Answer: Stress testing makes it possible to capture dependencies between asset classes in specific scenarios that cannot be captured well through a VaR-based system.
## Explanation **Correct Answer: B** Stress testing complements VaR systems by capturing dependencies between asset classes in specific scenarios that VaR may not adequately capture. VaR typically relies on historical data and statistical distributions, while stress testing allows for the examination of extreme but plausible scenarios where correlations between asset classes may change dramatically. **Why other options are incorrect:** - **A**: This is inaccurate because VaR systems can use many scenarios (especially Monte Carlo VaR), and stress tests often focus on a limited number of extreme but plausible scenarios. - **C**: Stress testing is not necessarily more accurate in predicting probability of losses; it focuses on extreme scenarios rather than probabilistic estimates. - **D**: Stress testing is not restricted to macroeconomic variables; it can include various risk factors including market, credit, liquidity, and operational risks.

A manager at an asset management firm relies on a VaR-based risk measurement system that calculates VaR for each of the firm's portfolios as well as an aggregate firm-wide VaR. The CRO proposes implementation of a stress testing approach to supplement the VaR system. Which of the following statements best supports the CRO's proposal?
A
In practice, stress tests utilize a great number of scenarios while VaR measures rely on just a few scenarios to create their loss estimates.
B
Stress testing makes it possible to capture dependencies between asset classes in specific scenarios that cannot be captured well through a VaR-based system.
C
Stress testing is more accurate than a VaR-based system in predicting the probability of losses at a point in time.
D
While stress testing is similar to VaR, it is restricted to using only distributions of macroeconomic variables to generate its predictions.
