@Viking Thanks for very insightful analysis.
While I agree with all of your points, I think the CAGR since inception is misleading metric to look at.
What do I mean? If we remove the first 5, 10, 15 years, it is very clear that the numbers don't look stellar but rather average. The low starting point gives a high boost, but once we normalize it, the numbers look average.
For example, the float/share since 1985 grew at 18.4% compounded, the growth rate reduces dramatically once we exclude the initial years. The float/share since 1995 grew at 11.4%, and since 2000 grew at just 5.5%.
Disclosure: I have 35% of my portfolio in Fairfax, and 15% in Fairfax India.
