word choice - "You and your" vs. "Your and your"

Which is correct, and why?

identifying you and your competitors’ relative market performance

or

identifying your and your competitors’ relative market performance

Each entity is in possession of “relative market performance”, so I think grammar dictates both be your, but it sounds godawful.

Answer

It has to be your and your. If you don’t like it, you can say something like ‘...identifying your competitors' relative market performance as well as your own.’
