What Is a Like Book?
A like book is a record that lists securities, accounts, or investments grouped by similarity. It helps analysts compare assets with shared characteristics such as sector, risk profile, or strategy.
How a Like Book Works
Portfolios are organized into clusters based on factors like industry, market capitalization, or credit quality. Analysts use the like book to monitor concentration, identify overlaps, and evaluate risk across similar positions.
Why a Like Book Matters
By grouping similar holdings, a like book supports clearer performance comparisons and better allocation decisions. It is commonly used in asset management, trading desks, and research to streamline analysis.
