It is not ridiculous. It took Amazon 7 years to turn a profit. CAGR is just getting started. They're moving forward aggressively and guess what? It takes money to make money. Economics 101.
Please show us where CAGR "advertised" a 300% profit margin. I don't believe I have ever seen that. Thanks in advance.
Maybe you are mixed up with the 300%+ gain investors enjoyed not so long ago.
