In other words, t’s a minimum loss in dollars over a given period based on probability of past performance.
2019-11-27 · Figure 1: Inputs – Fixed Income Bond Var. Security specification. To build the model we will calculate interest rate value at risk (Rate VaR), bond price value at risk (Price VaR) as well as the delta normal approximation which translates rate VaR into price VaR by using modified duration.
In fact, it is misleading to consider Value at Risk, or VaR as it is widely known, to be an alternative to risk adjusted value and probabilistic approaches. After all, it borrows liberally from both. However, the wide use of VaR as a tool for risk Value at risk (lub wartość zagrożona ryzykiem) – miara ryzyka wyrażająca graniczny poziom straty znaleziony dla ustalonego , będącego prawdopodobieństwem jej osiągnięcia.

Il valore a rischio è una misura di rischio applicata agli investimenti finanziari. Tale misura indica la perdita potenziale di una posizione di investimento in un certo orizzonte temporale, solitamente 1 giorno, con un certo livello di confidenza, solitamente pari al 95% o 99%. È una tecnica comunemente usata da banche d'investimento per misurare il rischio di mercato delle attività che detengono in portafoglio, ma è anche un concetto più vasto che ha molteplici applicazioni. VaR(Value at Risk)按字面解释就是“在险价值”，其含义指：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，在一定概率水平（置信度）下，某一金融资产或证券组合价值在未来特定时期内的最大可能损失。
Value-at-risk metrics require larger samples. For 90%value-at-risk or 99%value-at-risk, consider sample sizes of 30,000 or 45,000, respectively. Even if a portfolio mapping function θ is simple, performing such large numbers of valuations can be computationally expensive.

Abstract The value at risk (VaR) measures the risk of loss associated to financial assets. In the case in which a bank does not have models for VaR calculation
This confusion complicates its use, due to challenges such as governance, development of organizational capabilities, and the implementation of tools. For a given time period and probability, a value-at-risk measure purports to indicate an amount of money such that there is that probability of the portfolio not losing more than that amount of money over that time period. If the two positions were perfectly correlated with r =1, the VARs would simply have been additive. That means the 7 day value at risk would have been 132.95 (from 96.02+36.93) and not 124.69. The 1 day VAR would be 50.25 and not 47.12.
Value at Risk gives the probability of losing more than a given amount in a given portfolio. Value at risk is a measure of the risk of loss for investments. It estimates how much a set of investments might lose, given normal market conditions, in a set time period such as a day. VaR is typically used by firms and regulators in the financial industry to gauge the amount of assets needed to cover possible losses. For a given portfolio, time horizon, and probability p, the p VaR can be defined informally as the maximum possible loss during that time after excluding all worse outcomes whose Value-at-risk (VAR) Value-at-risk is a statistical measure of the riskiness of financial entities or portfolios of assets.
