FXCM's resident technical "expert" is talking massive gains still to come for the dollar (1.13 for Euro, 1.35 for Swissie, 1.64(??) for Cable) So on that basis, Yen is still in for a shafting.
IMHO, lots of good news coming out of Japan, but it's all being ignored, and another FXCM nugget is their Speculative Sentiment index which has Yen longs at 6x Dollar longs.... and you know that 90% lose in this game. So I guess we won't see any meaningful reversal until the crowd throw the towel in.
Having said all that, corporate activity seemed to suggest 1.15 as a top (again from FXCM's SS index)
Be lucky
