The iPhone maker's stock has lost roughly 14 percent in the last 12 months as Wall Street soured on its prospects amid reports of iPhone production hiccups. CNBC reported Monday that, among analysts, Apple's stock is the most "unloved" it has been since 2005.
"In terms of the naysayer, I've heard this over and over again," Cook said in an exclusive interview with Jim Cramer. "I've heard it in 2001, I've heard it in 2005, in '7, in '8, in '10, in '12 and '13. You can probably find the same quotes from the same people over and over again."
"I'm not defensive on it. This is America and you can say what you want," Cook continued. "But ... my honest opinion is that there is a culture of innovation in Apple and that culture of innovation combined with these incredible, loyal customers, happy customers, this ecosystem, this virtuous ecosystem, is something that is probably underappreciated."
