Performance Measurement and Attribution

Performance Measurement and Attribution organizes investing terms into narrower subsections so readers can separate funds, portfolio construction, investment strategy, index methodology, performance measurement, and sustainable-investing concepts.

Use Return Measurement And Attribution and Risk Adjusted Performance Ratios to move from the broad topic into the specific investing question. The goal is to keep each folder small enough for practical lookup while preserving related concepts together.

This section stays finance-first. Strategy, legal, tax, or product detail is kept here only when it materially affects investment selection, fund economics, portfolio risk, investor returns, or market exposure.
