Subadditivity Re-Examined: the Case for Value-at-Risk

Jon Danielsson, Casper de Vries, Bjorn Jorgensen, Gennady Samorodnitsky and Sarma Mandira
November 2005

This paper explores the potential for violations of VaR subadditivity both theoretically and by simulations, and finds that for most practical applications VaR is subadditive. Hence, there is no reason to choose a more complicated risk measure than VaR, solely for reasons of coherence.
