gotchas

  • Primary market = issuer receives the money. Secondary market = selling investor receives the money. This is the most tested distinction.

How They Connect

Think of it this way: The four markets form a progression from creation to increasingly direct trading:

  • Primary market - Where a security is born (issued for the first time)
  • Secondary market - Where that security lives and trades after issuance
  • Third market - Exchange-listed securities trade off-exchange (still secondary market activity)
  • Fourth market - Institutions trade directly with each other, bypassing broker-dealers entirely

Exam Tip: Gotchas

  • The third and fourth markets are both subsets of secondary market activity. They involve previously issued securities changing hands. The key distinctions are where the trading happens and who is involved.
  • Third market involves exchange-listed securities traded OFF the exchange, not unlisted securities.
  • Fourth market has NO broker-dealer intermediary. Institutions trade directly via Electronic Communication Networks (ECNs).
