logic would have said buy AAPL sell AMZN because strong profits aapl loss amzn lots of money in the bank aapl having to borrow money amzn. Internet sales tax coming for large internet companys that favor small internet sellers.
AMZN stock is example of why you don't short because you think it's overvalued: that's an old story that started long long ago: heck, since 2008, the low PE was found right near the low of the stock in 2008: now the stock is going up and couldn't give a rat's buttt about what the PE is: just the support of $'s coming in. That's what drives AMZN stock: picking the top of it has been the ultimate fools game. Obviously, it has greateer support than AAPL stocks as AAPL cracked while AMZN is making new alltime highs. That's a fact not a point of view.
