The Sordid Past of Years Ending in “7”

  • SumoMe

Don’t worry, this story does not involve Russian hookers (nor Blue Dresses).  It is still a pretty sordid tale.

In Months to Beware of in 2017 I included certain months “within Years Ending in 7” as months to be cautious.  The “Years Ending in 7” seems pretty obscure but is founded in the “typical” pattern for the stock market across a given decade.  Figure 1 below is from something written by Martin Pring in 2009 or 2010.  But it shows a chart with the “typical Decennial Pattern” (he draws three lines, one for secular bull markets, one for secular bear markets and one for “All Decades” the blue line in the middle).  Note that Years 7 within a secular bull market tend to take a big hit in the 2nd half of the year.decennial patternFigure 1 – The Decennial Stock Market Pattern (Martin Pring)

Note the tendency for a meaningful decline during Year 7.  If you click on the link above and scroll down to Page 11 you can see the decade-by-decade results for the Dow. Here is what you’ll find:

Years that witnessed a meaningful decline:

1907

1917

1937

1957

1977

1987

2007

Year that witnessed intermediate-term tops

1947

1967

1997

Years relatively unaffected

1927

Note that 1927 is the only Year 7 that escaped relatively unscathed.  So that’s why “Years Ending in 7” was included in Months to Beware of in 2017.  Does any of this guarantee a bad year for the stock market in 2017?  Not at all.  But – referencing my earlier article – the months of February and especially September and October has witnessed alot of stock market  mayhem  during Years ending in “7”.

Here’s hoping that 2017 will  be the exception to the rule.
