Portfolio variance is a measure of dispersion of returns of a portfolio. Now let's jump to the variance part: Conditional variance Process (Second moment) Similarly that for the mean process, we are able to estimate the unconditional variance of our return serie using a simple variance formula $\sigma^{2} = Var(r_{t})$. CI - confidence interval. The standard hours are the total number of hours required to complete the production target during a particular period. It is not stated that it is a portfolio of some option with x delta so I assume it is a portfolio of all linear instruments (also the statement about equities seems to hint at this too). 69% and the long-run volatility is 2%.
