Investing Terms
Investing has more jargon than almost any corner of personal finance: asset classes, fund structures, account types, market measures, and the acronyms layered on top of all of it. These terms cover the vocabulary you meet when you put money to work in markets: what things are, how they behave, and what they cost.
The stakes of understanding it are practical, not academic. Most expensive investing mistakes start as vocabulary problems: confusing a fund with the account that holds it, or a return figure with the return you actually keep. Each definition below is written in plain English with a worked example, so the words stop being a barrier to good decisions.

Essential investing terms
- Asset Allocation
Asset allocation is how you divide a portfolio among asset classes (mainly stocks, bonds, and cash), and it is the decision that most shapes how much your portfolio grows and how violently it swings along the way.
- Assets Under Management (AUM)
Assets under management (AUM) is the total market value of investments a firm manages on behalf of clients. In financial advice, "the AUM model" refers to charging clients an annual fee calculated as a percentage of the assets the advisor manages, commonly around 1%.
- Bitcoin
Bitcoin is the first and largest cryptocurrency, launched in 2009 and running on its own public blockchain with no issuer, no company behind it and a supply schedule written into its software. It is the asset the rest of the crypto market is priced and compared against.
- Bond
A bond is a debt security: a loan you make to a government or a company, which promises to pay you interest for a set period and to return the principal at maturity. Being a lender rather than an owner is what caps the upside and what puts you ahead of stockholders if the issuer fails.
- Brokerage Account
A brokerage account is an account at a broker-dealer used to buy, hold and sell securities. This page covers the ordinary taxable version, the one with no contribution limit, no withdrawal rules and no special tax treatment, and what is and is not protected inside it.
- Capital Gains Tax
Capital gains tax is the tax on profit from selling an asset for more than you paid. Assets held over one year get preferential long-term rates of 0%, 15%, or 20%; assets held a year or less are taxed as ordinary income.
- Consumer Price Index (CPI)
The Consumer Price Index is the Bureau of Labor Statistics measure of how prices paid by urban consumers change over time. There is no single "the CPI", because BLS publishes several versions of it, and three different ones govern federal tax brackets, the Social Security increase, and Series I savings bond rates.
- Cost Basis
Cost basis is what you are treated as having paid for an asset, and it is the figure subtracted from a sale price to produce a taxable gain or loss. The number that actually does that job is the adjusted basis, because basis changes over time.
- Crypto Taxes
Crypto taxes are the federal income tax rules that apply to digital assets. Because the IRS treats them as property rather than currency, every disposal is a taxable event, basis must be tracked wallet by wallet, and broker reporting is phasing in on two different dates.
- Cryptocurrency
A cryptocurrency is a digital asset recorded on a cryptographically secured distributed ledger and issued by no government or bank. Despite the name, federal tax law treats it as property rather than currency, and it sits outside both deposit insurance and most brokerage customer protection.
- Custodian
A custodian is the institution that holds your assets, keeps the records, settles the transactions, and sends you the statements. It does not choose the investments and does not guarantee their value, and inside a retirement account the tax code treats it as a trustee.
- Diversification
Diversification is spreading your investments across many securities and asset classes so that no single company, industry, or country can sink your portfolio: it removes single-holding risk, though not market risk.

- Dividend Yield
Dividend yield is the annual dividend per share divided by the share price, expressed as a percentage. Because the price sits in the denominator, a yield can rise for the encouraging reason that the payment went up or the discouraging reason that the price went down, and the figure alone does not say which.
- Dollar-Cost Averaging (DCA)
Dollar-cost averaging (DCA) is investing a fixed dollar amount on a regular schedule regardless of market conditions, so you automatically buy more shares when prices are low and fewer when they are high.

- Farmland Investing Coming soon
Farmland investing is putting money into agricultural land to earn income from farming and potential appreciation of the land itself.

- Fixed Income Coming soon
Fixed income is the investment category of bonds and similar securities that pay set interest on a schedule, generally offering steadier returns and lower risk than stocks.
- Flash Crash Coming soon
A flash crash is a sudden, severe drop in securities prices that reverses within minutes or hours, often driven by automated trading rather than fundamental news.
- Floating Rate Note Coming soon
A floating rate note is a bond whose interest rate adjusts periodically with a benchmark rate, so its payments rise and fall with market interest rates.

- Gold Investing
Gold investing means holding gold for its price rather than for any income it produces, through bullion and coins, an exchange-traded product, futures, or the shares of mining companies. The routes differ sharply in cost, custody and tax, and gain on the metal carries its own higher capital-gains ceiling.
- Gold Standard Coming soon
The gold standard was a former monetary system in which a country's currency was directly backed by and convertible to a fixed amount of gold.
- Good Till Canceled Order Coming soon
A good-till-canceled order is an instruction to buy or sell a security that stays active until it is filled or the investor cancels it, rather than expiring at day's end.

- Growth Stock
A growth stock is a share in a company whose revenue and earnings are expanding, or are expected to, and which typically returns value to shareholders through a rising share price rather than through dividends.

- Guaranteed Return Red Flag Coming soon
A guaranteed-return red flag is a warning sign of fraud in which someone promises high investment returns with little or no risk — a combination that legitimate investments cannot honestly deliver.
- Guidance Coming soon

Infinite banking is a strategy of borrowing against the cash value of a whole life insurance policy to act as your own source of financing.

- Large-Cap Stock
A large-cap stock is a share in one of the largest companies in the market by market capitalization.

- Layer 2 Coming soon
A layer 2 is a secondary network built on top of a main blockchain to process transactions faster and more cheaply before settling them on the underlying chain.
- Lazy Portfolio Coming soon
A lazy portfolio is a simple, low-maintenance mix of a few broad index funds designed to be held for decades with little more than occasional rebalancing.

Leverage is the use of borrowed money to increase the size of an investment, magnifying gains when prices move your way and magnifying losses when they don't.
- Leveraged ETF Coming soon
A leveraged ETF is a fund engineered to deliver a multiple of an index's daily return, and because it resets each day its long-term results can drift far from the index — making it a short-term trading tool, not a buy-and-hold investment.
- Life Insurance as an Investment Coming soon
Life insurance as an investment means using permanent policies that build cash value as a savings vehicle, an approach that carries high costs and complexity.
- Limit Order Coming soon
A limit order is an instruction to buy or sell a security only at a specified price or better, guaranteeing the price you will accept but not that the trade will happen.

Lump-sum investing is putting a large amount of cash into the market all at once, rather than spreading the purchases out over time as with dollar-cost averaging.

- Margin Call Coming soon
A margin call is a brokerage's demand that you add money or securities to your account because its value has fallen too far relative to what you borrowed, and your holdings can be sold without your consent if you don't.
- Market Capitalization
Market capitalization is the share price multiplied by the number of shares outstanding, and it is the standard measure of a company's size in the stock market.

A market maker is a firm that continuously offers to buy and sell a security, providing liquidity and profiting from the gap between its buy and sell prices.

- Market Timing Coming soon
Market timing is the attempt to boost returns by predicting when markets will rise or fall and buying or selling ahead of those moves — something decades of evidence show even professionals rarely do successfully.

- Money Market Fund
A money market fund is a mutual fund that invests in short-term debt. It is a security, not a bank deposit, so it is not FDIC-insured and you can lose money in it.

- Money Supply Coming soon
The money supply is the total amount of cash and easily spendable money circulating in an economy.
- Money-Weighted Return Coming soon
Money-weighted return measures the return actually earned on your dollars, factoring in the size and timing of your deposits and withdrawals — so it reflects your personal experience rather than the strategy alone.

The over-the-counter market is a network where securities trade directly between parties rather than on a formal exchange, often involving smaller or less-regulated companies.

- Passive Investing
Passive investing is an approach in which the investor declines to bet on which securities will do well or on when to be in the market, and instead holds broad, rules-based holdings and keeps holding them.

A spot bitcoin ETP is an exchange-traded product that holds bitcoin itself and trades on a stock exchange like a share.
