What is cross-sectional momentum defined as in the context of financial securities?

• A. Performance relative to a market index
• B. Absolute performance over time
• C. Performance based on peer comparison
• D. Market volatility comparison

Answer: (C)

Cross-sectional momentum refers to the phenomenon where the performance of a security or asset is evaluated relative to the performance of its peers at a specific point in time. In finance, this often involves analyzing returns from a group of similar securities or assets to identify those that are performing better or worse relative to the others. The notion is that securities that have outperformed their peers in the recent past are likely to continue performing well in the near future, while those underperforming may continue that trend.

Choosing to focus on peer comparison emphasizes that cross-sectional momentum is not about the absolute performance of a security in the market or its performance compared to a market index. Rather, it specifically looks at how a security stacks up against similar securities within the same category or sector. This approach helps investors identify trends and potential investment opportunities based on relative strength within a group of comparable investments, which is central to the concept of cross-sectional momentum.
