What Happened to the FedEx of India?

In a portfolio of 14 stocks in 1995, I had four out of the 14 that all eventually went up more than 50 times. In one of them, I had a 10% position, which completely altered my net worth. And so I started thinking how often has this happened in my portfolio? How often has it happened where we've had these companies where I was smart enough to buy them, but not smart enough to hold them? And why is that happening? So what I, which is the subject of the talk today, the framework, what I did is the best way to learn is to teach.
