Last year, when Mark Hulbert released his five-year rankings of the over 200 investment newsletters services he follows in the Hulbert Financial Digest, The Motley Fool's Inside Value service sat in the top spot.

The service aims to identify businesses trading a deep discounts to their true values -- such recommendations have included Berkshire HatahwayMarkel (NYSE:MKL)Bank of America, and even non-traditional value stocks like Amazon.com.

Joe Magyer is the lead advisor of the Inside Value service. Joe recently sat down with the guys from The Motley Fool's everything-financial show, Where the Money Is, to discuss a wide range of topics. The guys discuss long-term business risks to the Berkshire Hathaway business model, the genius behind Markel, and lessons Joe has learned since moving to Australia in early 2013.

In this segment of the interview, Joe tells viewers what he thinks is the most exciting part of Markel's business.

This article represents the opinion of the writer, who may disagree with the “official” recommendation position of a Motley Fool premium advisory service. We’re motley! Questioning an investing thesis -- even one of our own -- helps us all think critically about investing and make decisions that help us become smarter, happier, and richer.
