I just don't see bitstamp rising much higher at the moment, not even to 120.
The problem bitstamp has is that while it is rising (as you described), mt.gox is falling (ever since that 1000BTC ask wall appeared, there has been downward pressure). And while bitstamp has been getting stronger - they are sustaining about the same volume as mt.gox at the moment
- they still can't defy mt.gox price leadership endlessly. Not when there is a huge mountain of BTC to buy up at the same time...

We are falling? Didn't really watch, but we are between 122-123 more than 4 hours.
