 is just an unmanaged index. Think of it like a basket of stocks. It's 500 companies. Many of them are household names, but some of them, you know, you might be surprised. You may not be familiar with them at all. You may not have heard the name. You might not have any idea what they do. But there's a reason they're in the S&P 500 index. The powers that be, the ones that decide what stocks are going to be in the index and what stocks are not going to be in the index.
