Gibson incorporates event risk into VaR for a portfolio. . dollars relative to the end-of-period expected asset value (relative VaR) Kupiec ([9, page 43]) demonstrates that the absolute VaR is more View at Google Scholar; B. E. Hansen, “The new econometrics of structural change: dating breaks in U.S. Value at risk relative absolute dating. In epidemiology, relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the.

The relative difference is the ratio of the two risks. Given the data above, the relative difference is: A good example of reporting risks In our review of a STAT story on new aspirin guidelines, we praised them for using both absolute and relative numbers. In a meta-analysis of the six major randomized trials of aspirin for primary prevention, among more than 95, participants, serious cardiovascular events occurred in 0.
That corresponds to a 20 percent relative reduction in risk. At the same time, serious bleeding events increased from 0.
In addition, it would have been even more informative for the STAT story to express the absolute percentages as a rate — e. The relative numbers make the increase bleeds look bigger than the reduction in cardiovascular events, but expressing the numbers as an absolute rate makes it clear that the reduction in events was larger. The release points out that those study participants whose blood pressure goal was mm of mercury had 33 percent fewer cardiovascular events, such as heart attacks or heart failure, and had a 32 percent reduction in the risk of death, compared to those participants with a higher goal.
VaR: Exchange Rate Risk and Jump Risk
It should be noted that these relative reductions correspond with absolute risk reductions of only about 0. In other words, approximately people need to be treated to this target in order for 1 person to experience an improved outcome. The problem often starts at the research level While absolute numbers are essential, they also may be hard to find.
Thus, exchange rate risk should be considered in high international investment. This paper aims to present analytical VaRs of a portfolio including domestic-issued and foreign-issued assets. Using the framework provided by Merton [ 7 ], we employ return jumps at the Poisson arrivals to avoid the assumption of normality of asset returns.
Also, the Brownian motions of between-jump returns are correlated. An analytical formula of the VaR is then derived. In general, the solution is more accurate than nonparametric techniques often adopted in fat-tail distributions in terms of the system infrastructure and computation time. In addition, this model can be also applied to large portfolios.

Compared with that of Hofmann and Platen [ 1 ] and Guan et al. This model is more suitable for the global capital markets.
The rest of this paper is organized as follows. The next section outlines the model, and an analytic formula of the value at risk is derived. In the third section, a comparative static analysis on the risk capital measured by the VaR approach is provided. The samples in this study span from January 1, to November 27,or daily log returns of a line of stock prices and stock indices.
The last section provides conclusions. Model Formulation First, this paper assumes the following: The dynamic processes of asset price and exchange rates are demonstrated as follows, respectively, where, and denote constant drift rates of domestic asset returns, foreign asset returns and exchange rate returns for eachrespectively;, and stand for constant volatilities of domestic asset returns, foreign asset returns and exchange rate returns for eachrespectively.
The are one-dimensional Brownian motions defined in a filtered probability space under the original probability measure, for all. Also, the correlation coefficients among the three Brownian motions are defined as .
