Imagine being able to invest your money in some of the most solid and recognized companies in the world, without having to buy individual shares or worry about closely following every market movement. This is precisely what the S&P 500 index allows you to do. It is a set that brings together five hundred of the most influential companies listed on the most important stock exchanges in the United States, such as the New York Stock Exchange and the Nasdaq. It is a fairly representative reflection of the health and evolution of the U.S. economy.
