“Expectations for Apple’s third-quarter results were high, and the company handily crushed them,” investment researcher Morningstar said in a note.

“Apple is an exceptional company with a clear and convincing investment case and high return potential,” added analysts at Indigo Equity Research. “High sales growth and increasing margins have led to a remarkable explosion of earnings growth since 2003. This has been from a few products in high growth segments (iPods, iPhones & iPads), as well as laptops.”
