The Nasdaq Composite measures the change in more than 3,000 stocks traded on Nasdaq. The Nasdaq Composite is often referred to as the “Nasdaq” and is an index commonly cited by financial journalists and reporters.

Types of securities in the index include:

  • American Certificate of Trust – ADR
  • Common shares
  • The interest rate on capital contribution with limited liability
  • Ordinary shares
  • Real Estate Investment Trusts (REITs)
  • Shares of interest of SBI holders)
  • Tracking Stocks

The index includes all Nasdaq-listed stocks but does not include derivatives, preferred stocks, funds, exchange-traded funds (ETFs), or debt securities.

The Nasdaq 100 measures the 100 largest non-financial companies by market value listed on the Nasdaq exchange. These companies operate across various sectors, although the largest are often technology-related. Each year, companies can be added or removed from the Nasdaq 100, depending on their market value.
