imo there are 2 factors supporting a move upwards - the drying up of sales that occur around a CR, and the gradual amortisation of the risk premium of holding TIS - relating to the ever shortening period of time between the present and the awarding of CE mark. Rises will of course be punctuated by bouts of profit taking but taking 2014 as a whole it is more likely than not to be a "good news year".
