By correlation, are you referring to the statistical measurement of the relationship between two variables? Wherein, if the correlation is...

-1 = indicates Negative Relation (i.e. stocks move in opposite direction)

0 = indicates No Relation

+1 = indicates Positive Relation (i.e. stocks move in same direction)

In any case, you'll have to clarify how to use this data...(atleast I've not understood it)

@zeekid
This chart indicates connected stocks move togather. i.e if one stock goes up other stock also goes up and also vice versa. Day trader can take advatage of lagged response of depending stock.

@pasha
Created using graphviz opensource graph generation tool.

I have updated and added company names to the graphs. Since these are too large to post here, I am posting ********** links.

@pasha
correlation over shorter time periods is not preferable since it could generate lot of false positives.

Now I am trying to findout stocks which are performing identical to the last year quarter. Once the study is completed I will post table of stocks.

I meant to ask what software is doing the correlation? Do you have any correlation graphs?

I wrote it myself to caliculate the correlations and then passing that data to graphviz to generate, I myself don't use any other software.
