Comparing S&P500 Index and its components to see relationship


New Member
Hi, I have weekly price data for S&P500 Index and 50 of its components, total number of observations is around 9000. Requirement for project is to see relationship beween index and its components, when S&P moves do components move in same direction or other direction. I have done correlation and regression and it seems like some indexes move in same direction and some in other.
What else can I do to see this relationship? This is for undergrad Statistics so not too technical and I can research and learn about any additional tests that you might suggest, all I need are the names of tests.
Thank you.
