Yeah I don't expect failure. they would not have made these visits to these conferences in my opinion to show failure. I could be wrong but they could have put out a simple pr instead of doing two conferences.
Binary events are all risk. Two of the stocks I was in had very good initial data but both did not meet primary end point for phrase 2. Also both company were very optimistic about results... From what I've seen in playing binary events, price drop or price increase does not really represent the result as I've seen both outcomes. I would say invest only what you can lose.
