Value at Risk Framework or VAR framework is mainly used for financial risk management or financial mathematics in measuring the risk element on a definite portfolio of financial assets, present in any economic organization. This particular portfolio comprises of time event and probability, which states the threshold of the risk loss value over the period of time. These risk loss values are assumed to be according to the market to market pricing, no trading and normal market which contributes in this
minimizing the portfolio VAR while keeping the portfolio fully invested. The first tool for risk management is the marginal VAR which used to measure the effect of changing positions on portfolio risk. It measure the marginal contribution to risk by increasing w by a small amount. Therefore, Marginal VAR (value at risk) allows risk managers to study the effects of adding or subtracting positions from an investment portfolio. Since value at risk is affected by the correlation of investment
necessity of further researches on hedge funds’ capital adequacy. In 2000, Fung and Hsieh used a mean-variance approach to study hedge fund exposures in some major market events. They analysed hedge fund performance during turbulent market times. But due to limitations of their research methodology, they
economic growth using time series modeling. For each of the four case-countries three types of Vector Autoregression (VAR) models will be developed except for the case of Serbia where only VAR related to credit institutions development will be developed since data related to stock market development indicators were unavailable to author. For the case of Croatia, Slovenia and China three separate VAR models will be applied. First, bivariate VAR model to explore the connection between credit institutions
This study employs the adjusted price of GBP exchange rates for 12 different currencies where BNKR’s investments are dominated in, during the period of January 2010 till July 2015. The total number of daily logarithmic returns of each exchange rate is 1455. The daily logarithmic return is defined as: R_t=ln*((P_t-P_(t-1))/P_(t-1) ) Where P_t is the adjusted spot exchange rate at time t. The descriptive statistics summary of daily logarithmic returns is reported in Table 1. Therefore, assessing the

to be able to cover the potential loss. Although the term “Value at risk” has not been used till the1990s, the origins of its measure lie further back in time. The arithmetic behind the VaR were developed by Harry Markowitz (1952) in his studies of effects of asset risk, return, correlation, and diversification on probable investment portfolio returns which contributed to the modern portfolio theory. In fact, the trigger of the use of VaR came from the crisis that tormented the financial market and
Copula to Estimate Value at Risk ActSc 991 Project Changwu (Allen) Chen April 14, 2014 1 1 Introduction Value at Risk (VaR) plays a central role in risk management. By definition, VaR is the maximum expected loss of a portfolio over a given time horizon with a certain confidence level. VaR can be seen as a quantile on the lower tail of the distribution of portfolio returns. Although VaR is a simple measure, it is not easily estimated. There are several approaches for the estimation of VaR, such as historical
The Value at Risk, commonly known as VaR, tries to answer this question within a reasonable bound. VaR is used in financial mathematics and financial risk management as a risk management tool to measure the risk of loss of an individual asset or a whole portfolio. Although it provides a good sense of risk one is undertaking, it shouldn’t be an alternative method to risk adjusted value and or other probabilistic approaches. In the following lines, we first give a general description of the VaR and
