5 000 is just a number.
Were USA really in any better shape two years ago when the index was at an all time high?
NOT BY MUCH.
Because there was a deficit budget, a costly war and people were spending money that weren't their own.
This is all about adjusting to reality.
Stop looking at the index. Look at the p/e numbers, look for how the order books look et al.
That's a real indicator.
