If you are looking for a good long-term investment, buy a company that has the highest sales in its industry. So for home improvement, you want to own Home Depot; for fast food, McDonald's; for toothpaste, Colgate Palmolive; for payments, Visa; for smart phones, Apple; and for social media, Facebook. Once a business sells more than any other company in its industry, it becomes very difficult to compete with.
