同學(xué)您好
個(gè)人IPS的總結(jié)如下:
Monte Carlo simulation:蒙特卡洛模擬
? Advantages of Monte Carlo Simulation:蒙特卡洛模擬的優(yōu)點(diǎn)
? Its applicability to the client’s actual asset allocation. 適用于客戶的實(shí)際資產(chǎn)配置
? Aggregating the results of many trials of probability-based estimates of key variables, the overall probability of meeting retirement needs is generated, and it can flexibly model different scenarios and explore issues that are important to clients. 通過聚合許多基于概率的關(guān)鍵變量估計(jì)試驗(yàn)的結(jié)果,可以得出滿足退休需求的總體概率,并且可以靈活地對(duì)不同的方案進(jìn)行建模,并探索對(duì)客戶重要的問題 ★
? Limitations of Monte Carlo Simulation:蒙特卡洛模擬的局限性
? It is only a method of estimation; it cannot predict the future. 這只是一種估計(jì)的方法;它無法預(yù)測未來 ★
? The output from Monte Carlo simulation can be highly sensitive to small changes in input assumptions. 蒙特卡洛模擬的輸出對(duì)輸入假設(shè)的微小變化非常敏感(輸入變化一點(diǎn),輸出變化很大)★
? Monte Carlo output includes the probability of reaching a goal (or goals) but not necessarily the “shortfall magnitude.” 蒙特卡洛輸出包括達(dá)到一個(gè)目標(biāo)(或多個(gè)目標(biāo))的概率,但不一定是“缺口大小”

資產(chǎn)配置中的總結(jié)如下:
蒙特卡洛模擬,解決MVO只考慮單階段框架(single-period framework)的問題,方法:使用蒙特卡洛模擬
MCS優(yōu)點(diǎn)
? 蒙特卡洛模擬是多階段的(multi-period),動(dòng)態(tài)的(dynamic),由于現(xiàn)金流與收益的相互作用,財(cái)富的終值是路徑依賴的(Terminal wealth is path dependent because of the interaction of cash flows and returns),例如投資者在投資期間額外注資或者取出部分資金,就會(huì)影響最終收益率
? Paint a realistic picture of potential future outcomes. 預(yù)測未來潛在的結(jié)果的真實(shí)場景
? 考慮路徑依賴(path dependent),以及再平衡和稅(rebalancing and taxes)的建模(model)
