    Abstract: 如何建構績效良好的投資組合一直是學界以及業界不斷研究的議題。以財務理論上來說,平均數-變異數投資組合法可說是建構投資組合一個基本的方法,但實際上它的表現受到諸多限制。例如當資產數目增加的情況下,平均數-變異數投資組合法需要估計的模型參數會大幅增加,間接地估計誤差也跟著上升。本文使用範數懲罰函數,結合平均數-變異數投資組合法,來建構最小變異數投資組合。本文以全球股市為標的,利用擴大視窗的方式估計出最小變異數投資組合之權重,以建構最小變異數投資組合,並比較其他不同投資組合的績效表現,探討最小變異數投資組合在資產數目增加的情況下,施加範數懲罰函數後,是否較不施加任何限制之投資組合為更有效率的投資組合。
