Subject: Re: Value, when to buy
One more question, if I may. Have you tried other time intervals besides 20 years, say 30 years.

There is no particular time interval involved in creating the whole line. As mentioned, this is not a trend line fit, a technique which has no theoretical meaning or predictive power. This is just a moving average of very recent financial figures, average age under 1.5 years.

The 20 years of data was used only to set the scale...to move the entire resulting line up or down so the moving average line overlaps the price line better.
