re: Dow normally dips during the summer?

The idea of seasonal trends is very similar to the idea of other market anomalies (i.e. January Effect).

There is a fundamental flaw with consistently repetitive patters and this is why market timing is a near impossibility:

If there is any real correlation to these so-called patterns then by the time the market has "realized" these effects, then it becomes a part of the efficiency and rational investors eventually dilute any correlation.

Although your chart does supports January returns pretty well. I would like to see a 10/20/30 year monthly returns.
