She states thshe hasa significant portion of her portfolio in short-term bon anmoney marketfun to offset the risk of her AutoPshares. Owen points out to Steven thather current portfolio is subjeto mentaccounting, is not constructeinlayers, anes not take into consiration covarianbetween assets.Is Owen’s comment regarngSteven’s current portfolio correct? A.No, he is incorrewithregarto portfolio construction B.Yes C.No, he incorrewith regaro covarianbetween assets A is correct.Owen’s comment regarng Steven’s current portfolio construction is not correct. Her current portfolio is subjeto mentaccounting, hbeen constructein layers anes not take into consiration covarianbetween assets. 老师请问，C是不对的，那就是说covarianbetween asset观点是正确的，题目covarianbetween asset的观点是没有考虑资产间的协方差，对吧？为何加入了short term bon资产表示没有考虑资产间的协方差呢？
