How about the "E" in non dividend stocks? How does owning 1% of Amazon entitle me to 1% of their earnings?
The consensus is that P/E is not a good valuation metric for high growth companies.
I would rather use comparable multiples, DCF or sum of the parts for this type of exercise.
The principle being that you will benefit from stock appreciation rather than dividend payout.
