A closer at NASDAQ

Founded in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an American stock exchange, and its currently the second largest stock exchange in the world, just behind the largest NYSE. In addition to being the second largest stock market in the financial industry, NASDAQ also owns the NASDAQ Nordic, NASDAQ Baltic stock market network and several others US stock exchanges.

NASDAQ, which stands for National Association of Securities Dealers Automated Quotations, was the world’s first electronic stock market when it started trading on 1971. At that time, the stock trading platform was merely a quotation system and did not provide any means of electronic trading.
