Nikkei 225 leading the way again?

The Nikkei 225 has hit a block in the road today. On Friday the index rose above 38k and that is quite a rebound from the falls towards 31k on August 5. The Nikkei had closed on Friday at 38,062 and it topped out earlier today at 38,125. The index has now closed for the day, with a loss of 674 points and of course that relapse has taken the USD/JPY sharply lower with it. The Nikkei futures are in the red following that close. This fall is adding pressure onto the European and US futures and it seems that the Nikkei might be leading the way again, as indeed it did exactly two weeks ago. If that is the case, then we could see more downside to come for the rest of the global stock markets as the day further unfolds. The Nikkei 225 futures are just now pricing a reopening for tomorrow at below 37,200
