Because the TNX(interest rate on the 10Y treasury note) has pulled back a bit. This is a snapback mean reversion that will be met with another snapback reversion. Broad market relief cannot happen with 10Y interest rate at current levels. Needs to come down from mid 3s to mid 1s, or bond market will break. Investment bond market already broke and fed stepped in to save it. Wont be saved by fed again. Too many holes in the dam to fill at once.
