The Ultimate Guide to the NASDAQ Composite Index

What Is the NASDAQ Composite?

The NASDAQ Composite is one of the most widely followed stock market indices in the United States. It tracks more than 3,000 companies listed on the NASDAQ Stock Market, primarily made up of technology, biotech, and growth-oriented firms.

Unlike the Dow Jones Industrial Average or the S&P 500, the NASDAQ Composite includes almost every stock traded on the NASDAQ exchange, making it a broad indicator of the performance of technology and growth sectors in particular.

Key Features of the NASDAQ Composite

• Market Capitalization-Weighted: Larger companies like Apple, Microsoft, and Amazon have a greater impact on the index's movements.

• Technology-Focused: While it includes a wide range of sectors, the NASDAQ Composite is heavily skewed toward tech, biotech, and innovation-based companies.

• Global Reach: Includes U.S. and international companies, offering a broader perspective on global innovation trends.
