One company versus a basket
Buying one stock exposes you directly to one company's business performance and valuation. An exchange-traded fund may hold dozens or thousands of assets under a defined investment strategy.
Not every ETF is diversified
A fund concentrated in a single sector, theme or leveraged strategy can behave differently from a broad-market index ETF. Read the prospectus, top holdings, objective and expenses.
Compare fees and risks
Expense ratios reduce fund returns over time. Also consider tracking error, trading spreads, fund liquidity and the risks associated with underlying assets.
Research exercise
Pick two hypothetical fund strategies and compare concentration, fees and top holdings. Explain why owning multiple overlapping funds might not add much diversification.
Put it into practice
Explain the main idea in your own words, identify two risks and find a primary source to validate an important claim. Document what you still don't know.
