Look at the ASX short selling tables, it's being shorted to drive the price down and create panic and right now they are picking up a reasonable chunk at a discount, I don't think there is anything to panic about.
If you look at the volumes yesterday it was shorted about 300,000 units and today over 900,000 units have been picked up at a reasonable discount so I think they have archived there objective.
The type of company ybr is you can't be a short term investor in it and expect a quick return - the fundamentals have not changed, they aren't bleeding money and they are kicking goals so I think it's still a company to watch and accumulate - even if it takes them an extra 6 - 12 months.
