The graphic below shows PTR's
Visual Elliptical Fitting Analysis (VEFA) applied to a S&P
500 "cash" index's (SPX), monthly chart from 1999 to 12/2006 and the weekly
chart from 2002 to 3/2006, in order to locate any periodic (regular and
reliable), semi-periodic, or reoccurring only cycles...if they exist.
The curves are only a "what if" construction and they should not be
used without other methods to trade with.
NOTE THAT these two graphics are for the one-year "seasonal" cycle
and the 13 week "earnings" cycle only, as the longer term 2y, 4y, 8y, 20y,
and 40y cycle analysis is on another graphic...which is strictly limited
to subscribers only.
