Understanding ETFs and Index Funds
March 30, 2026 · 1 min read
An ETF (Exchange-Traded Fund) is a basket of stocks, bonds, or other assets that trades on a stock exchange like a single share. An index fund is a type of fund that tracks a specific market index.
How They Work
Instead of buying individual stocks one by one, an ETF lets you buy a single fund that holds dozens or hundreds of companies. For example, an S&P 500 ETF holds shares in all 500 companies in that index.
Active vs. Passive
- Passive funds track an index automatically — lower fees, no stock-picking
- Active funds have managers choosing stocks — higher fees, attempting to outperform
Why ETFs Are Popular
- Diversification: One purchase spreads risk across many companies
- Low cost: Passive ETFs typically charge very small management fees
- Accessibility: You can buy a single share of an ETF, making them beginner-friendly
Halal ETFs
Some ETFs are specifically designed with Sharia screening built in, automatically excluding companies that fail compliance criteria. These are sometimes labeled "Islamic" or "Shariah-compliant" ETFs.
