The crash of the Dow Jones Industrials in 1929 was signaled by the development of a well defined head and shoulder pattern, seen most clearly in its monthly chart. It is a reliable pattern that captures the behavior of investors who are becoming increasingly disillusioned about the future prospects for economic growth.
The downside pattern targets in the 1929 Dow were exceeded with a fall of around 49% before the market recovered in 1930. The 2008 dow pattern targets were also exceeded with a market fall of around 52%.
In 1930, the market developed an inverted head and shoulder rebound pattern recovery that led to a 46% rise in the market. The Dow rebound in 2009 also developed from an inverted head and shoulder pattern. This was a powerful rise of around 69%.
The historical development of the recovery in the DOW in 1930 ended with a new head and shoulder pattern. This was followed by a rapid market decline that created the first part of a long term double dip pattern. This retreat also exceeded the pattern projection targets with a fall of 28%.
Fast forward to today, we're seeing the Dow is developing a new head and shoulder pattern which indicates a beginning of a bear market. The rally peaks in the Dow appear in January and May and June. The downside projection taken from the neckline of the pattern sets a target at 8,400, or a 25% decline.
A very bearish analysis using the pattern of retreat behavior in 1930 suggests the Dow could retreat to around 7,500 in 2010.
The head and shoulder pattern in the Dow and its downside targets, are invalidated with a sustainable rise above 10,600. A move above this level does not signal a resumption of the uptrend, but it does reduce the probability of a double dip.
It must be noted that while the behavioral patterns in 1930 and 2010 are similar, they don't necessary point to the same result. But it does sound a warning that markets could continue to stand on the edge of a precipice.
