This paper examines the marginal distributions of stocks and bonds, and a copula between the movement of stock prices … risk of an aggregated portfolio, a copula is utilized for risk aggregation, which captures various dependencies in the … median and the tail of marginal distributions, unlike a linear correlation. In this study, various types of copula, including …

Regulatory capital for trading book positions includes two components that cover different risks but apply to the same portfolio, one for market risk and one for credit risk. Similar approaches are common in banks' internal models for economic capital. Although it is known that joint market and...
