Facebook's revenue up 35% year over year: -26% (P/E ~16)
Amazon's revenue up 15% year over year: +12% (P/E 60+)
I don't get the stock market. Facebook can simply turn on billions in revenue whenever they want still with WhatsApp, which has north of 2 billion MAU, and has not been monetized at all yet. Facebook is a reverse meme stock.
