JBL is the current US WWE champion who believes Apple CEO Steve Jobs has "revolutionised consumer electronics".
Even since Wednesday's revelation of Boot Camp, Apple's stock remains down 20 per cent from its 52-week high, JBL notes. "I believe this is a buying opportunity," he writes.
"Apple is a dream company. No debt, and over $10 per share in cash. Add to that the fact it is still a growth story and you have a stock that is cheap," he writes.
"I believe the growth days of Apple are still ahead," he concludes.
