Sadly, shifts in the discussion of NWBO in social media has not presaged any great or sustained changes though with little else to talk about there is no blame in trying to tease out anything that might give a hint of the future.
To prove my point, look at how many discussions of "shorts are scared" have been had over the past decade and more and yet seldom, if ever did this talk presage a major positive change in the share price, to the point where if anything, readings of the tone could be a contraindicator of something positive happening.
I wish it were different but it's not.
