Probably tested the steeper trend line from below.

This would be a hint that some key players change their behavior for a while.
Pascal identified the NIRP-refugees as a likely dominant group.
I would add pension funds within the US doing something similar to NIRP-refugees: hunting for yield in US equities - or stop doing so for a while.
