First off I want to say sorry if I am posting in the wrong section. Please move if so!

I understand many financial products and derivatives correlate with one another. Where is the best place to learn and understand this concept and stay up to date?

Thanks in advance!

There is a humongous amount of data you can ingest related to correlations. One of the simplest is interest rates go up and bond prices go down. In turn, as interest go up, banks gain more interest on new loans they offer which should boost financial stocks. The opposite should also hold true.

I could rattle off over a hundred similar situations. A good place to start (if you have time) sign up for CAIA Level I and CFA Level I exams to obtain the books and read them. It is probably the most comprehensive resource I have found to help with understanding basic concepts.

I hope this what you were asking and the information I provided has helped.
