Hello Peter,
Thank you for both your compliment and your suggestion for further research. I am pleased that you liked the post. Often, as a buy side portfolio manager I was shown charts by sell-side analysts or their firms' salespeople and asked to make important decisions based on the appearance of charts. I still see many investment blogs use charts - daily, in fact - where I am supposed to see some obvious relationship present in the movement of two lines. Hence, this post.
I had hoped that it would help folks to realize the limitations of solely looking at charts, when, in fact, the story of any time series is always more complicated.
With smiles,
Jason
