精 老師,這是我在題目的答案中總結(jié)的關(guān)于蒙特卡洛模擬的以下5個優(yōu)點,麻煩老師講解下如何通俗的理解一下,不然總是記不??? (1)Monte Carlo simulations allow for portfolio rebalancing under changing tax rates and in multi-period situations. Finnegan’s effective tax rate will likely increase sharply when she starts a new job. MVO does not consider these factors. (2)Monte Carlo simulations can compute path-dependent terminal wealth;(路徑依賴是什么意思?) (3)Monte Carlo simulation is able to incorporate the effect of changes to variables over time. MVO is a single-period framework (4)Monte Carlo analysis allows Loucks to analyze different rebalancing policies and their costs over time (5)Monte Carlo can incorporate statistical properties outside the normal distribution, such as skewness and excess kurtosis, It can also be incorporated in alternative investments (such as private equity, real estate, and commodities),
