Consider the primary methods of assessing the risk of a portfolio position through stress testing.  Which of the following does not accurately describe an advantage or disadvantage related to a stress testing method?
　　A. A disadvantage to the historical simulation approach is that it is limited to historical data which may be inappropriate in future periods.
　　B. An advantage of the historical crisis approach is that it requires no assumptions regarding the underlying distribution of portfolio returns.
　　C. A disadvantage to the stress scenario analysis method is that it can produce misleading risk measures.
　　D. An advantage to the stress scenario analysis method is that it accounts for asset-class-specific risk factors.
　　Answer:D
　　The stress scenario analysis method analyzes varying predetermined stress scenario to determine the effect on the current portfolio.  The advantage of this approach is that it is not limited to historical events.  Disadvantages include its inability to account for asset-class-specific risk factors and its tendency to produce deceptive risk measures.
