I think we should all remember how low RVX was trading at the end of 2014...in and around 50 cents a share. That's a 500% gain from December's prices.
If more is coming, and I think it is....then I think once (if?) the PPS clears the 20 dma it could herald another big leap. Hopefully those behind the 200 odd thousands shares sold short have been able to cover.
