If you consider it to be true that Fairfax did undergo a transformation between 2017-2020 (with all the positives coming with it, as laid out on this board) and if you believe in the mantra that prices follow earnings you will end up with a higher share price. The buybacks, if continued meaningfully as announced a few years back by Prem, accelerate the arithmetical process of increasing EPS.
To my mind the groundworks now are more in place for an increase in share price compared to all periods before (as described in "The Fairfax Way"). This of course does not include unexpected push backs such as CAT-events and so forth.
