Quick Scoop

Nasdaq is a major U.S. stock exchange, and people often also use “the Nasdaq” to mean its stock-market index. It is especially known for listing many technology and growth companies, and it operates as an electronic marketplace rather than a traditional trading floor.

What it is

• Stock exchange: A place where investors buy and sell shares of public companies.

• Electronic market: It was the first fully electronic stock market, which helped modernize trading.

• Second-largest exchange: It is the second-largest stock exchange in the world by market capitalization.

Nasdaq as an index

• Nasdaq Composite: This is the index many people mean when they say “the Nasdaq.” It includes thousands of stocks listed on the exchange.

• Tech-heavy: It is known for its heavy concentration of technology companies, though it includes businesses from other sectors too.

Why it matters

• It is a key benchmark for U.S. tech and growth stocks.

• Big companies like Apple, Microsoft, Amazon, and Nvidia are commonly associated with the exchange because they are listed there.

Simple example

If someone says, “The Nasdaq is up today,” they usually mean the Nasdaq Composite index rose. If they say a company is “listed on Nasdaq,” they mean its shares trade on the Nasdaq stock exchange.

Bottom line: Nasdaq is both a stock exchange and, in common conversation, a stock index tied closely to technology and growth companies.
