This discussion turned into a discussion of fixed
period
"waves" based on a non-analytic method.
I prefer an analytic method for examining periods of
waves and use the Maximum Entropy method to measure
However, I take a simple approach for fixed wave
projections
and use a trading model based on fixed Cosine waves
and
trade at inflection points which are optimized for
lead/lag of
the fixed wave over a very long period of time.
The attached pictures indicate that MESA analysis says
that
there are 82 month, 108 month, and 262 month LONG
period waves in the DJIA from 1921 to now.
The results of each model and the composite model are
shown in the attached pictures.
