GBPJPY and ES mirror each other

Well, it kind of looks like it. Last Tuesday I was trading GBPJPY and the way the price action moved that day felt tight and compacted. When i was skipping through charts of the S&P this morning, I was surprised to see such a tight mirroring of price. I don't really like the concept of correlations, so i'm gonna avoid that word. I don't think they are correlated, but perhaps pound yen is a proxy for 'risk on/risk off' sentiment at the moment.

Not taking anything more from this than the observation.
