NASDAQ-100
Résumé
The Nasdaq-100 (^NDX) is a stock market index made up of 101 equity securities issued by 100 of the largest non-financial companies listed on the Nasdaq stock exchange. It is a modified capitalization-weighted index. The stocks' weights in the index are based on their market capitalizations, with certain rules capping the influence of the largest components. It is limited to companies from a single exchange, and it does not have any financial companies. The financial companies are in a separate index, the Nasdaq Financial-100.
The Nasdaq-100 was launched on January 31, 1985 by the Nasdaq. It created two indices: the Nasdaq-100, which consists of Industrial, Technology, Retail, Telecommunication, Biotechnology, Health Care, Transportation, Media and Service companies, and the Nasdaq Financial-100, which consists of banking companies, insurance firms, brokerage firms, and Mortgage loan companies.
The base price of the index was initially set at 250, but when it closed near 800 on December 31, 1993, the base was reset at 125 the following trading day, leaving the halved Nasdaq-100 price below that of the more commonly known Nasdaq Composite. The first annual adjustments were made in 1993 in advance of options on the index that would trade at the Chicago Board Options Exchange in 1994. Foreign companies were first admitted to the Nasdaq-100 in January 1998, but had higher standards to meet before they could be added. Those standards were relaxed in 2002, while standards for domestic firms were raised, ensuring that all companies met the same standards.
The Invesco QQQ, an exchange-traded fund sponsored and overseen since March 21, 2007 by Invesco, trades under the ticker . It is nicknamed “triple Qs” or “cubes”. It was formerly called Nasdaq-100 Trust Series 1. On December 1, 2004, it was moved from the American Stock Exchange, where it had the symbol QQQ, to the Nasdaq, and given the new ticker symbol QQQQ, sometimes called the "quad Qs" by traders. On March 23, 2011, Nasdaq changed its symbol back to QQQ.
