The Motley Fool is not known for their quantitative models. They are known for a discretionary growth style of investing that attempts to identify game changing companies and then holds them for the long-term, seeking to generate returns that are multiples of their original investment. 
But despite their discretionary nature, their book The Motley Fool Investment Guide did contain a detailed quantitative model to select small-cap growth stocks. When we launched Validea in 2003, we wouldn't have guessed that this model would have outperformed all the other models we launched, but it has produced the best return of all the models we follow in the 18 years since. 
In this episode, we take a look at the model we extracted from the Motley Fool Investment Guide and the criteria it uses to select small-cap growth stocks.
