Active ETFs combine professional management with the liquidity and transparency of ETFs, making them powerful tools for portfolio construction. They offer investors access to active security selection and the potential to outperform benchmarks, while still benefiting from intraday trading, tax efficiency, and often lower costs. 

These funds are especially valuable in areas of the market with inefficiencies, where deep research and targeted exposure can improve outcomes. Derivative-income ETFs can enhance portfolio income and stability by generating yield through options, offering an equity-based alternative to fixed income. 

Meanwhile, buffer ETFs help manage downside risk by capping losses (and gains) over set periods, making them useful for preserving capital during volatile markets. 

Finsum: Together, these active ETF strategies provide investors with flexible, diversified, and goal-oriented components for building resilient and adaptive portfolios.
