TheStreet's Jim Cramer is keeping an eye on Apple (AAPL) Tuesday when the tech giant reports its fourth quarter earnings results after the market close. Cramer says there's a belief that Apple's iPhone sales have suddenly decelerated but he says he's not sure about that. He says, 'I'm sticking by my own Apple, don't sell Apple, I see the pressure in it like everybody else.' Cramer says while he understand investors wanting to sell ahead of earnings, it's not his strategy. He says, 'I think it's a company that's returning a lot of capital with much in the pipe but short-term obviously people are bolting from Apple.' Analysts polled by Reuters are expecting the company to post earnings of $1.88 a share on $51.1 billion in revenue for the quarter. Shares of Apple are up about 5 percent year-to-date.
