【摘要】:以國(guó)際套利定價(jià)理論為基礎(chǔ)并對(duì)其進(jìn)行拓展,構(gòu)建了國(guó)際多因素模型。揭示國(guó)際組合套利行為的內(nèi)在機(jī)理為:通過構(gòu)建組合,對(duì)沖掉降低資產(chǎn)相關(guān)性的因素,或者增加能提高資產(chǎn)相關(guān)性的因素,實(shí)現(xiàn)用于套利的資產(chǎn)匹配。使用傳統(tǒng)的均值-方差法求解出優(yōu)化結(jié)果,并分析其缺陷所在。提出一種新的計(jì)算頭寸比例的改進(jìn)方法,即以資產(chǎn)相關(guān)性強(qiáng)弱作為構(gòu)建套利組合的基本標(biāo)準(zhǔn),采用資產(chǎn)組合復(fù)制技術(shù),通過計(jì)算機(jī)程序?qū)M合中各資產(chǎn)的價(jià)格時(shí)間序列進(jìn)行預(yù)處理,再進(jìn)行噪聲清理和歸一化處理后,得出優(yōu)化的國(guó)際組合套利頭寸比例,并以全球主要資本市場(chǎng)的指數(shù)作為研究對(duì)象進(jìn)行實(shí)證分析。
[Abstract]:Based on the international arbitrage pricing theory, the international multi-factor model is constructed.The intrinsic mechanism of international portfolio arbitrage behavior is to hedge the factors that reduce the asset correlation by constructing the portfolio or to increase the factors that can improve the asset correlation so as to realize the asset matching for arbitrage.The traditional mean-variance method is used to solve the optimization results and its defects are analyzed.In this paper, a new method to calculate the position ratio is proposed, that is, the asset correlation is taken as the basic criterion for constructing arbitrage portfolio, and the portfolio replication technique is adopted.The price time series of each asset in the portfolio are pretreated by computer program, then the noise is cleaned up and normalized, and the optimized arbitrage position ratio of international portfolio is obtained.And take the index of the main capital market as the research object to carry on the empirical analysis.
