Value at Risk (VaR) Estimates for Individual Stocks

In the table below, we report Value at Risk (VaR) estimates for individual stocks over three time frames. The values are based on our volatility forecasts.

Value at Risk estimates how much loss an investment may experience over a specified period of time with a specified degree of probability. One way to phrase the question that VaR seeks to answer is "With 95% confidence, what is the most one would expect investment to lose over the next week (or month, or year)?"

We report 5% VaR estimates in percentage terms. For example a stock with a VaR of 10% over the next month has an estimated 5% probability of losing 10% or more. Put differently, there is a 95% estimated probability that the stock would not lose more than 10% of its value.

Value at Risk measures have several known limitations. Positions can and do lose more than stated VaR values, and the misuse of VaR by financial institutions has been implicated in the 2008 financial crisis. We publish the our value at risk measures as a rough guide to the riskiness of individual stocks projected from recent market conditions. We update this report at the end of each week.
