I dont think sterling is overly cheap even though its moved alot in the last few months, but a year or so ago 1 euro got you £0.85. It was almost parity with euro back in financial crisis which really hit irish economy. I think the time to be selling euros and buying sterling or dollars was 2012 and before when dollar was on the floor. Maybe when euro only getting £0.7 was the time to be selling sterling and when at £0.9 buying sterling and selling euros. Actually i dont think euros should be sold except for east european currencies like polish zloty. Im just giving thoughts here obviously brexit vote is going to have a big short term effect. But is sterling overly cheap in my opinion its not cheap at all
