Yea the shorters are having a field day at the moment. just keep in mind that at some stage they will need to cover their positions. Volume today is pretty light (with the exception of one ~300k tranche).
Keep in mind that the directors were buying not insignificant amounts (about 1m volume between four of them) in mid oct 2015 at $1.52. Usually the best sign of insiders' views of the company when they put their money alongside investors!
