Stocks, funds, ETFs — three terms beginners often confuse. The difference is simple: A stock is a piece, a fund is a basket, an ETF is a cheap basket.

Stocks: You Buy a Piece of a Company

When you buy an Apple stock, you own a tiny share of Apple. You profit when Apple grows (price increase) and when Apple distributes profits (dividend). The risk: If Apple does poorly, you lose money.

Funds: A Manager Chooses for You

An investment fund collects money from many investors and invests in dozens or hundreds of stocks. A fund manager decides which stocks to buy. The advantage: Diversification. The disadvantage: High costs (1-2% per year).

ETFs: Like a Fund, But Cheaper and More Transparent

An ETF is a fund traded on the stock exchange. The crucial difference: No manager makes decisions. The ETF simply tracks an index. Advantages over classic funds:

90% cheaper: 0.1-0.3% TER instead of 1-2%
More transparent: You know exactly which stocks are included
More liquid: Tradeable anytime on the exchange
Historically better: 85-90% of fund managers fail to beat their index long-term

Comparison

Stock: 1 company | High risk | 0 ongoing costs | Full price and dividend risk
Fund: 50-200 stocks | Medium risk | 1-2% p.a. | Manager decides
ETF: 500-3,000 stocks | Low risk | 0.1-0.3% p.a. | Index decides automatically

What Suits Whom?

Beginners: ETF savings plan — cheap, diversified, no knowledge needed
Advanced: ETF as core + individual stocks as satellite
Classic funds: Almost never recommended — too expensive for the delivered performance

Bottom Line: For 90% of retail investors, ETFs are the best choice. They offer maximum diversification at minimum cost.
