Apple just experienced it's first revenue decline in 13 years, so what does that mean? Is the Apple era over?
All companies go though ups and downs, and Apple has had a great track record, so no - it's hardly going belly-up. It's true that sales are down across the product lines, but that just means that instead of selling gazillions of stuff, they are just selling less at the moment (still gazillions, though).
Apple needs something new to sell, I think - and not just another iPhone, or a variation of the Apple Watch. They are probably working on it now, and it just has not reached the rumor mill yet.
There may be an Apple car on the way, but that's probably a few years out and they are hardly going to sell huge numbers of cars right off the bat (I wouldn't think). Even so, I would not sell any Apple stocks quite yet (that is not investment advice, btw).
Apple has plenty of runway to change its revenue momentum, with a record $233 billion in assets waiting in its war chest. It is hiring teams to research new products involving virtual reality and automobiles, two sectors with a ton of growth potential. But so far, at least publicly, it has fallen behind competitors like Google and Facebook in those areas.
