Let's face it folks, S&P 500 is by far the greatest financial invention like ever. It was built on the bases of going up forever, since years any dip on this instrument was an automatic buy for me. it boy oh boy it always paid off really well.
Talking about fundamentals: First of all they don't matter , if they matter, they are already priced in. We the humans want to take this higher and no one can stop us.
This is not financial advice, Do your own DD.
