Funny thing about Motley Fool and Apple.
In 2005, I took Motley Fool's advice and sold my Apple stock. Their argument then was that the company had nowhere to go because the Windows PC market was too entrenched, especially with businesses. Maybe they could sell a few more iPods or something, but no real big growth potential. I had gotten about 50% growth to show for my investment, so I cashed out while I was ahead. 30-some bucks a share.
I wish I could find the article, but it's ancient by internet standards, and probably buried by a couple of CMS migrations. My experience is only one data point, but oh wow were they wrong on that one.
why do I say that (only half in jest)? because i bet Tesla has more room for growth than Apple in the future. my bet on Apple is that in the short-term it's going to continue to get better but in the longer term it will decline, if only because of Jobs age and health issues. I admire the guy but I think he's closer to the end of his career than the beginning, and Apple stocks are currently very very expensive whereas Tesla is stilly relative cheap in comparison. If Jobs leaves, and especially if just a few more people near the top leave, and the top of the company becomes more mediocre/tasteless/corporate-crapitude like Microsoft then I think it will flow downhill from there and they'll lose their "premium"/talent edge over Microsoft.
Of course, none of us can predict the future, but that's how I'm betting.
