Does anyone know of a place where I can find lists of correlated stocks? (leaving aside impactopia.com; I already used my free trial 3 weeks ago) Thanks Royce
try this-http://www.bullsector.com/ but, read my posts about correlation, if you want trade pairs, or try to build chart like i did.
Thanks for the link Bob. I especially like the combo quote page where you can see the thumbnail charts of the individual sector components. Thanks again, Royce
Can anyone tell me the formula to calculate the correlation coefficient? How are you calculating the correlations mathematically? What is the formuls used by Impactopia to calculate the correlation coefficient? How can I calculate the correlations between various stocks?
If you don't know the formula for correlation, you should be investing in a statistics book immediately. Otherwise, a simple web search will bring up a couple thousand examples of correlation coefficients and how to calculate the same. A good, basic site for statistics information is as follows: http://davidmlane.com/hyperstat/index.html and specifically on correlation: http://vassun.vassar.edu/~lowry/webtext.html Impactopia uses returns in their calculations; (someone correct me if I'm wrong on that) they also use one year of back data to do the calculation. And to calculate the correlations you will need data for each stock data series (you can download data for free from yahoo finance) for the lookback period over which you wish to capture the correlation coefficient.

You can download data in to excel and calculate correlation in it. The help file in excel explains how to do it pretty well. Corey

Hi, everyone. I just got back from vacation. Did not post for a while. Opened a new position today: DRI/APPB @ R= 0.7589. High correlation, same industry, better news for DRI today. Any thoughts? Al
