I think the market is currently shaking within a frame of too many partly contradicting facts at the same time. The euro profits from the different policy of ecb and fed, but europe, and especially germany can not afford a still rising euro very much longer. I doubt the business cycle theory, europe was never ahead, why should it be now. Europe, and here again germany, still suffers from reStructuring cost.
I think Bush desperately needs this war in Iraq. He placed an expensive trade, already bears transaction cost, and now wants some profit. But its getting tough and tougher since Saddam does not give in, yet does not provoke too much mediainteresting anger.
To me Japan is somehow funny. The most busted economy does not react too much currently. It might be that 8000 for the Nikkei is the level the government is willing to defend by any means. Since they are already in debt by 150% of GDP, they do not care any longer on the one hand, but will be forced sooner or later to let the market go where it wants to go ...
I think the US still has the best position for recovery. There is no structural cost or crisis comparable to europe, which will face even increased restructuring cost with the new members in 2004. And Japan will sooner or later have to let some banks go bust and swallow all the trouble.
I think the straight line the Euro is currently showing against the dollar is a further indication for the comparably improving position of the US. Everybody wants a weak currency now - the US get it.
I would not bet too much on a Euro going to 120. If I was already in I would run the trend with a trailing stop. But I would not at all bet against that trend before it shows significant weakness.
