Foolish investors know that the best way to invest is to take the long-term approach. Find excellent businesses that you can understand, buy their stocks when the price is fair, and then hold them for long periods of time. And that's the operative word: time. The longer you can hold shares of great businesses, the more time they'll have time to compound and grow. And time is why Motley Fool One analyst Jason Moser introduced his daughters Hannah and Ainsley to investing at such a young age. Now at ages eight and seven (OK, Hannah's birthday is just a couple of weeks away and she'll be nine), they own shares of six different companies, and their portfolio is handily beating the market with a total return of 36% since they started! In this video, Jason and his daughters talk about their two most recent purchases, as well as a couple of other stocks that they think they might like to own one day.
