📊 Excess Return (Alpha) Measurement Formula
Alpha (α) = total fund return - [risk-free rate + beta × (market return - risk-free rate)]
▶ Alpha > 0: Active fund manager achieves outperformance compared to the market average
⚖️ Key Comparison at a Glance
| Category | Passive ETF | Active ETF (Active) |
|---|---|---|
| Operational Goals | Index tracking (market average return) | Index Outperformance (Alpha Return) |
| Management Fee | Very low (0.03% to 0.1%) | Relatively high (0.5% to 0.85%) |
| Change Portfolio | Adjusted only when the index changes regularly | Adjustments are made every day at the discretion of the manager. |
