What Is the NYSE

NYSE in Finance

The NYSE was founded in 1792 when 24 stock brokers from New York City signed the Buttonwood Agreement at 68 Wall Street.

Given its age, many of the oldest publicly traded US companies are listed in the NYSE.

At its inception, the NYSE only traded 5 securities: three government bonds and two bank stocks.

Today, about 3.5 billion shares are traded on the NYSE daily, for a total market cap of over $28 trillion.

NYSE Corporation

For most of its existence the NYSE has been run as a private organization.

However, it became public in 2005 following the acquisition of Archipelago, an electronic trading exchange.

In 2007, the NYSE entered a merger with Euronext, the largest stock exchange in Europe, to create NYSE Euronext.

It was acquired in 2013 by Intercontinental Exchange, which is currently the parent company of the NYSE.
