Of them making us do the std. dev. of a portfolio on an exam is very high. They asked it on BOTH mock exams! (Saved the best for last question on #2, grrr). So right now we are batting 1000 for it. I hate that thing.
std. dev of a portfolio??? i hope they supply us with covariance and respective variances of the individual assets then!!
the last question in sample exam #2 is dealing with portfolio std. deviation it is largely conceputal and is part of a 2x4 for CML/SML
Yeah, they give you the covariance and expected returns std. deviations but it is the longest equation EVER. I get it, I just keep putting off memorizing it.
