What does Apple have in store in months ahead?

Apple's earnings report this week will draw the usual scrutiny of investors, but they may already be looking ahead to what the iPhone and Mac maker has in store for the coming months.

The company has so far proved relatively adept at selling its products in a tough economic environment, even as some of its peers have struggled. But Apple's shares have surged about 50 percent to above $120 since touching a 52-week low in January, leading some to wonder how much momentum is left in the stock given the uncertainty in the economy.

Analysts say a short-term sell-off is possible, assuming that earnings are in line with Wall Street expectations and Apple gives a typically conservative outlook. But they also say some investors will continue to buy the stock in anticipation of what the company has in the pipeline.
