Thanks stlamc - I think you are onto something, and am watching this with interest. A few weeks back there seemed to be a 'ceiling' at 75c which coincided with the start of the increase in short sales. Ceiling got broken a couple of times (27/4 and 1/5), and each time the next day it was slammed down to 72/72.5. Like you I favour accumulation as the reason rather than insiders with knowledge selling down (which would see a decrease in price with the increase in short sales, rather than a steady price as you say). See figures below- lower one is % shorted.
Interesting indeed.
