The NASDAQ is the second-largest stock exchange in the US, with half of all public limited companies listed.

    It is also second-largest stock exchange in the world after the NYSE when it comes to the ]market capitalisation of its listed companies and it has the highest trading volume of all electronic stock exchanges in the world.

    The name is an acronym for the National Association of Securities Dealers Automated Quotations.

    The usual opening hours are from 14.30 to 21.00 GMT. Like many electronic trading platforms, the NASDAQ also features extended trading hours, during which time the volume is relatively low.

    The NASDAQ publishes and maintains three indices: NASDAQ Composite (most commonly cited), NASDAQ-100 and NASDAQ Biotechnology.

    The exchange was founded in 1971 by the National Association of Dealers and is situated on Times Square in New York. It is operated by the NASDAQ OMX Group Inc. and regulated and controlled by the United States Securities and Exchange Commission (SEC).
