This paper investigates whether multivariate crash risk (MCRASH), defined as exposure to extreme realizations of multiple systematic factors, is priced in the cross-section of expected stock returns. We derive an extended linear model with a positive premium for MCRASH and we empirically confirm...

To model the dependence structure between underlying assets we use the …

It is well-known in empirical finance that virtually all asset returns, whether monthly,daily, or intraday, are heavy-tailed and, particularly for stock returns, are mildly but oftensignificantly negatively skewed. However, the tail indices, or maximally existing moments ofthe returns, can...
