摘要:   本論文提出數個線性規劃模型建立投資組合。這些模型所採用的風險函數為報酬率之絕對值,而不是一般常用的報酬變異數,並且只針對下層風險的部分加以考量。在給定的報酬水準以及考量投資標的的表現之下,此模型尋找在觀察期間內風險最小的投資組合。同時我們考慮追蹤標的指數及資料時間遠近對投資組合的影響,並以臺灣發行量加權股價做為實證的對象。實證數據顯示,依照我們提出的模型所建立的投資組合,其表現均較標的指數為佳。
  Several linear programs for selecting portfolio based on historical return are proposed. These models use the downside risk rather than the variance as a risk measure. The portfolio is chosen based on miniming the downside risk over all past observation periods to reach a given return level. The models involve the tracking index or the history effect of return data in the construction of portfolio are also presented. The computational results are illustrated with the real data from the Taiwan stock market. The performance of the resulting portfolios is better than the index of Taiwan stock market.
