Nope can't do that. MSTR might trade at a premium to its BTC holdings but only because at the moment it allows people to buy BTC through more traditional investment accounts. Your hypothetical ABC wouldn't have any advantage over MSTR so it would trade at parity.

I'm really not trying to be pro or anti BTC/MSTR here, just explaining whats going on. It's valid to think it's stupid/overvalued, but I'm just pointing out that its P/E ratio isn't the reason. And comparing MSTR's P/E to Apple's doesn't really make sense at face value.
