While I won't argue that the business will not grow / contract in the future, because it likely will - what is concerning is the equity investment strategy over the past 10 years has been a disaster, select large portfolio holdings are homerun swings without a clear strategy, and the forward equity strategy is a mixed bag of investments without any clear investor advantage other than, it's cheap.
The age old strategy is to be the best at your part of the world. I personally am guilty (perhaps very guilty) of thinking that my investable universe is larger than it should be. In my opinion Fairfax could do with an overhaul (read: narrowing) of how they deploy equity capital - as it's possible to buy "cheap" assets in any market, in any vertical - with patience and best in class platform / skills for the niche.
As my underwriting box thankfully narrows over time - Fairfax falls outside my criteria, and I'll be peeling off my 10+ year holdings over time, with remorse.
