A split visual showing a company issuing shares on one side (primary market) and investors trading stocks on the other side (secondary market).

When people talk about “buying stocks,” they are usually referring to one part of a bigger system.

The capital market has two main segments:

  • The primary market

  • The secondary market

Understanding the difference helps you know:

  • Where your money goes

  • How companies raise capital

  • How investors make money

What Is the Primary Market? (Simple Definition)

The primary market is where new securities are created and sold to investors for the first time.

In simple terms:
It is where you buy directly from the company.

What Happens in the Primary Market

Companies use the primary market to:

  • Raise money from investors

  • Fund expansion and growth

Common Primary Market Activities

1. Initial Public Offerings (IPOs)

An IPO is when a company:

  • Sells shares to the public for the first time

Example:

  • A private company becomes publicly listed on the
    Nigerian Exchange Group

2. Public Offers / Rights Issues

Existing companies may:

  • Issue new shares to raise additional funds

3. Bond Issuances

Governments and companies:

  • Issue bonds to investors

For example:

  • Bonds issued by the Debt Management Office of Nigeria

Key Feature of the Primary Market

Money flows from investors → directly to the company or issuer

What Is the Secondary Market? (Simple Definition)

The secondary market is where investors buy and sell securities among themselves.

In simple terms:
It is where trading happens after the initial sale.

What Happens in the Secondary Market

  • Investors trade shares with each other
