Yen Devaluation:
For the last two and half months, 2012-11-15 to 2013-01-31, the performance of EWJ (iShare Japan) , YCS (Ultrashort Yen) and SNE (Sony) are as follows:
EWJ (8.8 to 9.97) 13% Gain
YCS (43.50 to 57.44) 32 % Gain
SNE (10.00 to 15.00) 50 % Gain.
Certainly, SNE performance was good and ahead of YCS since Las Vegas CES Show (Jan 7-10,2013).
Hope, Sony will do well in SmartPhone (New Sony Xperia Z ) and its Xperia Tablet Z in this year.
(Eating Apple Marketshare, if could......).
Good Luck for both long and short.
Sentiment: Strong Buy
