VCLT
DXY
I think there is some negative relation between $DXY and $VCLT.
Therefore watch out what the $DXY is doing Since it seems that when it goes up $VCLT goes down.
Dollar strength not good for long term corporate bonds it seems.
I imagine that it's because the market goes into short term treasury or longterm government bonds and avoids corporate bonds.
if anyone knows more let me know in the comments.
