Explanation:
The correct answer is C.
Although the overall risk as measured by the tracking error is within the target, the change in risk decomposition indicates a potential "style drift". This is a concern because it might mean the firm is not investing in line with its stated philosophy, which can lead to inconsistent performance and unanticipated risk exposure.
Option A is incorrect because even though the tracking error is within the target, the change in risk decomposition should not be ignored as it might indicate a shift in investment strategy.
Option B is incorrect because the risk decomposition provides additional insights about where and how the risk is being taken. Ignoring this information can lead to a misunderstanding of the firm's risk profile.
Option D is incorrect. While a malfunctioning risk forecasting model can be a concern, the information provided does not necessarily suggest this. The issue here seems more related to the firm's investment activities rather than the performance of the risk forecasting model.
Things to Remember
Tracking error is not only about the total expected deviation from a benchmark but also about the sources of that deviation. Managers should be able to decompose and explain the sources of tracking error.
Risk management requires checking whether the risk taken aligns with the expectations, both at the total and at the constituent levels. If it doesn't, the investment strategy may be deviating from its stated philosophy, a situation often referred to as "style drift."

Q.2538 Chameleon Capital, an investment management firm, has a well-defined and time-tested conviction of focusing on high-quality growth stocks in the US market. According to the recent risk reports, the firm is maintaining the forecasted tracking error consistent with the target established by the mandate. However, the risk decomposition shows that a significant proportion of risk is being taken on non-U.S. instruments, which is unusual for Chameleon Capital. As the Risk Manager of Chameleon Capital, how should you interpret this situation in the context of effective risk monitoring?
A
The situation is not concerning since the firm is maintaining the target tracking error.
B
The risk decomposition is irrelevant as long as the overall risk (tracking error) is within target.
C
There might be a "style drift" in investment activities, indicating a departure from the firm's philosophy.
D
This suggests that the risk forecasting model might not be behaving as predicted.
