Published / Last Updated on 26/03/2026
Clear Definitions, Pros & Cons, and Core–Satellite Use
What Are Passive Funds?
Passive funds track a market index or sector without active stock‑picking.
Examples
- FTSE 100
- FTSE All‑Share
- S&P 500
- Sector ETFs (bonds, gilts, clean energy, healthcare, technology)
Key Features
- Low fees: typically 0.1%–0.3% per year
- Broad diversification
- Income options:
- Distribution units (pay dividends)
- Accumulation units (reinvest dividends)
- Some ultra‑low‑cost trackers retain dividends to offset expenses
Pros
- Very low cost
- Transparent and rules‑based
- Hard for many active managers to outperform consistently
- Ideal for long‑term, broad‑market exposure
Cons
- No ability to avoid weak sectors
- No tactical decisions during volatility
- Will match the index — never beat it
What Are Active Funds?
Active funds use managers and analysts to select investments with the goal of outperforming a benchmark.
Key Features
- Higher fees: typically 0.4%–1.0%+ per year
- Human decision‑making
- Ability to adjust holdings during market volatility
Pros
- Potential to outperform the market
- Useful in specialist or inefficient markets
- Tactical flexibility
- Suitable when you want a manager to handle asset allocation
Cons
- Higher charges reduce net returns
- Many managers fail to beat passive benchmarks
- Performance varies widely between managers
Industry Insight
As Ashley Robert‑Clark once discussed with a huge investment company board director:
If an active manager cannot outperform a passive index, why pay for their salary and bonuses?
This remains a core argument in the debate.
Active vs Passive: When to Choose Each
Choose Passive When You Want
- Low charges
- Broad, diversified exposure
- Sector‑average performance at minimal cost
- A simple, transparent approach
Choose Active When You Want
- Specialist or niche sector exposure
- A chance to outperform the market

Core–Satellite Strategy
A widely used approach combining both fund types.
Core (Passive)
- Low‑cost ETFs and trackers
- Broad, stable, long‑term exposure
- Keeps overall fees low
- Reduces risk through diversification
Satellite (Active)
- Higher‑conviction active funds
- Focus on sectors with strong growth potential
- Useful when you lack expertise in niche areas
- Adds selective risk without inflating total costs
FAQs: Active vs Passive Funds
What is the main difference between active and passive funds?
Passive funds track an index; active funds try to beat it through stock selection and tactical decisions.
Are passive funds always cheaper?
Yes. Passive funds typically cost 0.1%–0.3% per year, while active funds often cost 0.4%–1.0%+.
Do active funds perform better?
Some do, especially in specialist sectors or inefficient markets, but many fail to outperform their passive benchmarks consistently.
Which is better for beginners?
Passive funds are usually more suitable due to low cost, simplicity, and broad diversification.
Can I combine active and passive funds?
Yes. A core–satellite strategy uses passive funds for the core and active funds for targeted opportunities.
Do passive funds pay dividends?
Some do (distribution units). Others reinvest dividends (accumulation units). A few retain dividends to offset expenses.
When should I use active funds?
When you want specialist exposure, tactical management, or a chance to outperform the market.
