Value at Risk (VaR) estimates potential loss under normal market conditions
Value at Risk (VaR) is a financial metric used to quantify the potential loss in an investment portfolio over a specified time period, given normal market conditions. It helps firms and regulators understand the amount of assets needed to cover possible losses. VaR is typically expressed as a probability (p) and a time horizon, indicating the maximum loss expected with a certain confidence level.
Example
If a portfolio has a one-day 5% VaR of $1 million, it means there is a 0.05 probability that the portfolio will lose $1 million or more in one day, assuming no trading occurs.
Remember this
Understanding VaR helps financial institutions manage risk and ensure they have sufficient capital to cover potential losses.
