The SP500 hitting highs is a lot less good news when you realize most of that is simply due to the dollar devaluing against other international currencies.
That isn't asset appreciation, it's currency devaluation.
EDIT:
I m on mobile and don't have the ability to make my own chart with DXY and SP500 normalized to each other, but uh...

Look at this in YTD, then in 1Y, then 5Y.
Normally, these two things move in the same dirrction, though the SP500 tends to grow much more when the DXY grows a little.
Well, now, basicslly since Trump took office, they're moving in the opposite direction.
So, yeah, this is now what is called a 'melt up', where stocks climb higher, but not because of any kind of underlying fundamental strength of the US economy but because the USD has lost about 10% of its value compared to the currencies it most often is traded against.
