I think it is time for investors to view the growing pessimism as a sign the company's investments might take a bit longer to produce the bottom-line growth for which investors are hoping. Likewise, it's never a welcome sign that stocks are able to grow in the face of decreasing estimates. In fact, the opposite tends to occur. So essentially, investors still placing bets on Amazon today are assuming the company can continue to defy both gravity and logic at the same time. The odds are not in its favor.
