What Do You Know About Investing Today?

Barry Rittolts: What do you know about the world of investing today that you wish you knew 50 years or so ago when you were first getting started? The great companies that you invest in you should hold. John Mack: My son, 11 years old, Morgan Stanley takes Apple public. He says, Dad, this is a great company. I want to buy stock in it. And he's like 11 or 12 years old. And he buys shares in it. It's just been a home run.
