Big short interest in PVA -- a possible explanation
MHR has 9 million more PVA shares (from the EF acreage deal) they seem to want to sell.
Shorts may be figuring that will keep PVA upside very limited for awhile.
Or MHR may be shorting against the box -- shorting shares they won't have to cover.
I could be wrong but I think the shorting is mainly for technical reasons and not because PVA is a bad investment.
