Dow about to take a dive
The entire formation from Mar 2009 to Aug 2013 has the right look of a idealized Elliott Wave major double zigzag correction.
Here is the textbook version of what this type of correction should look like. After a major correction such as this is completed we should expect the downwards trend to continue.
Now look at the 5 year chart of the Dow Industrials.
On closer inspection at the 2 yr chart we can see that the Nov 2011 to Aug 2013 correction is best counted as a single zigzag.
