When Everything Else Fails, There is Hope of a “Puetz Window”

The rebound in stocks after the March 2009 bottom will be entering its twelfth year soon. Fundamentals and technicals have disappointed bears in forecasting major tops and some have turned to idiosyncratic methods including astrology. A new “Puetz window” presents an opportunity according to some.

I specifically wrote about a rebound because there is a misconception among many analysts that the bull market started in 2009. As I wrote in July 2016, the bull market started in 2013.

The bull market is actually in its eighth year although the rebound started nearly 12 years ago.

Nothing has worked for the bears, especially in the last seven years, technicals or fundamentals. There is hope now because of a “Puetz window.” What is that?

Steve Puetz has studied market cycles. Among his interesting work is the analysis of cycles triggered by lunar and solar eclipses. The “Puetz window” opens after the first full moon following a solar eclipse when there is also a lunar eclipse. Does this sound complicated? Here is a chart with the 1987 crash.

After a solar eclipse, there was a full moon and lunar eclipse.  Then the market crashed.

I suspect this astrological pattern was fitted on historical data. It was determined that in about eight major market crashes in the past, including the Tulip Mania, this astrological pattern was present.  But in some other crashes it was not present. But in all eight it was. Other times it was present but nothing happened.

Or as the Twitter meme goes: “60% of the time it works every time.”

For example it did not work in 2013 despite high expectations.

The bull market continued in all strength damaging those who placed their short bets based on a “Puetz window.”

One of the problems here is that as I argue in my book Fooled by Technical Analysis, patterns are neither necessity nor sufficiency.

These patterns are not necessary for a major crash and they are also not sufficient.

In addition, win rate is not enough. One must know the expectation from those patterns. In fact, a 50-day/200-day simple moving average cross may do better in signaling major bear markets and capturing some of the downside. Click here for a more advanced example of an adaptive moving average long-short system.

I have not done a quantitative analysis for the “Puetz window” so I cannot present any results. I would not spend any time doing it either. The first ever article in this blog was triggered by analysis from a major investment bank about trading moon phases. Please excuse the format because that was my first WordPress article and click on images to make them visible. In a nutshell, the results were flawed because staying out of the market between moon phases reduced exposure to bear market. One could have done that with a moving average cross-over.

Next, there is now a “Puetz window” as of Friday, January 10, 2020.

If a crash starts, should we attribute it to a astrological pattern?

I think the proponents of the method will argue that we should.

If a crash does not start as in 2013, the proponents will say that this time it did not work but all the times it worked, it worked.

In fact, 60% of the time they will say, it worked every time.
