I am using a structural VAR model with sign restrictions and three structural shocks to model the oil price. I estimated the historical decomposition (using sign restriction approach by uhlig) and I have used dlog (oilprice) in my VAR. coldlok lunch bag

Calculating Value at Risk (VaR) of a Stock Portfolio using Python

WebbVaR (Value at Risk) was developed in the early 90s as a financial risk management tool. In 1994, J.P Morgan's asset risk management department provided the VaR method to the world. At that time, the world does not have a consistent risk management standard. VaR is reasonable in theory, and in practice, so it was quickly paid an WebbInvestigating how well each of these methods (HS and FHS) works in VaR measurement field is the main purpose of this thesis.

WebbFrom historical data, we find that the worst increase in yields over a month at the 95% is 0.40%. The worst loss, or VAR, is then given by Worst Dollar Loss = Duration x 1/(1+y) x Portfolio Value x Worst Yield Increase VAR = 4.5 Years x (1/1.05) x $100m x 0.4% which is also $1.7 million!

Market conditions and currency devaluations may have occurred, dramatically shifting time series relationships. Also, high confidence levels (i.e., 99% and beyond) are coarse. For example, if ...

WebbFiltered Historical Simulation VaR can be described as being a mixture of the historical simulation and EWMA methods. Returns are first standardized, with volatility estimation weighted as in EWMA VaR, before a historical percentile is applied to the standardized return as in the historical model. From the graphs it is easy to spot that WebbThis method is based on the assumption that history would repeat itself. 2. Parametric method. The most common way of calculating VaR is the parametric method, also known as variance covariance method. This method assumes that the return of the portfolio is normally distributed and can be completely described by expected return and standard ...
