Know what you can own
Stocks, bonds, ETFs, and funds solve different problems and carry different risks.
After this module
You can explain what an instrument owns, how it produces a return, its main risks, and its costs.
Look through the label
Ticker → Holdings → Risks
Stocks and bonds
A stock is a residual ownership claim; a bond is a contractual lending claim.
- Shareholders participate in business upside but stand behind creditors.
- Bond returns depend on interest, repayment, credit quality, and rates.
- Neither label alone tells you whether the current price is attractive.
Example
A wonderful company can be a poor investment at an extreme price; a high-yield bond may be signaling high default risk.
Funds and ETFs
A fund pools assets. An ETF is a fund structure traded on an exchange; it is not automatically diversified or low risk.
- Read the index, mandate, top holdings, geography, currency, and fee.
- Several funds can overlap and still concentrate the same companies.
- Accumulating and distributing share classes handle income differently.
Example
Two technology ETFs may own nearly the same largest companies despite different names.
Common trap
Owning many tickers is not the same as owning many independent risks.
Passive as a baseline
A broad, low-cost index provides a useful benchmark for the time, risk, fees, and skill required by stock selection.
- Compare every active idea with the simple alternative.
- Include taxes, FX, spreads, and time spent in the comparison.
- A benchmark is a measuring stick, not a promise of future returns.

Look through the ticker
Choose a portfolio label, then inspect the economic exposure underneath. Counting tickers alone can hide concentration.
