ETF Foundations · ETFs
An ETF gives you an interest in a portfolio, not direct ownership of every security inside it. Learn what the wrapper does and which risks remain.
Start with the portfolio
An exchange traded fund pools investors' money into a portfolio under a stated mandate. A share represents a proportional interest in that fund. The portfolio might contain hundreds of companies, a selected bond market or a concentrated strategy. The word ETF describes a structure and trading format. It does not tell you whether the investment is diversified or appropriate for a particular goal.
Separate the fund from its manager
The investment manager makes decisions within the mandate. Custody, administration and other arrangements are described in the prospectus. Buying shares in a fund managed by a large financial company does not mean buying that company's ordinary shares. Nor does the manager's reputation guarantee your capital. Follow the legal ownership chain before relying on a familiar name.
A simple ownership calculation
Imagine a fund with net assets of $20 million and one million shares outstanding. Its net asset value is $20 per share. Holding 100 shares gives a $2,000 interest at that NAV, or 0.01% of the fund. If a company is 8% of the portfolio, your indirect exposure is approximately $160. That calculation describes exposure. It does not give you a separately tradable parcel of that company's shares.
Write down what can go wrong
Inspect holdings, concentration, borrowing and derivatives before comparing recent returns. A portfolio of risky assets remains risky inside a fund. A sector ETF can fall sharply even with many holdings if their businesses respond to the same shock. Record the investment mandate in one sentence and list the main sources of loss. If you cannot do that, continue researching before considering a trade.
Try it yourself
A $6,000 fund position has 12% in one issuer. What is the approximate indirect issuer exposure, and can you sell that issuer alone from your ETF holding?
Show the worked answer
The exposure is $720. You normally sell ETF shares rather than individual portfolio holdings. To change the issuer exposure independently you would need a different portfolio decision.
