    Abstract: 近年來風險值已成為風險管理的新方法。有眾多的文獻在探討投資組合風險值,提供投資人在所持有的投資組合中,未來可能承受的最大損失,進而加強對投資組合之風險控管。
    Value at Risk(VaR) is very important in risk management. There are numerous articles and theses focus on VAR at investment portfolios in order to provide further understanding in the possible losses that the investors may endure in the future and therefore to strengthen the risk control and management on the portfolios.

    This paper adopts the multivariate GARCH model to obtain conditional variations about the portfolios. We also incorporates the weighted adjustments of the portfolios on Taiwan stock market index, Taiwan and US. Exchange rate, and crude oil futures to the model to analyze the portfolio variation of equal weight and unequal-weighted allocation based on the same returns. The model in several related articles usually adopts equal weights allocation portfolios to estimate VaR, however the accuracy and rationality of those models are questionable.

    The result shows that allocate the portfolios at the optimized weight has less variation than at equal weight, that is, the portfolios at optimized weight allocation has less volatility compared to equal-weighted allocation portfolios at the same return level, implying that the portfolios at the optimized weight allocation should be a better investment strategy.
