摘要

本研究通过采用动态条件方差和动态条件协方差对一些选定的新兴市场和发达市场的最优对冲投资组合进行了检验。在整个研究中,我们使用了一些选定的投资工具的每日指数值。数据范围为2006年2月1日至2018年11月1日。在本文中,为了获得每个新兴国家最有效的对冲投资组合,我们首先使用dc - figarch规范来衡量波动率。其次,我们通过观察模型的预测性能来检验模型的稳健性。由于样本外预测性能能够以详细的方式协助离群值和数据挖掘的经验证据,并且它更好地反映了预测者在“实时”样本外预测中可获得的信息,因此更适合用于这方面。然后,我们计算平均绝对误差(MAE)来检测最拟合的模型。第三,我们提出了两种方法:最优对冲比率和最优投资组合权重。这些方法对对冲投资组合有两个启示。最后,我们将提出结果背后的经济原理。

Optimal Dynamic Hedging in Selected Markets
This study examines the most optimal hedging portfolio for some selected emerging and developed markets by employing dynamic conditional variances and dynamic conditional covariances. Throughout the study, we used the daily index values of some selected investment instruments. The data contains the period from 02/01/2006 to 01/11/2018. In this essay, to obtain the most efficient hedging portfolio for each emerging country, firstly, we used Dcc-Figarch specifications to measure volatility. Secondly, we checked the robustness of the model by observing its forecast performance. As out-of-sample forecast performance has an ability to assist empirical evidence to outliers and data mining in a detailed way as well as it reflects better the information available to the forecaster in “real-time” out-of-sample forecasting is more appropriate to be used in this regard. Then, we calculated the mean absolute error (MAE) to detect the most fitted model. Thirdly, we mentioned two methods: Optimal hedge ratio and optimal portfolio weight. These methods are two hedging portfolio implications. Lastly, we will propose an economic rationale behind the results.
