Explanation:
Returns-based style analysis (RBSA) uses a multi-factor regression model to regress the portfolio's historical returns against the returns of various style indices (e.g., large-cap, small-cap, value, growth). This approach is specifically designed to decompose a portfolio's returns into its underlying style and factor exposures, allowing the manager to understand the drivers of performance and verify alignment with the stated investment strategy. A holdings-based analysis (HBSA) analyzes the actual constituents at a point in time, but RBSA explicitly decomposes the returns as requested.
