NYSE American, (formerly NYSE MKT, and formerly NYSE Amex) is a U.S. cash equities market for listing and trading small-cap and mid-cap growth companies. The all-electronic market, which falls under the NYSE Group of exchanges operated by parent company Intercontinental Exchange, offers electronic designated market makers for each listed company and NYSE Arca's price-time execution model. It features trading in more than 8,000 securities and incorporates a 350-microsecond delay on all orders, proprietary data feeds and outbound routing.
The exchange traces its history back to the 1840s, with the organization of a consortium of brokers (known as "curbstone brokers" because they operated in the street) who specialized in small and newly created enterprises. The curb market grew and matured, eventually adopting listing standards (and moving indoors) under the name "New York Curb Market." In 1929, its name was changed to the New York Curb Exchange and, in 1953, to the American Stock Exchange (AMEX).
In 1998, AMEX merged with NASDAQ, but in 2004 the company regained its independence.
NYSE predecessor NYSE Euronext acquired the exchange on Oct. 1, 2008. NYSE Euronext initially rebranded the exchange post-merger, calling it "NYSE Alternext U.S. LLC" but received approval from the U.S. Securities and Exchange Commission (SEC) in March of 2009 to change it back to NYSE Amex.
NYSE MKT (as AMEX) was acquired by NYSE Euronext in 2008 for $260 million to help boost its options, exchange traded funds and cash equities businesses. NYSE closed the old Amex equities trading floor and moved it to the NYSE trading floor in 2009.
NYSE American is currently a division of the Intercontinental Exchange Group Inc., which purchased the exchange as part of the NYSE Euronext acquisition in November 2013. NYSE American and its sister equity options exchange, NYSE American Options, (formerly NYSE Amex Options), along with the New York Stock Exchange, NYSE Arca, NYSE Arca Options and NYSE National all fall under ICE's securities market division called NYSE Group.
Starting in the second quarter of 2017, NYSE closed the NYSE MKT floor, and all trading on NYSE MKT, which listed and traded around 250 small-cap companies, was automated. Both names were changed to NYSE American and NYSE American Options in January 2017. NYSE American adoped a 350-microsecond delay in trading on its market to match a competing market approach from IEX.
