When it comes to a Company like SVFC you need to be aware of every little thing that is going on around them. Today's enormous run has come with very few actually knowing of the reason behind it. The best way that I have found to identify opportunities like this is through this free mobile newsletter. All you have to do is text "RUN" to 25827 so you can make sure you don't miss out on the next big run.
The run up in volume in my opinion has to do with the enlisting with global. I believe they have a working group of MMs that work in concert to apply pressure to the pps while at the same time the dilution is occuring. This covers up the amount of dilution. Otherwise you would see a rapid rise in pps during those 200 million days.
