Smart Beta Strategies
Smart beta strategies are systematic investment approaches that aim to capture specific market factors or characteristics beyond traditional market capitalization-weighted indexing. These strategies use rule-based methodologies to select and weight securities based on factors such as value, momentum, quality, or low volatility, seeking to enhance returns or reduce risk compared to conventional index investing.
Understanding smart beta strategies
Smart beta represents a hybrid approach between passive and active investment management. While traditional index investing weights securities by market capitalization, smart beta strategies employ alternative weighting schemes based on various factors or characteristics.
These strategies typically share several key features:
- Rules-based methodology
- Systematic implementation
- Transparent factor exposure
- Lower costs compared to active management
- Regular rebalancing schedules
Common smart beta factors
Value
Value strategies target securities trading at lower prices relative to fundamental measures such as:
- Book value
- Earnings
- Cash flow
- Sales
Momentum
Momentum strategies seek to capture the tendency of securities with positive price correlation to continue performing well in the near term. These strategies often involve:
- Measuring historical returns
- Ranking securities by relative strength
- Regular portfolio rebalancing
Quality
Quality-focused approaches emphasize companies with:
- Strong balance sheets
- Stable earnings
- High profitability
- Efficient capital allocation
Low volatility
Low volatility strategies aim to reduce portfolio risk by targeting securities with historically lower volatility levels, often providing better risk-adjusted returns than the broader market.
