"One man's loss is another man's gain" is the first thing that i could think of when news of JPN central bank increase their QE again. By weakening own currency to boost company's earning (stock) or boost US dollar, or more strategy they have own in their sleeve, i learn a lesson from here.
QE not necessarily must come from Mdm Y, today JPN had one, perhaps CN or Europe will follow suit.
Having say that: Using the last high from 2007, we have the price approaching the monthly 76.4 retracement @112.657
I anticipate two scenarios (out of others):
Path 1. price will just break the resistance like nobody's business and go all up to test 124.130 OR Path 2. price will pull back to highlighted region (99.823 - 105.559) before continuing the uptrend
