Ha, I have a mate who's wife calls him the energiser bunny, and he is one of the most successful guys ( personally, professionally and financially) I know.

It's actually quite simple.

Yes, the SP stinks to high hell.... but BRK are getting better at what they are doing, the effect of which increases their asset base. That asset base, all or part of will be monetised sooner rather than later ( 2023) and that event will crystallise the value held by that asset base ( at a 20-30% discount to NPV which is a significant multiple of the current SP), most of which will end up in the bank accounts of shareholders.

I promise I won't post " I told you so" when it happens.
