## How is correlation related to the expected return on a portfolio?

Correlation is measured on a scale of -1.0 to +1.0: If two assets have an expected return correlation of 1.0, that means they are perfectly correlated. If one gains 5%, the other gains 5%. A perfectly negative correlation (-1.0) implies that one asset’s gain is proportionally matched by the other asset’s loss.

## How do you calculate portfolio correlation?

To calculate the portfolio variance of securities in a portfolio, multiply the squared weight of each security by the corresponding variance of the security and add two multiplied by the weighted average of the securities multiplied by the covariance between the securities.

What is portfolio correlation?

When it comes to diversified portfolios, correlation represents the degree of relationship between the price movements of different assets included in the portfolio. If two pairs of assets offer the same return at the same risk, choosing the pair that is less correlated decreases the overall risk of the portfolio.

What is expected return of portfolio?
