10、别是以马科维茨(HarryMarkowitz)的均值-方差模型为代表的现代投资组合理论。该理论主张，投资者在构建投资组合时，不应只关注单一资产的风险和收益，而应通过多元化投资，分散非系统性风险，从而实现投资组合的最优风险与收益平衡。Exponentialinvestment,asapassiveinvestmentstrategy,ismainlybasedonmodernportfoliotheory,especiallyrepresentedbythemeanvariancemodelofHarryMarkowitz.Thistheoryadvocatesthatinvestorsshou

16、险之间存在线性关系，即资产的风险溢价是其系统风险的函数。指数化投资策略通过复制市场指数，实现了投资组合的系统风险与市场指数相匹配，从而能够享受到与市场指数相一致的预期收益率。TheCapitalAssetPricingTheory(CAPM)alsoprovidestheoreticalsupportforindexbasedinvestments.Capitalassetpricingtheorysuggeststhatinanequilibriummarket,thereisalinearrelationshipbetweentheexpectedreturnofanassetandthe

22、，投资者就需要决定如何复制这个指数。最常见的方法是全额复制，即购买指数中所有成分股，并按照指数权重进行配置。另一种方法是抽样复制，即选择指数中的一部分成分股进行投资，以降低成本和复杂性。Onceanindexisselected,investorsneedtodecidehowtoreplicateit.Themostcommonmethodistofullyreplicate,whichmeanspurchasingallconstituentstocksintheindexandallocatingthemaccordingtoindexweights.Anothermethodissam
