Not much apparently. The Nikkei 225 stock index really started to out-perform.

But how much is too much? I suppose you never know until the market speaks.

Well, the market (which is us) is getting nervous. Trading in Japan is becoming a daytrading thing, with incredible moves up and then down, and back up again.

Today, the Nikkei Dow was down " a lot. In fact, it was down almost -1.5 pct in the morning session alone. In U.S. Dow points that's over 150.

Who knows where the Nikkei 225 is going tomorrow? I certainly don't.

But smart traders will watch their basket of stocks much more closely at times like this. And when market moves get too extreme, many traders will scale back their positions, including reducing their leverage.

They know that portfolio risk management is more important than searching for reward, particularly at times like this.
