Interesting AVXL Plots around Dec1
(This is not technical analysis...just data analysis!)
I decided to look at this data as that time period was very interesting.

Below are two plots.
The first is a composite plot, by day, of Total Volume of AVXL, Total Short Volume of AVXL, Closing Price, and Short interest as a percentage of total volume.

The second is a plot of the millions of dollars of AVXL stock that was shorted...In this case income to the shorter.

Several interesting points from the composite plot:
1) Note how the Short Volume and Total Volume track so closely (Blue and Green).
2) The percentage of Short to total volume (Purple) stays fairly well within a band of 20% to 35%.
3) For all the volume, the SP(Red) stays within a range of $13 to $7.7 from 11/17 thru 12/9. A fairly narrow range considering the massive volume swings.

Questions raised:
A) Is it a coincidence that the Short Volume tracks Total Volume so closely, and around 20% to 35%?
Related to this, is there an algorithm specifying this percentage in some buy/sell program(s)?
B) It appears the price stayed in a narrow range (in my opinion). Was the above mentioned algorithm used to maintain the price level, or is this just an interesting observation/coincidence?

Regarding the second plot of millions of dollars shorting AVXL...your questions and conclusions are as good as mine.
