> Amazons market cap is $475B. Assuming 10% ROI and 3% profit margin, Amazon must make $16 trillion in revenue some time in the future to justify the current price.
3% of $16 trillion is $480 billion dollars. At a price-earnings multiple of say 10 the market cap would be $4.8 trillion. If $475 billion grows at 10% per year then it will take 24 years to grow to $4.8 trillion.
In 24 years total global retail sales might grow from $22 trillion to say $160 trillion. Is it so unreasonable to think that Amazon might have a 10% share of total retail sales in 24 years?
