1. ### Calculating Value at Risk need help

Hey for school i have to calculate the VaR but I am unable to find the right calculation, can anyone help me solve it? "Suppose an investor wants to take 500 shares of Tesla in a pre-portfolio. The price is \$ 800.00 per share The term of this position is 1 day. The daily volatility is: 2%...
2. ### YouTube T5-05: Value (VaR) Mapping a fixed-income portfolio

In this video, we walk through an actual case study of Value at Risk (VaR) mapping, specifically as it is illustrated by Phillip Jorion in Chapter 11 of his book, Value at Risk. We will take a two-bond fixed income portfolio. It's going to have a value of 200 million, and we're going to look at...
3. ### YouTube T5-04: Value at Risk (VaR) Backtest

When we specify something like a 95% value at risk or 95% VaR, we mean that 95% is the confidence level and, therefore, 5% is the significance level. That means we expect on 5% of days for the actual loss to be worse than the VaR or to exceed the VaR. This video is about the backtest of a VaR...

Value-at-Risk Models forms part four of the Market Risk Analysis four-volume set. Building on the three previous volumes this book provides by far the most comprehensive, rigorous and detailed treatment of market VaR models. It rests on the basic knowledge of financial mathematics and statistics...
5. ### YouTube T4-01: Three approaches to value at risk (VaR) and volatility

The three approaches are 1. Parametric; aka, analytical; 2. Historical simulation; and 3. Monte Carlo simulation (MCS). The parametric approach assumes a clean function, the other two work with messy data. Historical simulation is betrayed by a histogram, MCS is betrayed by a random number...
6. ### YouTube T1-5 What is the (Basic) Historical Simulation approach to value at risk (VaR)?

Basic historical simulation sorts the actual loss history and, for example, the 95th HS VaR is the 6th worst out of 100 observations. Here is David's XLS: http://trtl.bz/frm-t1-5-hs-var
7. ### YouTube T1-2 What is value at risk (VaR)?

Value is risk is just a statistical feature of probability distribution (the hard part is specifying the probability distribution): VaR is the quantile associated with a selected probability; i.e., what's the worst that can happen with some level of confidence? See David's XLS here...
