Very exciting discussion between @Viking and @Munger_Disciple. Thank you!
Maybe some thoughts on this: In the end, Munger's approach reminds me a bit of the early Buffett of Cigar Butt Investments. Of course not really, because Munger is also interested in the PE ratios and not the liquidation value; but Munger just insists on a very cautious assessment of the earnings, also sees no moat, and thus consequently focuses very strongly on the "margin of safety"; and especially this point reminds me of Cigar Butt.
Viking, on the other hand, I often understand to mean that with the many in-depth analyses of the individual parts and the many changes in perspective, he ends up - in my perception - shedding much more light on management and its capabilities, and thus, in my view, the overall picture evolves of a value-oriented company that has become increasingly well-managed over the years and that uses "float" as leverage. Whereas decades ago, CRs were regularly extremely poor relative to the market, Fairfax has averaged a few percentage points better than the market over the past decade. Thus, Prem is following much more closely in the footsteps of a Buffett or Gayner at this point. Fairfax has had by far the strongest premium growth of the top 25 insurers over the past three years. Many investments in India, Greece and the U.S. have paid off or are performing well right now. And so on. And then Viking also builds in a Margin of Safety (one that I personally think is sufficient and reasonable!), but just less conservative than Munger. So the picture that emerges is one of many positive individual decisions that form an overall picture of how Fairfax has changed after 2016. Viking's number analyses are important, but a second layer (management, moat) is forming, and I personally read a strong case for management and the presence of a moat above all else from the mosaic of many individual analyses. And at the end Viking also builds in a Margin of Safety, but to show a possible, conservatively realistic compounding perspective it is lower than Munger's. Both seem perfectly legitimate and consistent to me. They are just completely different methods.
Gayner explained in a podcast some time ago ("the evolution of a value investor") that he now pays much more attention to the development of a company than to its current state. In a sense, he said he is much more interested in the corporate movie that is being created over time than a still image (or something like that). If you have a company with a moat, the best way to recognize it is in a movie, that is, in an analysis over a longer period of time in the past, than by looking at just one point in time. I was very attracted to the idea.
It is probably rare that a company can already be considered cheaply valued without a moat and it (possibly; tbd) also has a moat on top. Otherwise, there would probably not have been this exchange here. Either way, there is a lot to be said for either a good investment or even one along the lines of "Once in a Lifetime" . We will see.
