摘要: This note analytically derives lower and upper bounds for Value-at-Risk and convex risk measures of a portfolio of weighted risks in the context of positive dependence.The bounds serve as extensions of the corresponding ones due to Bignozzi et al.(2015).Also, DUspread of value-at-risk and expected shortfall of Bignozzi et al.(2015) are also improved in some particular cases.
