I have been noticing that since last Fall. I was thinking that someone is dumping large blocks to trigger computerized auto sales then turning around and purchasing increasingly larger positions. I have just used it as a buying opportunity and have been periodically adding to my position since last May.
I am staying long. Zohydro is only part of this equation. Dose pro technology could be the main driving force several years down the road. It is much safer than needles for various reasons and the number of medications using it will mushroom in the coming years.
