Can someone explain to me why it is that CS stock dropped over 10% over the news that the SNB want the two major swiss banks to lower there exposure but UBS only had a min. drop ?

There could be thousands of different reasons, starting with the amount of exposure each bank has to certain markets - and how much they have in reserve.

Markets are very emotional creatures - and the market reaction does not necessarily reflect reality. It is better to look at the facts and put a picture together yourself, than rely on external opinion to shape your investment strategy. As Michael Lewis wrote in Liar's Poker, those who know don't tell - and those who tell don't know.

Ive been holding some UBS for a while now and cant wait to dump them but got the shock of my life yesterday when i saw CS drop 10% and as i scrolled down and saw UBS i was a little relived..

Its a crazy world we live in !!

As eluded to above, Credit Suisse has "further to go" in terms of improving its capital ratio. Both banks have the same target to acheive by 2019, UBS is ahead of CS on its progress towards this (by about 4bn). In addition, CS may have to cut dividend, which it has paid every year for 150 years. UBS may have to as well, but only started it again this year.

Poor form by the SNB in the way it was announced i'd say.
