"Grasping" would not be the word that I would use... sounds a little desperate to me...
However, I agree with your basic point that this company is still seeking to build credibility with the more seasoned investment community... in that light... the PR this week did not help them...
That credibility will only be built on the science, and on the transparency and reproducibility of positive findings... the PR left me with more questions than answers... what exactly changed between not stat sig and stat sig? Spell that out for me and you have my attention... I have taken an initial position with AMBS, but will need more to continue accumulation... clearly the larger market feels the same at this point...
