英文摘要:
Drawdowns measuring the decline in value from the historical running maxima over a given period of time, are considered as extremal events from the standpoint of risk management. To date, research on the topic has mainly focus on the side of severity by studying the first drawdown over certain pre-specified size. In this paper, we extend the discussion by investigating the frequency of drawdowns, and some of their inherent characteristics. We consider two types of drawdown time sequences depending on whether a historical running maximum {is reset or not}. For each type, we study the frequency rate of drawdowns, the Laplace transform of the $n$-th drawdown time, the distribution of the running maximum and the value process at the $n$-th drawdown time, as well as some other quantities of interest. Interesting relationships between these two drawdown time sequences are also established. Finally, insurance policies protecting against the risk of frequent drawdowns are also proposed and priced.

中文摘要:
从风险管理的角度来看,从给定时间段的历史运行最大值衡量价值下降的支取被视为极端事件。到目前为止,关于这一主题的研究主要集中在严重性方面,通过研究特定预先规定规模的首次下降。在本文中,我们通过调查提取频率及其一些固有特征来扩展讨论。根据历史运行最大值{是否重置},我们考虑两种类型的下降时间序列。对于每种类型,我们研究了提款的频率、第n$次提款时间的拉普拉斯变换、运行最大值的分布、第n$次提款时间的价值过程,以及其他一些感兴趣的数量。这两个下降时间序列之间也建立了有趣的关系。最后,还提出并定价了针对频繁提款风险的保单。
