Iconoclast's awesome digging for the article on BTD got me to check my SA feed for news and it turns out Resverlogix is one of the stocks mentioned as having the highest borrowing fees.

The thrust of the article is that the listed stocks are "obvious shorts" and in broad strokes I don't disagree....shorts take on much greater risk than longs, and as such when they pile on a stock causing borrowing rates to spike, it should give investors pause.  

But in the case of Resverlogix the reason for the high borrowing cost is not that shorts have piled on, quite to the contrary short interest in Resverlogix as we all know is incredibly small....less than one half of one single percent of the ~210 million outstanding.  Actually its less than 2 tenths of a single percent.  

The reason for the high borrowing cost is obvious to me, its because there simply are precious few shares available to be borrowed, which speaks to what everyone here says about Resverlogix, that it is incredibly tightly held.  

The downside of the incredibly low level of short interest is that it pretty much eliminates the potential for a monster short squeeze, something that many pundits believe was the cause behind Tesla's monstser run recently.  

Happy weekend.
