Active fund
What is Active fund?
An active fund gives an investment manager discretion to select, size, and trade positions in pursuit of a stated objective rather than mechanically replicating a benchmark. Active management can seek absolute return, income, risk control, or benchmark outperformance, and its success must be assessed after all costs, taxes, and unintended exposures over appropriate periods.
How active management works
The manager operates within prospectus, mandate, regulatory, liquidity, and risk limits. Decisions may involve security selection, sector and country allocation, duration, currency, derivatives, cash, and timing. Some active funds remain close to a benchmark, while unconstrained strategies can differ substantially. The benchmark still matters for measuring opportunity set, risk, fees, and value added.
Sources of relative return
Gross excess return can come from research, portfolio construction, trading, stewardship, or access. Net alpha must survive management fees, transaction costs, taxes, capacity, and unintended factor exposures. A manager can outperform because value, size, momentum, credit, duration, or currency happened to perform well, so attribution should distinguish systematic tilts from security-specific contribution and repeatable process.
Example
A global equity fund beats its benchmark by 2% annually before fees but charges 1.2% and incurs 0.5% additional trading cost. Only 0.3% remains before tax. If its performance came mainly from a persistent small-cap tilt, an investor should compare that net result with a lower-cost portfolio delivering similar factor exposure rather than crediting all outperformance to selection.
How to evaluate one
Assess philosophy, people, process, portfolio, performance, price, and parent organization. Review holdings, active share, tracking error, turnover, capacity, drawdowns, attribution, team changes, and risk controls. Use rolling and full-cycle periods, appropriate benchmarks, and peer comparisons without selecting only favorable dates. Qualitative evidence matters because a short return history cannot reliably separate skill from luck.
Risks and practical checklist
Active funds face manager, key-person, style-drift, concentration, liquidity, operational, and benchmark-relative risk in addition to underlying markets. Past outperformance can attract assets that dilute future opportunity. Verify share class and total cost, monitor process consistency, and define sell criteria before investing. Do not chase recent rankings, and do not reject a sound process solely because its intended style temporarily underperforms.
