Good piece

Rather than suppose why not try, the data is all there, it takes a few lines of a bash script to download the data (stuff that actually exists rather than supposition), do the counting and produce a csv file you can put into whatever graphing tool you like and see what you get?

And if you can't be bothered to do that, don't start whining when your pension or 401k plan, doesn't "perform" like you were told...
