There is a lack of very positive news being worked into a "general positivity" meaning macro news such as employment, gdp growth, falling inflation, positive news spun in a positive way, etc etc means the USA continues to "lose despite winning." Great time to take a lot of money off the table given the spectacular run since the "Treasury Secretary low" of Christmas.
Atlanta Fed has posted a material slowdown in gdp as here and now.
Treasuries yields have fallen.
"growth" as "moar woar" is always problematic.
The existing war(s) are of course problematic.
Only estimates can be made of spending and tax collection going on decades now.
