Hi Guido,
This is pure speculation, but provided the general market remains fairly stable, I wouldn't be surprised to see TIS above $1 after sales begin. However that's assuming the current stock of VG gets the OK from the EMA. If not, and we have to produce a new batch, I'd be looking at 60 to 70 cents.
As I said though .... pure speculation ... don't bet the house on it!
Cheers
