Sure, the business he's built is an incredibly successful fund. From IEP's quarterly results: >An investment in IEP stock made at the beginning of 2000 has increased by approximately 1,500%, or an average annual return of 22%, through October 31, 2013. But perhaps more compelling is that since April 1, 2009, when the economic recovery started: 1) an investment in IEP stock resulted in a total return of 347%, or an average annual return of 39%, through October 31, 2013, and 2) IEP’s indicative net asset value has increased during this period by 282%, or an average annual return of 35%, through September 30, 2013. Or is that not a real business in your eyes?
