The long HaltGiven that it has been over 3 hours since the halt was announced I'm thinking we are awaiting good news because if the news were bad it would be a very straight forward news release.
Good news could be more complicated however as the release of good news could prompt wild speculation as to what RVX might be worth, something which the TSX tries to discourage . What might control speculation would be if there was a simultaneous release of a deal for RVX. DM has said previously that more than one pharma had completed their due diligence and were just awaiting results just as we are. Assuming the halt is due to the pending release of results, RVX has now taken care of the it's regulatory obligations wrt the fact there is material news and it could be that DM is now discussing deals with interested pharma. In my opinion the longer the halt the better news to a degree. If the news is good it would stand to reason that the better the news the greater the number of interested pharma and the longer the deal process would be.
If the news is very good I wouldn't be suprised if the halt lasted the rest of the day or perhaps longer.
All just my opinion
