A short glossary
Plain-English definitions of core terms you will meet across the guides. Each is a starting point, not the last word.
- Asset allocation – how you divide your money across broad categories such as stocks, bonds, and cash.
- Bond – a loan you make to a government or company that agrees to pay you interest and return the principal later.
- Brokerage account – an account with a licensed firm that lets you buy and hold investments like stocks and funds.
- Compound interest – the effect of earning returns on both your original money and the returns it has already produced.
- Diversification – spreading money across many investments so that no single one can sink the whole portfolio.
- Dividend – a portion of a company’s profits paid out to shareholders, usually in cash.
- ETF – an exchange-traded fund, a basket of investments that trades on an exchange like a single stock.
- Expense ratio – the yearly fee a fund charges, shown as a percentage of the money you have invested in it.
- Index fund – a fund that aims to match a market index rather than trying to beat it, usually at low cost.
- IRA – an individual retirement account that offers tax advantages for money you set aside for retirement.
- 401(k) – a retirement account offered through an employer, often with contributions taken from your paycheck.
- Portfolio – the full collection of investments you own, viewed together as one whole.
- Volatility – how much and how quickly an investment’s price moves up and down over time.
- Yield – the income an investment pays out, expressed as a percentage of its price.
Trustworthy references
When you want to verify a primary fact, go to the source rather than a secondhand summary. For rules and investor protection, use official regulator websites such as the SEC’s investor education site and FINRA, which also lets you check the background of a broker or firm.
For contribution limits and tax rules, the IRS is the authoritative source. For the details of a specific fund, read that fund’s own prospectus and fact sheet from your fund provider. We keep these references generic on purpose, so you always confirm the current details with the primary source.
