A more thorough explanation:

The New York Stock Exchange (NYSE) is a group of member firms that buy and sell securities for themselves and their clients. It is the largest stock exchange in the United States and only trades in large companies with at least one million outstanding shares.

For example, companies like Apple, Coca-Cola, and General Electric are listed on the NYSE. These companies have millions of shares available for trading, and investors can buy or sell these shares through the NYSE.

The NYSE is important because it provides a platform for companies to raise capital by selling shares to investors. It also allows investors to buy and sell shares easily, which helps to determine the value of a company's stock.
