What is an ETF?

ETFsBeginner5 min readUpdated June 2026 · by Amarah Team

ETF stands for Exchange-Traded Fund

An ETF is a basket of many different stocks or bonds bundled into a single investment product. When you buy one share of an ETF, you instantly own small pieces of every company inside that basket.

For example, the Vanguard S&P 500 ETF (VOO) tracks the 500 largest US companies. One share of VOO gives you exposure to Apple, Microsoft, Amazon, Google, Tesla, and 495 other companies — simultaneously.

ETF vs individual stock

Buying one stock means betting on one company. If that company struggles, your investment suffers. Buying an ETF means spreading risk across many companies: even if a few perform poorly, others offset the loss.

ETFs are particularly powerful for new investors because they provide instant diversification without requiring you to research dozens of individual companies.

What do ETFs cost?

ETFs charge an annual expense ratio — a tiny percentage of your investment deducted automatically. VOO's expense ratio is just 0.03% per year. On a 100,000 XAF investment, that's 30 XAF per year.

This makes ETFs far cheaper than actively managed funds, which often charge 1-2% annually and rarely outperform the market anyway.

When ETFs make sense

ETFs are ideal if you want broad market exposure without the complexity of picking individual stocks. They're also perfect for building a long-term "core" position, then adding individual stocks you believe in around that core.

Most professional investors recommend that beginners start with a broad market ETF (like VOO or VTI) before picking individual stocks.
