What is Value at Risk and how is it used?

March 7th, 2003, 7:59 pm

Value at risk Var is generally understood to mean the maximum loss an investment could incur at a given confidence level over a specified time horizon. The concept of Var was introduced as innovation in risk measure and is a simpler riexposure of a commonly used metric risk exposure. It’s a likelihood of loss given a confidence interval:a.You specify an expected return from assets included in a specified portfoliob.You define a standard deviationc.You estimate the probability that the total portfolio would incur in a given loss for istance of 20% What about Var limits and substition and usefulness of Expected Shortfall?

"What is Value at Risk and how is it used"So far there has been a good discussion about what VaR is, but not much about how it is used. How should it be used? (Other than allocating trading limits among traders/teams, which has been mentioned). Increase exposure when VaR is low, decrease when high? (Looks to me like this has historically been a terrible idea) If not that, what else?
