The NYSE (New York Stock Exchange) has three main rivals: the NASDAQ (National Association of Securities Dealers Automated Quotations), AMEX (American Stock Exchange), and ASE (Alternative Securities Exchange). The NASDAQ is a global electronic marketplace for buying and selling securities, while the AMEX is the second-largest stock exchange in the United States. The ASE is a smaller stock exchange that focuses on trading small-cap stocks. All three exchanges compete with the NYSE to provide investors with the best prices and services.
