Yield ceiling is 2.64 rapidly approaching. Doesn't look like the US equities are particularly getting scared in more expensive money. Sept 2017 is the start of the bond sell off but since then the US equities continued to power into record breaking levels. I would be hesitant to call market selloff or collapse through a bond selloff.
If you look at late 2016 which I am guessing is the signal from Feds of their likelihood of a bond reduction on their books with the spike in yields BUT the US equities continued to power up unabated. So on what basis are you making your hypothesis?
