I would leave the shares in your us account, i would not cash out and convert to euros, you could always sell the shares in your company and buy some other solid US blue chip, coca cola, american express, or even big railway stocks which buffet has been buying, the dollar has been falling for years however i still cannot see it falling much further against the euro, although i also thought this at $1.35, i think $1.50 and then stabilisation, the euro is not a rock solid bastion of stability the higher it goes the more likely countries will want to break free like spain, italy and ireland who are finding it impossible to live in it at these levels
