Secondly, there are bigger value at risk by Historical Simulation Method of risk-factors free, represented investitive net value are NT 10,000,000, maximum loss of 5﹪probability will greater than NT 2,816,827 or NT 2,344,946. So used considering VAR－Bootstrap of risk factors were more appropriated model, because model of considering risk factors were able to accurate estimate reality value at risk.

二、以未考量风险因子之历史模拟法及GARCH－拔靴法所估计风险值较大，表示投资净值一千万，有5﹪的机率可能的最大损失会大於2，816，827元或2，344，946元，因此，考量风险因子之VAR模型－拔靴法为较适当之模型，因有考量影响风险之因子，较能准确估计出实际之风险值。
