Hypothetical Q

SAy you are given two expected returns for two different assets (Asset 1 and Asset 2). Assume they are equally weighted in a portfolio. Then you receive the actual return of the portfolio as X%. How do you calculate the correlation?

Is there any more information, and the correlation of what (the portfolio expected and actual returns, or the assets’ actual returns)?

Asset’s actual returns. Not an actual question just a thought so no numbers. but say asset 1’s expected return is 2%… asset 2’s expected return is 3%… equal weighted portfolio of the two assets. Actual return ends up being 1%… what is the correlation of the two assets?

Given only their expected returns and the portfolio’s return, you haven’t enough information to calculate the correlation of their returns.

That’s probably why I couldn’t arrive at an answer haha, thanks!
