摘要

SIAM 金融数学期刊》，第 15 卷第 1 期，第 295-314 页，2024 年 3 月。摘要。我们研究的是均值风险最优投资组合问题，其中风险由回收平均风险值衡量，这是回收风险度量类中的一个突出例子。我们在已知投资组合资产联合分布的情况下，以及在投资组合资产联合分布不确定且仅假定属于基准分布的一组混合物（混合物不确定性）或基准分布周围的一团云（盒状不确定性）的情况下，建立了存在结果。与传统的风险平均值比较表明，在其回收版本下的投资组合选择能使金融机构更好地控制负债的回收，同时仍能进行简便的计算。

Robust Portfolio Selection under Recovery Average Value at Risk

SIAM Journal on Financial Mathematics, Volume 15, Issue 1, Page 295-314, March 2024.
Abstract. We study mean-risk optimal portfolio problems where risk is measured by recovery average value at risk, a prominent example in the class of recovery risk measures. We establish existence results in the situation where the joint distribution of portfolio assets is known as well as in the situation where it is uncertain and only assumed to belong to a set of mixtures of benchmark distributions (mixture uncertainty) or to a cloud around a benchmark distribution (box uncertainty). The comparison with the classical average value at risk shows that portfolio selection under its recovery version enables financial institutions to exert better control on the recovery on liabilities while still allowing for tractable computations.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
