Answer: Stressed VaR is not necessarily based on data from the immediately preceding period, unlike traditional VaR.

## Explanation **Correct Answer: D** **Analysis:** **Traditional VaR vs. Stressed VaR:** - **Traditional VaR**: Typically uses data from the immediately preceding period (e.g., 1-4 years) to estimate risk parameters - **Stressed VaR**: Uses data from a specific stress period in the past (not necessarily the most recent period) that represents significant market turmoil **Key Differences:** - **Data Period**: Stressed VaR uses historical data from a specific stress period, while traditional VaR uses recent historical data - **Purpose**: Stressed VaR aims to capture risk during extreme market conditions, while traditional VaR reflects normal market conditions - **Regulatory Requirements**: Basel III requires banks to calculate both traditional VaR and stressed VaR **Why other options are incorrect:** - **A**: Both VaR measures can be based on conditional or unconditional distributions - **B**: Both typically use similar time horizons (usually 10-day holding period) - **C**: Both generally use similar probability distribution assumptions
