Nasdaq: Meaning, Structure, and Function

Quick Definition: Nasdaq is a global electronic stock exchange where investors buy and sell shares of companies through a fully automated trading system.

Nasdaq stands for the National Association of Securities Dealers Automated Quotations. It is a global electronic marketplace where buyers and sellers trade stocks using a fully automated system. Launched in 1971, it became the world’s first electronic stock exchange—unlike traditional floor-based exchanges, Nasdaq introduced a fully electronic trading model.

Nasdaq functions as:

• A stock exchange where companies list their shares

• A technology-focused market, hosting many high-growth businesses

• Nasdaq, Inc. also operates exchanges that facilitate trading in derivatives and other financial products
   

It is known for its electronic trading infrastructure, which is widely used by many technology-focused and growth-oriented companies.

• Fully electronic trading system

• Focus on technology and growth companies

• Home to many global large-cap tech firms

• Facilitate trading in derivatives and other financial products 

• Fast and efficient order execution
  

During the late 1990s and early 2000s, Nasdaq became closely linked with the dot-com boom. Many internet and technology companies were listed during this period, leading to rapid market growth followed by a sharp correction when the bubble burst. This era highlighted both the growth potential and volatility of technology-driven markets.

Nasdaq operates as a fully electronic exchange where trades are executed via an electronic trading infrastructure. It does not have a physical trading floor like the NYSE.

Nasdaq's trading model includes the following components:

• Market Makers – Provide liquidity by continuously quoting buy and sell prices.
  

• Electronic Communication Networks (ECNs) – Match orders automatically between buyers and sellers.
  

• Advanced Trading Systems – Ensure high-speed and efficient order execution.
  

• Listing Requirements – Companies must meet financial and regulatory standards to be listed.
   

How the Trading Process Works

1. An investor places a buy or sell order through a broker.

2. The order is sent to Nasdaq’s electronic trading system.

3. The system matches buy and sell orders using automated platforms and market participants.

4. Market makers help by providing buy and sell quotes to ensure liquidity.

5. Once matched, the trade is executed electronically once matching criteria are met.

The system ensures fast execution, tight spreads, and high transparency, making Nasdaq a preferred venue for global investors.

The Nasdaq Composite Index is one of the most widely followed stock market indices. It includes more than 3,000 common equities listed on the Nasdaq Stock Market. Listed below are some of the important features:

• It is market-capitalisation weighted, meaning large companies have greater influence.

• The index includes technology, biotech, consumer services, healthcare, and financial firms, though tech dominates.

• It is used as a benchmark for the performance of the U.S. technology sector and growth stocks.

Movements in the Nasdaq Composite often reflect investor sentiment toward innovation and the future of the digital economy.

How the Nasdaq Composite is Calculated

The Nasdaq Composite is a market-capitalisation weighted index, meaning:

• Companies with larger market value have a bigger impact on the index

• Smaller companies have a lower influence on index movement

• The index is weighted by the modified market capitalisation of its constituent securities, so changes in market value influence the index level.
