J Abstract Two Analytical Approximations of Lecture 7: Value At Risk (VAR) Models Ken Abbott Developed for educational use at MIT and for publication through MIT OpenCourseware. No investment decisions should be Value-at- Risk (VaR) is a general measure of risk developed to equate risk across products and to aggregate risk on a portfolio basis. VaR is defined as the predicted worst-case loss with a specific confidence level (for example, 95%) over a period of time (for example, 1 day).
Risk controlling implies controlling sensitivities to risk by taking offsetting positions to the same risk factors. The size of the hedging position depends on the relative sensitivities of the hedged instruments and the hedging instruments, as it was the case for hedging a risk charge aims to capture the losses on the trading portfolio due issuers of equities and bonds defaulting. Finally, the residual risk add-on is a conservative notional value based add-on mainly for instruments with a non-linear pay-off that cannot be replicated with vanilla options. It aims to capture market risks beyond those Value at Risk (VaR) is the value that is equaled or exceeded the required percentage of times (1, 5, 10). Historical simulation is a non-parametric approach of estimating VaR, i.e. the returns are not subjected to any functional distribution. Estimate VaR directly from the data without deriving parameters or making assumptions about the entire point in time. Value at Risk tries to provide an answer, at least within a reasonable bound. In fact, it is misleading to consider Value at Risk, or VaR as it is widely known, to be an alternative to risk adjusted value and probabilistic approaches. After all, it borrows liberally from both. However, the wide use of VaR as a tool for risk
The presence of non linear instruments is responsible for the emergence of non Gaussian features in the price changes distribution of realistic portfolios, even for Normally distributed risk factors. This is especially true for the benchmark Delta Gamma Normal model, which in general exhibits exponentially damped power law tails. We show how the knowledge of the model characteristic B/abstract.
