The 5% Value at Risk of a hypothetical profit-and-loss probability density function. Value at risk (VaR) is a measure of the risk of loss of investment/capital.It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day.
Historical simulation in finance's value at risk (VaR) analysis is a procedure for predicting the value at risk by 'simulating' or constructing the cumulative distribution function (CDF) of assets returns over time assuming that future returns will be directly sampled from past returns.
A typical application of VaR is in investment banking, where the bank holds economic “risk capital” corresponding to the estimated number; see Financial risk management § Banking. VaR is also used in portfolio risk management, where, as above, simulation allows the fund manager to estimate losses at a given horizon and confidence level ...
An immediate consequence is that value at risk might discourage diversification. [1] Value at risk is, however, coherent, under the assumption of elliptically distributed losses (e.g. normally distributed) when the portfolio value is a linear function of the asset prices. However, in this case the value at risk becomes equivalent to a mean ...
Assembling portfolio assets is a highly personal decision for each investor, one that should be based on short-term goals, long-term goals, risk tolerance, and any other financial needs you may have.
Financial risk modeling is the use of formal mathematical and econometric techniques to measure, monitor and control the market risk, credit risk, and operational risk on a firm's balance sheet, on a bank's accounting ledger of tradeable financial assets, or of a fund manager's portfolio value; see Financial risk management.
