I think every time the market rises for a bit people are out with their vague claims of a correction... it gets a bit meaningless - the market might go down at some unspecified point in the future, might not be a crash or anything and it might well go up quite a lot more still before this apparent correction happens etc...
Unless you're able to accurately forecast or predict these things (
spoiler alert hardly anyone can, including plenty of hedge fund types - if you could you'd have such a huge edge and would be seriously wealthy) then it becomes meaningless.
I'd be wary of letting personal political views cloud judgement here too, orange man bad, Brexit etc.. doesn't necessarily translate into market going down - for example:
We all know Trump is an idiot, it doesn't necessarily mean you should take such drastic action or get too carried away w.r.t him being elected or Brexit happening etc... etc..
For the ordinary investor it's probably better to avoid attempting market timing - someone posted a fairly straightforward video giving a no nonsense explanation of this a while back (I think
@Raymond Lin IIRC). Non specific/vague claims that we're due a correction and then staying out as a result are probably a waste of time at best, if not actually damaging to your wealth with regards to your long term investments, historically buy and hold has done well regardless.
