Var Marginal

Hello,

Please help me for the below question:

  1. Consider a two asset portfolio. The portfolio weight of asset A is 0.6 and the portfolio weight of asset B is 0.4 . The value of the total portfolio is 1 million and standard deviation of its decimal return is 0.060606. If the Betas of Asset A and asset B are 0.8 and 1.3 repectively, the repective marginal Var of Asset A and the component Var of Asset B at 95% confidenve level are closest to: a. USD 0.80 and USD 52,000 b. USD 0.80 and USD 48,000 c. USD 0.08 and USD 52,000 d. USD 0.08 and USD 48,000 Thanks, Vishal

Hello Srishti,

Thanks for the reply!!

Can you please tell me the steps for the same?

Thanks in advance.

Vishal;

I simply put values in the formulae, shown below

Pf VaR = z* Std Dev * Pf value

1.65*0.060606*1,000,000=99,999.9 100,000

MVAR Asset A = (VAR (Pf)/ Pf Value) *Beta

= (100,000/1,000,000) * 0.8=0.08

Component Var for Asset B = Mvar (B) * Wt of B * Pf Value

= [(VAR (Pf)/ Pf Value) *Beta] * Wt of B * Pf Value

= Var Pf *Beta * Wt of Asset B

= 100000* 1.3* 0.4 = 52000

Hope this helps, coz its quite an effort to type out all this :expressionless:

Thanks a lot Shristi!!
