Everyone and their dog has been pivoting to ultra-short duration pseudo-cash bond ETFs in the fixed income balance of their portfolio and this is causing a sell-off of lots of corporate bond ETFs. LQD saw its fifth day of outflows which set a pandemic era record. This brought together a total of $856 million in investor outflows. This is part of a blogger trend where sentiment around investment-grade bonds is weakening. However, it's not because they are less likely to pay back but more a reflection of investment-grade corporate debt generally having a longer duration, which is the risk investors don’t want with upcoming rate hikes.
Finsum: The risk premium hasn’t changed with corporate debt just the term structure risk. Fundamentally these bonds could still be in a good place.
