As of April 26 Apple was on Cramer's sell list. Late yesterday he was hyping it. He's no analyst, seer, or technician. Cramer is for entertainment only. Don't use his opinion as a thermometer for investing. A grocery bagboy's opinion is about as useful.
Don't blame him. Nobody except the insiders knew Apple would come up with such mammoth dividend and repurchase program on April 26. The sentiment changed because of that. If Apple hadn't announced the cash plan, would you still be "strong buy"?
