If you look at a 5 year chart we are close to bottom. I bought shares today and it seemed dried up (not many people selling). Often times this will move on no news as it has in the past. I believe also with CES & the court case coming up in January we may hear "something" between now and then.
It’s likely associated with pending news. Most of us expect something much more than last year’s demo film. I personally expect to see a prototype or actual commercial product demonstration.
