IMO only, I believe the share price 'tanking' is a consequence of poor NASH results. Again, IMO it all seems to point to pre-market announcement sell off. Lets face it, people are in the 'know' and the history of IMC announcements clearly shows us that we get a positive announcement quickly followed by a negative one.
Conversely and more recently, we saw 'on-market buys' by directors just prior to a dramatic share price plunge. Why? Looks like a strategy to instil confidence into the market. Perhaps those NASH results are imminent?
Having said that, this company has a blockbuster IP and they will be worth mega-bucks in the future, there's little doubt about that, albeit that SH will have to sit this out for a bit longer than anticipated. I'm happy to wait.
