Value at risk formula(using the historical method): vm(vi/ v(i - 1)) What is the difference between value at risk (VaR) and standard deviation? Value at risk (VaR) is a measure of the potential loss that an asset, portfolio, or firm might experience over a given period of time.Sta...
Value at Risk = vm(vi/ v(i - 1)) M is the number of days from which historical data is taken, and viis the number of variables on day i. The purpose of the formula is to calculate the percent change of each risk factor for the past 252 trading days. Each percent change is the...

var(value at risk)按字面理解就是“在险价值”,含义是指在市场正常波动下,某一金融资产或证券组合的最大可能损失。更为确切的是指,在一定的概率水平(置信度)下,某一金融资产或证券组合在未来的特定的一段时间内的最大可能损失。用公式可表示为:prob(?驻p>var}=1-a(其中prob表示:资产价值损失小于可能损失上...
Most VaR calculations are not concerned with annual value at risk. The main regulatory and management con- cern is with loss of portfolio value over a much shorter time period (typically several days or perhaps weeks). It is clear that the distribution formula Log[vT ] ~ Normal[ Log[v ]...
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). For...
