Markets, however, rarely make a trade so easy, and after a couple days of tepid strength, the yen rolled over and broke to new lows. Is the BoJ losing control? I don't think so. A more likely scenario is that the early chasers of this announcement are being shaken out.
That massive volume under the breakdown is a tell-tale sign of stops being run. If we see the yen reverse the breakdown in coming hours, a huge snap-back rally could develop.
