Based on the increased volume at higher prices towards the end of the week on a Friday, it is possible that RIMM can get to these price soon, if not on Monday soon after that. Looks like some big money was accumulating. We will see.
I think yours is a more realistic assessment of price move.
To me the surge in volume and price increase in the last hour on Frdiay was an indication of some shorts deciding the party was over for them and better to get out now than drop more of their gain, due to greed.
