JimFred, if you read the headline again, you'll see that I suggest the the Nikkei will play "catch-up" to the S&P, which means I'm looking for it to rally... not decline. I show that they are spread apart and that it would make sense that the Nikkei OUTPERFORMS the SPY from here.
It's interesting that one time the Nikkei jumped to catch up to the SPY and the other time the Nikkei fell by about 4% more. Who knows - it is a divergence. I'll add the ratio graph next to look at that.
