Cramer said Apple was able to beat Wall Street expectations when it reported last week. Yes, iPhone sales came in a bit light, but the company delivered on profits and sold more iPads than expected. The result? A 12.4% haircut in the stock on a single day. Compare that to Amazon, which missed earnings by 6 cents a share and fell short on revenue by $1.3 billion. Wall Street's response? Send shares up a cool 10% in after-hours trading. Amazon trades at 68 times earnings, Cramer reminded viewers, Apple just nine times earnings, and that's not even counting the $137 billion in cash. Are these valuations ridiculous? Absolutely. But do they make sense to Wall Street? You bet. Cramer explained that Apple has lost its aura of growth, which means it's now being treated like any other stock. Analysts are asking questions and are demanding answers. Meanwhile, Amazon still has its growth, which means it can provide foggy guidance, or almost no guidance at all, and analysts will look the other way. How many Kindles did Amazon sell? No one knows. By how much is the eBook business growing? Guess. Meanwhile, Apple must provide iPhone and iPad sales to the letter and even that is not enough. Cramer said Amazon has no competition, which means it only needs to stop investing in its business to make money. The company also still has its visionary founder, Jeff Bezos. But Apple has competitors, some would argue good ones, which means it's being held to different standards. Is the market fair? Decidedly not, Cramer said. But once investors realize the rules of the game, Wall Street can begin to make a little sense.
