| | | RtS, of course you should complain when I post data or a link that is wrong! No offense taken and I hope none given. I read the readers' comments for Hulbert's article and they were not useful. Usually I do not double-check data in an article before I link to it.
Your volume data shows none of the 4 exchanges had an up/down volume ratio near 9:1 on Friday. Do you usually look at all exchanges or only NYSE?
Taking this ratio more seriously than I used to, I found this stockcharts.com
if you go to the above link, scroll down about 2/3 of the page to find this:
Zweig Up Volume Indicator
Show Zweig Double 9 Down Volume Ratio and Zweig Double 9 Up volume ratio.
Author/Creator: Martin Zweig
Data components required: Up Volume (UV), Down Volume (DV).
Description: This is another of Dr. Martin Zweig’s momentum indicators. This one uses a ratio of up volume and down volume. This ratio shows the powerful thrust of the market and cannot be ignored.
Interpretation: Whenever the ratio reaches 9 to 1, a good buying opportunity exists. There have been 53 signals given since 1965. The biggest ratio ever was on August 17, 1982, the beginning of an 18 year bull market. The chart below shows each occurrence of the 9 to 1 up volume ratio since 1965, identified by the down spikes that go down to -9. You will notice in chart 8-24 that they generally happen near significant, certainly tradable, market bottoms.
Chart 8-24
A further concept from Dr. Zweig is to expand the 9 to 1 ratio of up volume to down volume to state that anytime there are two signals in any 3 month period, the evidence suggests a strong market to follow. Since 1965 there have been 21 of these “double nine” signals.
Here is a video interview I did last month. Click Here.
Trade well,
