Techstrategy & others have made this comparison. I don't believe it. It is just a grossly overvalued security, being pumped & traded back and forth by a few institutions in an easy money environment. Below $150, it might be a buy.
I have always said I do not believe there is company fraud. So, in that sense it absolutely is NOT Enron. The issues lie in the financial services sector. I do believe that some digging there will turn up material omissions, gross negligence and FAR more. It will be the Enron in that it will be the poster child for anger against WS (and will hopefully serve as the catalyst for some real change...)
Although I don't believe AMZN is outright another Enron, I do believe there is cronyism on Wall Street, and some accounting methods that border on the unethical. There is NO explanation for slowing growth, and losing money after being in business for 19 years and the stock ripping to all time highs day after day.
Someday it will be uncovered, but it is without a doubt beyond abnormal.
