In the world of Vanguard, I'm talking VGSH, VGIT, VGLT, VGT, but open to others. In all the record-high yields from the mess with the US debt this week, I'm surprised that none of the above's NAV have really moved that much in response, as I would think people would want to buy in now to reap the greater yield payouts for longer.
What am I not understanding about treasury ETFs in this situation?
