estimation of value-at-risk with time varying skewness and kurtosis
this paper studies the effect of considering time varying skewness and kurtosis on the estimation of value at risk (var) for both long and short positions using the hyaparch model and daily data for tehran stock exchange price index (tepix). our results show that applying conditional distributions with time varying or constant skewness and degrees of freedom is able to capture the asymmetry app...
متن کاملHarmonic Analysis in Value at Risk Calculations
Value at Risk is a measure of risk exposure of a portfolio and is de ned as the maximum possible loss in a certain time frame, typically 1-20 days, and within a certain con dence, typically 95%. Full valuation of a portfolio under a large number of scenarios is a lengthy process. To speed it up, one can make use of the total delta vector and the total gamma matrix of a portfolio and compute a G...
متن کاملUsing copulae to bound the Value-at-Risk for functions of dependent risks
The theory of copulae is known to provide a useful tool for modelling dependence in integrated risk management. In the present paper we review and extend some of the more recent results for finding distributional bounds for functions of dependent risks. As an example, the main emphasis is put on Value-at-Risk as a risk measure.
متن کاملValue at Risk Calculations, Extreme Events, and Tail Estimation
THE JOURNAL OF DERIVATIVES 1 The notion of extreme movements in asset prices is implicit in current risk management practices. Capital adequacy assumes a threshold that classifies observed changes in market risk factors either as extreme or ordinary. A probability is first chosen to measure the “extremeness” of events that may affect a particular portfolio. This probability then determines the ...
متن کاملconditional copula-garch methods for value at risk of portfolio: the case of tehran stock exchange market
ارزش در معرض ریسک یکی از مهمترین معیارهای اندازه گیری ریسک در بنگاه های اقتصادی می باشد. برآورد دقیق ارزش در معرض ریسک موضوع بسیارمهمی می باشد و انحراف از آن می تواند موجب ورشکستگی و یا عدم تخصیص بهینه منابع یک بنگاه گردد. هدف اصلی این مطالعه بررسی کارایی روش copula-garch شرطی در برآورد ارزش در معرض ریسک پرتفویی متشکل از دو سهام می باشد و ارزش در معرض ریسک بدست آمده با روشهای سنتی برآورد ارزش د...
