Nasdaq Composite Index
A market-capitalization weighted index of the more than 3,000 common equities listed on the Nasdaq stock exchange. The types of securities in the index include American depository receipts, common stocks, real estate investment trusts (REITs) and tracking stocks. The index includes all Nasdaq listed stocks that are not derivatives, preferred shares, funds, exchange-traded funds (ETFs) or debentures.
Investopedia Commentary
Unlike other market indexes, the Nasdaq composite is not limited to companies that have U.S. headquarters. It is very common to hear that the closing price of the Nasdaq Composite Index reported in the financial press, or as a component of the evening news.
