Sell S19s

There have only been 7 Sell S19s since 1928.  Only one called a significant top.
This was the one in 1971.  The S19s occur when the P-Indicator turns negative
after being positive for 105+ straight days.  The DJI must not be more than 1/2%
below the 21-day ma. The furthest up off the 21-day ma it has been on a Sell S19
is 1.59% above it. That case also saw the biggest gain. So, the limit to how high
the DJI may be over the 21-dma should probably remain open. 

A high IP21 up to +.076 does not pose a problem for S17s nor does
an only slightly negative V-Indicator. Both of these brought the biggest gains.


Other key values ranges can be summarized as shown below.  In general,
the higher the other key values are when the Sell S19 occurs, the bigger
the decline.
                          

                                           High                                  Low
   AnnRoc                            .313 (+9.3% gain)           -.005 (+3.6% gain)
   IP21                                 .076 (+9.3% gain)           -.017 (+1.5% gain)
   V-I                                   -1 (+9.3% gain)               -149 (+3.6% gain)
   ObvPct                             .286 (+9.3% gain)          -.135  (+3.6% gain)
   65-day Pct Change          .193   (+3.9% gain)         +.055  (-0.2% loss)    
  
One could eliminate the single loss by requiring the 65-day Pct Change to
be above +.06.  Setting it above + .063 would only mean losing the
margin gain of .015 in 2007.     More evidence is needed to make this
change.
