you know Martinghoul, you are a slick bastard, that I give you: Each time someone asks you to back up your outlandish claims you start asking back questions and accuse others that they do not get back to you.
Let's stick to the facts: You claimed there were big players who shorted at usdjpy 80 levels. I asked you several times who those players are you claimed exit. You evaded to answer and instead shoot back with other questions to never actually stick to a point and arrive at a common understanding. I told you several times that you can fuck off with this attitude, it does not fly with me. You make a claim and if others hold you to it then in most societies and social settings you better back up your claims in response else you will be painted as someone who bends the truth just to make his points. That is how you come across right now. I am waiting for your answer!
And shorting at 80 levels would have been a horrible trade, you clearly never traded currencies seriously, probably not even macro themes. Standing to gain 5% in the face of possible intervention or extreme short covering is not a trade any prudent hedge fund manager would undertake. Especially not in size. You can bullshit your way around this as much as you like.
In the spirit to answer questions, asked, here my reply: You said "Wait a sec, are you trying to tell me that exchange rates, sovereign bond yields, equity market levels etc accurately predict a country's future GDP growth/consumer wealth/house prices etc? In the longer term and proper context, whatever that actually means..." -> This I never said, nor meant, nor implied. Correlation does not imply predictive power whatsoever.
