A company already listed on the NYSE wants to list on the AMEX as well. What stands in its way?

1. The American Stock Exchange is another national stock exchange, listing the securities of more than 700 corporations. 2. It handles only 4 percent of the annual share volume traded on U.S. securities exchanges. 3. Its rules are less strict than those of the NYSE, so most AMEX firms are smaller and less well known. 4. Companies cannot be listed on both exchanges at the same time, so some move up to the NYSE once they qualify while others stay put. 5. The AMEX has become a major market for exchange-traded funds and in options trading. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 16 "Understanding Financial Management and Securities Markets", section 16.7 Buying and Selling at Securities Exchanges_
