Delta Factor: Second Draft

Below is the second draft of additional Delta Factor calculations.  As one can see from this table, the trends or signals arrive early.  I'm still not satisfied with the algorithm used to generate the Buy, Hold, and Sell signals for these ETFs.

The question of when to buy or sell an ETF comes up frequently.  I've been working on this problem for a year or more and still do not have a definitive answer.  Perhaps there is no right answer, only one of probabilities.  Below is a data table of my first draft effort to quantize whether or not it is time to Buy, Hold, or Sell the primary ETFs.  I am using iShare ETFs for this research as they have a longer record than the Vanguard ETFs. In this first effort I want to see how my algorithm works around critical market points.  I will fill in more dates later.
