Jim Cramer says Apple is still the 'greatest stock of all time'

Cramer said that investors should ignore negative calls about Apple and hold onto their stock.

He said that he considered Apple to be the greatest stock of all time and that he needed to know that he was still able to buy it.

Morgan Stanley estimated that the App store net revenue fell a record 5% last month due to a drop in gaming revenue as well as inflationary and recessionary factors.

In July, Apple said it expected less than 12% growth in services in the September quarter due to the strong dollar.

Cramer said that the company's products are too valuable for customers to stop using them. He said that investors shouldn't sell their Apple shares because of short-term concerns.

He said that Apple has been a great stock to own and a bad stock to trade.

Cramer's Charitable Trust is a shareholder in Apple.
