The NASDAQ stock exchange is one of the most prominent electronic trading platforms in the world. Synonyms for the term "NASDAQ" may include the following: the National Association of Securities Dealers Automated Quotations; the NASD; the tech-heavy NASDAQ Composite; the NASDAQ 100; and the NASDAQ-OMX Group. These terms are occasional used interchangeably to refer to the broader entity that comprises the NASDAQ equity markets. Several new acronyms and tags have also emerged recently, including the IXIC or NASDAQ Composite Index, which is a market capitalization-weighted index of over 2,500 publicly traded companies. Regardless of the terminology used, the NASDAQ remains a crucial indicator of investor sentiment towards technology stocks and emerging businesses.
