[R-SIG-Finance] Portfolio VaR and Asset VaR

Hi again,

Let say I have a diversified portfolio of 5 assets. The individual
Asset VaRs for them are $A, $B, $C, $D, & $E. And the overall
portfolio VaR is $P. Assumed all VaR numbers are reported in absolute

It appears that P is less than all 5 individual VaRs.

Can that happen? I know that P < (A+B+C+D+E). However here in my
calculation what happened is P is less than each asset VaR.

Appreciate your view.

Thanks and regards,
