I feel like I might be overthinking this. I remember that the answer should be less than the highest individual standard deviation, but I’m torn between 6.9 and 7.7.
Wait, what? This question is throwing me off. I don't remember learning how to calculate portfolio standard deviation. I better review my notes before attempting this.
Okay, I think I know how to do this. I just need to apply the portfolio variance formula using the given weights and variances. Shouldn't be too tricky.
Hmm, I'm not sure how to approach this. The question doesn't provide much information about the individual securities. I'll have to think this through carefully.
This looks like a standard portfolio risk calculation question. I'll need to use the given weights and variances to compute the portfolio standard deviation.
