Finding stocks that follow index

[Fibbo]

I want to find the stocks that follow index and those that doesn't. How ?
One way is to make spreads for each stock and look at those charts. That will that a long time, and how do I compare them to see which is closer to index ?
Isn't there any indicator that shows how close a stock follows index ?

You will want to calculate the correlation between the stock and the index.

That's very complicated. Isn't there any tool or indicator in any ta-program ? Any tool or scan that can be used to sort stocks relative to any index.
There is this Relative Strength, but I can't find it in my program.
