I understand the notion of the market being memory-less and we should not use the history to make future decision. Also, I see in this site there are mentions of specific times in a year where the stock markets "tends" to go up or down.
I am searching for a graph tool that will allow me to map the dow jones or s&p indexes in a year over year fashion.
For example, instead of http://finance.google.com/ where it shows the S&P in a linear fashion all the way 10years back, where I can see year 2011 in red line from January to Dec, and year 2010 in a green line, etc.
Any ideas?
