MARGINAL VAR

Additional value of risk a new investment position that is added to an investment portfolio. Marginal Value at Risk (VaR) lets risk managers to study how adding or subtracting positions affect a portfolio. Since VaR is moved by the correlation of positions, this is not sufficient to consider a person investment’s VaR level in isolation; but rather be compared with the total portfolio in order to figure out what contribution makes the portfolio’s VaR amount.
