Rules-based ETFs, also known as smart beta ETFs, use predetermined rules or algorithms to select and weight securities in their portfolios. These ETFs aim to outperform traditional market-capitalization-weighted ETFs by targeting specific factors such as value, momentum, quality, or volatility.

Characteristics of Smart Beta ETFs:

Strategic Factor Weighting: Securities are weighted based on fundamental or quantitative factors, not just market capitalization.

Higher Returns Potential: These ETFs are designed to capture excess returns (alpha) relative to a benchmark.

Lower Costs: Smart beta strategies often combine active and passive management elements at a lower cost than traditional active funds.

Explanation of Options:

A . Rules-based: Correct answer. Smart beta ETFs are built on rule-based frameworks designed to achieve specific investment objectives.

B . Standard: Refers to traditional, market-cap-weighted ETFs, not smart beta.

C . Synthetic: Refers to ETFs that use derivatives to replicate returns of an underlying index, unrelated to smart beta.

D . Index-based: Includes standard ETFs tracking an index but does not apply specifically to smart beta.
