Tom Gardner: OK, I just want to put these factors together. I'm really restating what you've said.

If you're looking for the next 100-bagger today, you would be looking in a big trend that has a visionary leader, high sales growth rate, and you have connection to it as a consumer. That's not the only place to find the next 100-bagger, but those four factors would be a useful way. And maybe the fifth is that it's a relatively small company. There are visionary leaders at Google, but it's not going to be a 100-bagger over the next 10 years.

So, it's a smaller company -- let's say market cap sub-$2 billion -- visionary leader, big trend, high sales growth rate, with consumer connection to you. That would be a good way for somebody to look out for it.

David Gardner: That's not a bad template. One thing I want to point out is you've described, in many cases, just what cool businesses are. They have those things. A 100-bagger takes it from the realm of business, into investing and how you, as an investor, achieve a 100-bagger, which is what we've done in Amazon.

That's a little bit of a separate story, right? Because to get a 100-bagger ... Amazon is one of the few stocks that's actually done that, that you could have done in the last 20 years, and it took 16 years. It took watching that stock go from $3 -- our cost -- to $95, and then back to $7, and we held all the way through back to $95, and then $100, $200, $300. It took 16 years of patience in a world that is very myopic.

Tom: Six months is the average holding period.

David: A lot of people sell off in advance of bad ... worried about the next earnings. There's a whole separate story. We don't have to talk about it too much in this conversation ...

Tom: No, I like it actually. Were you worried? When it went from $95 to $7, did you second-guess yourself at any point? You had a 30-bagger as an investment, and you watched it fall.

David: To a two-bagger.

Tom: To a two-bagger. So, you still had the joy of saying, "I've doubled my money," but you watched a 90% decline and obviously, in order for a stock to decline that much, most people have sold. What is it that allowed you to hold that? What are some factors in your approach to portfolio management or individual company investment?

David: Sure, and I'm going to be quick, because we're going to run out of time, but I'll just say for now, it's mostly looking at the business, not the stock. You know that; I know I'm preaching to the choir -- although while Tom and I have kind of got it for about 20 years, I think a lot of the world doesn't think about things that way.

Every time I watch financial television -- which, by the way, I don't, really -- I'm reminded again of how people are thinking too much about stocks; wigs, wags and short-term moves, and they're not really looking at the business. While Amazon's stock dramatically declined over that, the business did not nearly.

And it's not just Amazon, obviously. I'll just throw in another example near and dear to our hearts: Netflix (NFLX -1.51%).

Netflix stock dropped from a high in 2011-ish over $300, down to $55 within about 18 months. We held all the way down and we've held all the way back -- but did the business crumble? Even at its worst Qwikster moment, I think they lost about 500,000 subscribers from maybe 24 million to 23.5 million.

If you're looking at the business and you're not seeing any kind of drama there, I think it makes it a lot easier to continue to hold 30-baggers down to two-baggers, back to 100-plus-baggers.
