Any shortcuts on BAII Plus for Covariance or Variance of two asset portfolios?

[Benmar]

So, is there a BAII Plus shorcut or not for calculating portofio variance for 2 assets or not?

I am trying to use the calculator to calculate portfolio standard deviation of return (Example 12, page 488, CFA Level 1 official books - Ethics and Quant)

Is there a way?

Thanks.

These formulus look quite cumbersome. Don’t know if even worth it to do it on the exam or just guess. Might waste too much time unless their is a shortcut on BA II Plus

You should know the formula for the variance/standard deviation of a portfolio like the back of your hand.

Agreed. It’s actually not that hard to remember once you’ve used it a couple of times. It just looks intimidating as it’s such a lengthy formula. Remembering this formula has helped me feel a great deal smarter when talking to clients about diversification as well haha.
