金融市场中的连续时间随机游走

The continuous time random walk formalism in financial markets

J. Masoliver, M. Montero, J. Perello, G. H. Weiss

摘要:

我们适应连续时间随机游走(CTRW)形式主义来描述资产价格的演变,并讨论了一些问题,可以使用这种方法来处理。我们主要关注两个方面:(i)从高频数据中推导出价格分布,以及(ii)逆问题,获得仅知道每日波动率的高频数据所反映的市场微观结构信息。我们应用形式主义的金融数据表明,CTRW提供了替代工具来处理金融市场的几个复杂的问题。

英文摘要:

We adapt continuous time random walk (CTRW) formalism to describe asset price evolution and discuss some of the problems that can be treated using this approach. We basically focus on two aspects: (i) the derivation of the price distribution from high-frequency data, and (ii) the inverse problem, obtaining information on the market microstructure as reflected by high-frequency data knowing only the daily volatility. We apply the formalism to financial data to show that the CTRW offers alternative tools to deal with several complex issues of financial markets.
