Supposedly the rules are that you can not list a note with a negative YTM nor any note with a positive YTM but >70% markup - it must be 70% or less mark up and generate a positive YTM. However, it has long been that even when the YTM is positive, Folio will randomly tell me that a note I have at 69% or 68% "...can only be listed for sale with up to a 70% premium..." Occasionally it would tell me that a note at 67% is still >70% and I have just dealt with it and lowered the price. But in the last few weeks it has gotten worse and even notes at 59% premium (with a positive YTM) I get told that it's >70% and I need to reduce it! I had to list it at 58.72% - it wouldn't even accept 58.81%. This is occurring randomly as other notes list without issue at ~69%. More fuzzy math. . .
