Normal distribution with mean and standard deviation excel

Calculate the mean of the returns using the average function.Calculate the returns of the closing price Returns = TodayвЂ™s Price - YesterdayвЂ™s Price / YesterdayвЂ™s Price.VaR Calculation in Excel using Variance-Covariance approach For 99% confidence level, VaR is calculated as -2.33 * standard deviation.For 95% confidence level, VaR is calculated as mean -1.65 * standard deviation.We first calculate the mean and standard deviation of the returns.The Variance-covariance is a parametric method which assumes that the returns are normally distributed. LetвЂ™s start with the Variance-Covariance approach. In this blog, we discuss Variance-Covariance approach and Historical Simulation method for VaR calculation. There are various methods that are used for VaR calculation.

In other words, there is only 5% chance that the portfolio losses on a particular day will be greater than 1 million dollar.It implies there is 95% chance that the maximum losses will not exceed 1 million dollar in a single day.Suppose, an analyst says that the 1-day VaR of a portfolio is 1 million dollar, with a 95% confidence level. Holding period may vary from a day to a year. Typically the confidence level lies in the range 90% to 99% such as 90%, 95%, 99%. This definition implies that it is necessary to choose two parameters, namely holding period and confidence level. Value At Risk (VaR) was developed in mid-1990s, in response to the various financial crisis, but the origins of the measures lie further back in time.ДЄccording to Philippe Jorion, вЂњVaR measures the worst expected loss over a given horizon under normal market conditions at a given level of confidenceвЂќ. VaR Calculation using the Historical Simulation approach.VaR Calculation in Excel using Variance-Covariance approach.We'll cover the following about Value At Risk (VaR): We will understand and perform VaR calculation in Excel and Python using Historical Method and Variance-Covariance approach, along with examples. Value at Risk (VaR) tries to provide an answer. What is the most I can lose on an investment? This is the question every investor who has invested asks at some point in time.
