Types of Markets

Quick Answer

Securities markets fall into four categories: the primary market, where new securities are issued; the secondary market, where investors trade existing securities; the third market, exchange-listed securities traded over the counter; and the fourth market, direct institution-to-institution trading with no broker-dealer involved.

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).

What Should You Check on Exam Day?

  • Can you explain the key difference between the primary market and the secondary market?
  • Do you know which market, primary or secondary, gives the issuer the money?
  • Can you state why the third and fourth markets are both considered secondary market activity?
  • Do you know what makes the fourth market different from the third market?
