Ahh, ok. When you want to say that Sony shares doubled in price in Japanese Yen, in the future, specify that, instead of simply saying that they doubled in price.
What you are saying is reducible to the statement "The Japanese yen is considerably weaker against the US dollar than at the start of the year. You are not saying that Sony is doing well, just that the Yen is doing poorly.
