The issue with the story is that PBN will not do well if oil goes down....high cost & debt create leverage to oil....down is bad....up is good.....
A ton of energy plays are taking a pounding, even the ones with good balance sheets....likely folks who are switching up to plays that can last through a potential downturn so PBN gets hit harder....the potential recession questions and oil price questions are followed on by the uncertaintly with what to do with the dividend stream.
There doesn't always need to be a hidden story...I think you've hung around the Chinese stocks a bit too long....
