Nasdaq Composite Index is a stock market index out of more than 2,500 U.S. and non-U.S. technology and growth companies listed on the NASDAQ stock market.
The Nasdaq Composite Index is a stock market index of the common stocks and similar securities (e.g. ADRs, tracking stocks, limited partnership interests) listed on the NASDAQ stock market, meaning that it has over 2,500 components. It is highly followed in the U.S. as an indicator of the performance of stocks of technology companies and growth companies. Since both U.S. and non-U.S. companies are listed on the NASDAQ stock market, the index is not exclusively a U.S. index.
Calculation Of Index
The NASDAQ Composite Index is a market capitalization-weighted index. The value of the Index equals the aggregate value of the Index share weights, also known as the Index Shares, of each of the Index Securities multiplied by each such security's Last Sale and divided by the divisor of the Index.
Two versions of the Index are calculated - a price return index and a total return index. The price return index (NASDAQ: COMP) is ordinarily calculated without regard to cash dividends on Index Securities. The total return index (NASDAQ: XCMP) reinvests cash dividends on the ex-date. Both Indexes ordinarily reinvest extraordinary cash distributions. The total return index was synchronized to the value of the price return index at the close on September 24, 2003.
The Index is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing value of the Nasdaq Composite Index may change up until 17:15:00 ET due to corrections to the Last Sale Price of the Index Securities.
Selection Of Index Components
To be eligible for inclusion in the Nasdaq Composite Index, a security's U.S. listing must be exclusively on the NASDAQ Stock Market (unless the security was dually listed on another U.S. market prior to 2004 and has continuously maintained such listing), and have a security type of either:
American Depositary Receipts (ADRs)
Limited Partnership Interests
Real Estate Investment Trusts (REITs)
Shares of Beneficial Interest (SBIs)
Closed-end funds, convertible debentures, exchange traded funds, preferred stocks, rights, warrants, units and other derivative securities are not included. Unlike other market indexes, the Nasdaq composite is not limited to companies that have U.S. headquarters. If at any time during the year an Index Security no longer meets the Eligibility Criteria, or is otherwise determined to have become ineligible for continued inclusion in the Nasdaq Composite Index, the security is removed from the Index.
