The New York Stock Exchange

The New York Stock Exchange (NYSE), the oldest and most prestigious stock exchange in the world, is also known as Wall Street because it is located at Wall Street in New York City. You often see it on TV, a gigantic floor with computer monitors and busy people running around, waving their hands, and writing in notebooks. The NYSE is a matchmaking place for stock transactions. The people running on the exchange floor are the matchmakers and are called specialists. They are the ones who execute your buy or sell orders on the exchange floor. Most established companies list their stock in the NYSE. IBM, GE, GM, and AT&T are just a few.
