Buffet's success doesn't just lie in mathematical models.

"Buffettology" by Mary Buffet.

In my opinion, the secret of Buffet's success doesn't just lie in mathematical models.

The secret also lies in his ability to identify businesses that have exceptionally strong positions in their respective industries and geographies.

The biggest advantage of choosing such businesses, is that the investor can afford to go wrong on growth projections.

Coca Cola is no different.

You can make a better tasting product, but it is very difficult to create a brand like Coca Cola.

Not all of Buffet's picks are mega-brands, but most of them have strong positions in their respective industries.
