Apple is a holding in Jim Cramer's Action Alerts PLUScharitable trust portfolio.

"While investors may be disappointed with the initial 2Q guidance, we'll absorb details of the company's call before we make any judgments," wrote Cramer and Jack Mohr, research director of Action Alerts PLUS." As for the iPhone, units sold came in almost exactly in line with what was expected given that Cook previously had mentioned that they would not be down year over year. Ultimately, we believe that expectations have been reset for the year and the company is set up to outperform given the many catalysts (China, new iPhone upgrade program, new phone models) throughout the balance of this year and in the future."
