Top Nasdaq 100 Companies by Market Cap
The Nasdaq 100 is a tech-heavy index that reflects the performance of the largest non-financial companies listed on the Nasdaq exchange. These companies are ranked by market capitalization, which is the total value of a company’s outstanding shares.
Market cap plays a critical role in determining each company’s weight in the index and its influence on the Nasdaq 100’s overall movement.
What Is Market Capitalization?
Market capitalization (or market cap) is calculated by multiplying a company’s stock price by its total number of outstanding shares.
