They don't talk about it because they don't want you to know
I don't discount that AMZN is a good company, but its valuation is beyond my understanding. First, I don't believe AMZN's competitors will just sit still and waiting for AMZN to continue take their market shares. Second, many states will start collect sale tax, although there is lack of discussion about this crucial piece of information and many analysts just ignore about it altogether because they all know that this is not good for AMZN. Sale tax will hinder AMZN's ability to sell and revenues. Lastly, because of not believing in AMZN's valuation, I have paid dearly, but I will see this to the end. I will see this stock to below $200.
