I'm not familiar with how correlation is measured, but isn't it a statistical formula, rather than a chart?
I personally am using the term correlation loosely here. It's easy to do a correlation analysis using the Excel function CORREL. One just gets the monthly data from Yahoo and runs the function.
By why do a formal correlation? You can see from the charts and performance data that these are not highly correlated markets. Yes there is some mild correlation but nothing like > 0.90. In the crash of 2008 the correlation went up. Is another one coming? Who knows.
A question comes to mind. Is it possible that correlation is coming into play in the last year or so? Perhaps a weak correlation is growing stronger?
I think we've established that there is some correlation, but it is not >.90.Comparing the gradients of the two charts might be instructive.
As mentioned in my second post quoted above, based on recent reading in the last year, some believe that these two markets have become recently correlated, but the long-term relationship is uncorrelated. One graph for a shorter time period probably requires more data.
Of course anyone can look at one graph, and see a gradient. It is what it is, I suppose.
