Value at Risk (VaR)

Value at Risk is the most popular estimation technique used by mutual funds, hedge funds, banks and insurance companies to determine how much money they can expect to lose if the stock market declines. The same Value at Risk models used by managers of billions of dollars can help small investors manage their 401(k) accounts.

VaR is a tool to quantify expected worst-case losses. In other words, Value at Risk software can answer the question, “What is the most I should expect to lose over the next month, with a 95 percent or 99 percent confidence level?” VaR software is commonly used to calculate possible losses from exposure to the stock market. But, the VaR concepts are versatile enough to be used to find potential portfolio losses associated with changes in interest rates, currency fluctuations or any other risk factor. VaR facts you need to know:

Value at Risk models use past returns to estimate the future likelihood of losses.
Complex mathematical principles are required to calculate VaR, but you don’t need to understand the math to benefit from Value at Risk models.
Trading strategies can minimize Value at Risk, but first the portfolio VaR must be defined.

Move beyond Value at Risk to fully analyze portfolio risk

Value at Risk is only one component of portfolio risk. Interest rates can move rapidly and cause losses in fixed income instruments. Companies that import or export (nearly all large companies) are at risk if currencies move too far, too fast. Among other risks a portfolio can face are rising energy prices, which have led to recessions in the past. Today's investment environment is complex, and risk management is a never-ending process.
Try: After implementing Value at Risk into the management process, take advantage of training options to learn about interest rate risk, managing currencies exposure and lessening the risk associated with the cost of energy.

Tips & Advice to help you make your decision on Value at Risk (VaR)

Value at Risk (VaR) is a way of measuring risk, and is used in financial risk management. It measures the specific risk of loss on a range of financial assets. VaR is based on a portfolio, a probability of an extreme loss occurring, and a time horizon. An example is that a specific portfolio can have a one-day 1% VaR of $2 million, meaning there is a 0.01 probability that the portfolio could fall in value by $2 million in a one day trading period.
