What is a key disadvantage of stress testing in finance?

1. It universally factors in all types of risks.

2. It often does not properly aggregate results.

3. It always provides overly conservative estimates.

4. It limits the scope of financial instruments being tested.

The correct answer is: It often does not properly aggregate results.

A key disadvantage of stress testing in finance relates to the aggregation of results. While stress testing is designed to assess how financial institutions might perform under adverse economic conditions, one of the common pitfalls is the potential for improper aggregation of the results. This can lead to an inaccurate representation of risk exposure, as the individual stress tests for various scenarios or factors may not correlate correctly when combined. For instance, stress tests often focus on specific asset classes or risk categories, and the aggregated outputs might not reflect the true risk profile of the institution, failing to account for interdependencies or correlations between different types of risks. When results are not properly aggregated, it can provide a misleading view of overall risk, leading to inadequate risk management measures or responses by financial institutions. Other considerations like overly conservative estimates or limitations on the types of instruments tested also exist, but they do not directly speak to the aggregation issue, which fundamentally undermines the reliability of the stress testing outcomes. Therefore, the improper aggregation of results is a significant disadvantage that can result in misguided decisions based on the test findings.
