> Anyone who thinks that Amazon's P/E ratio is meaningful of anything don't understand how Amazon operates. That's not necessarily fair. To the parent's point - if investors get spooked they would bail, much quicker and harder than if traditional fundamentals were there. You can understand Amazon's strategy while being cautious about certain P/E ratios or fundamentals. The higher it gets the more future growth is priced in and if something goes wrong it could go really bad. The market believes Amazon can dominate any category. That's significant to their valuation. What if you have a failure in grocery and other categories? That peachy confidence could erode quickly.
