That totally depends on how you define "problem". I believe the market will definitely have a problem with the current asking price of the owners for 1 share of the company if the iphone stops being a thing. This will make the owners very worried indeed.
A stock market crash is always coming. If you can't say if it's coming next month, next year or next decade, then the statement contains no information.
And you complain about a statement containing no information?
The thing is, no one knows exactly when a crash will happen.
But some people know that one will happen say, within the next five years, and that it's going to be worse than 2008 and 2001 because the underlying problems have only been getting worse.
Listen gais!!!! A market crash is comming! I read it on a blog. Brace yourselves! (You heard it here first)
Do you also think Greece's problem of having way too much debt was fixed by loaning it ~80B dollars more?
