AI总结:

本文定义了一类利用交易期内开盘价、收盘价、最低价和最高价来推断资产价格波动率动态的随机波动率模型,并通过序贯蒙特卡洛算法进行拟合,与文献中已有模型比较,用模拟和SP500指数数据验证了其有效性。

摘要:

越来越多的经验证据表明,交易期内观察到的极端价格可以提供关于该时期内过程波动率的有价值信息。在本文中,我们定义了一类随机波动率模型,该模型利用交易期内的开盘价和收盘价以及最低价和最高价来推断资产价格波动率过程的动态,并与文献中先前提出的类似模型进行比较。本文还讨论了拟合这类模型的序贯蒙特卡洛算法,并通过模拟研究和SP500指数数据说明了其特征。

英文摘要:

Mounting empirical evidence suggests that the observed extreme prices within a trading period can provide valuable information about the volatility of the process within that period. In this paper we define a class of stochastic volatility models that uses opening and closing prices along with the minimum and maximum prices within a trading period to infer the dynamics underlying the volatility process of asset prices and compares it with similar models that have been previously presented in the literature. The paper also discusses sequential Monte Carlo algorithms to fit this class of models and illustrates its features using both a simulation study and data form the SP500 index.
