what do you think about this:
- bitfinex fiat withdrawals are disabled
- people fear Gox specially with everyone repeating it online
- so they cancel fiat withdrawal and buy up bitcoin on bitfinex (price goes up)
- they withdraw bitcoin to other places (mostly bitstamp) and dump there (price goes down there)
- they withdraw their fiat out of fear.

this is more buy pressure on bitfinex and more sell pressure on stamp.
