Broker: The regulated intermediary that holds your account and routes your orders to the market.
BrokerCheck: A free FINRA tool for verifying the registration and disciplinary history of brokers and firms.
Business risk: Risk that comes from how a company operates — competition, debt, customers, regulation — as distinct from swings in its share price.
Buyback: A company purchasing its own shares, which reduces shares outstanding and raises each remaining share's proportional claim. It creates value only if the price paid is sensible.

C

CAGR: Compound annual growth rate — the constant annual rate that would produce a given total change over a period.
Capital: Money used to fund a business or an investment. Companies raise it by issuing shares (equity) or by borrowing (debt).

Capital gain: The profit realised when an investment is sold above its cost basis.
Capital-light: Describes a business that needs relatively little investment in physical assets to grow.

Circulating supply: The tokens currently available to trade, excluding locked, unvested or reserved tokens. Data providers can count it differently.
Competitive position: How well a company holds up against its rivals.
Compounding: Growth earned on previous growth. Under positive-return assumptions it can become the largest part of a balance over long periods.
Concentration risk: Risk created when too much of your outcome depends on one holding, sector or theme.
Confirmation bias: Favoring information that supports what you already believe.
Consensus: The rules by which a blockchain network's computers agree on which transactions are valid and in what order.

Core holding: A broad, long-term position meant to form the base of a portfolio, as distinct from smaller positions around it.
Correction: A decline, conventionally 10% or more from a recent high, smaller than a bear market. The threshold is a convention, not a rule.

Cost basis: Generally what you paid for an investment including purchase costs, adjusted for events such as splits; used to calculate taxable gain or loss. Gifts and inheritances follow different rules.
Cost drag: How much fees and costs reduce returns over time. Because costs are taken from a growing balance, their effect compounds.
Cost of revenue: The direct costs of producing the goods or services a company sold in a period.
Counterparty risk: The risk that the other party to an arrangement — an exchange, lender or issuer — fails to meet its obligations.
Coverage: How much reliable evidence exists for a company. Low coverage means less can be assessed.
Credit risk: The risk that a borrower fails to make promised payments.
Crossover point: In an illustration, the point where total growth first exceeds total contributions. Its timing depends entirely on the assumed return; with low or negative returns it may arrive much later or never.
Current assets: Assets expected to be turned into cash or used up within about a year, such as cash, receivables and inventory.
Custodial: An arrangement where a platform holds the private keys for you, so you depend on that platform's security and solvency.
Custody: Who actually controls an asset. In crypto, whoever holds the private keys can sign transactions, subject to the token's own contract rules.
Customer concentration: Relying on a few customers for a large share of revenue. Companies may disclose it in filings; Pro Investor Academy's research does not currently flag it.

D

Data freshness: How recent data is compared with when you are using it. Research should show the date the data was observed, not just when the page loaded.
Deceleration: A growth rate that is falling from one period to the next. A company can still be growing while decelerating.
Decision journal: A dated record of what you decided, why, and what you expected, used to check your reasoning later.
Depreciation: Spreading the cost of a long-term asset over its useful life as an expense. It lowers reported profit without a cash payment in that period.

Diversification: Spreading money across many investments so no single failure dominates the outcome.
Dividend: Cash a company pays out to shareholders from its profits.
Dividend yield: Annual dividends per share divided by the share price.
Dollar-cost averaging: Investing a fixed amount at regular intervals regardless of price.
Drawdown: The decline from a previous peak, measured peak to trough.
Drift: When a portfolio's mix moves away from its target because some holdings grew faster than others.

Economic driver: The underlying force — such as interest rates, consumer spending or a single large customer — that several investments depend on.
EDGAR: The SEC's free public database of company regulatory filings.
Elite Investor Activity: Part of Ownership Intelligence (half of that component's weight): evidence from quarterly 13F filings by selected large investment managers. It describes dated past filings, not current positions.
Emergency fund: Accessible cash reserved for unexpected expenses, so investments never have to be sold at a bad moment.
Employer match: Money an employer adds to a U.S. workplace retirement plan such as a 401(k) based on what you contribute. Match formulas and vesting schedules are set by each plan.
EPS: Earnings per share. Basic EPS is earnings available to common shareholders divided by weighted-average common shares; diluted EPS also counts potential shares from options and convertibles.
Equity: Ownership. A share of stock is a unit of equity; on a balance sheet, shareholders' equity is assets minus liabilities.
Estate planning: Arranging how your assets will be managed and passed on at death or incapacity, usually with legal documents such as a will. The rules depend on where you live.
ETF: Exchange-traded fund: a basket of investments that trades on an exchange like a single stock.
Ethereum: A programmable blockchain on which applications run as smart contracts.

F

Falsification: The pre-written condition that would tell you your investment reasoning was wrong.

Forced sale: Selling because you need the cash or a lender requires it, rather than by choice — often at a bad moment.
Form 13F: A quarterly SEC report filed by institutional investment managers with at least $100 million in qualifying U.S. securities, due 45 days after quarter end. Managers based outside the U.S. can also have to file. It covers only securities on the SEC's Official List (mainly U.S.-listed stocks, ETFs and closed-end funds, plus certain convertible debt, options and warrants) and leaves out short positions, cash, mutual funds and most non-U.S. holdings.
Fractional share: Part of a single share, allowing investment by dollar amount.
Free cash flow: Cash generated by operations after the capital spending needed to maintain the business.
Free cash flow yield: Free cash flow divided by market capitalization. Because free cash flow is defined differently by different sources, check which definition is used.
Fund closure: When a fund's sponsor shuts a fund and returns cash to shareholders. It ends your intended holding and can create a taxable event in a taxable account.
Fundamental Momentum: One of our four scored components: whether measured business fundamentals are improving or deteriorating.

Holdings: The individual securities a fund or portfolio owns.
Hype cycle: A pattern in which attention to a new idea surges, collapses and then settles.

I

Illusion of control: Believing you can influence outcomes that are largely down to chance.
Immutability: Once confirmed under later blocks, a blockchain record is extremely costly to change. That is not strictly impossible, and it does not make a recorded transaction correct or reversible.
Immutable snapshot: A saved research record that is never edited after it is created, so past results can be checked against exactly what was known at the time.
Index: A measurement of a group of investments, such as the S&P 500. An index cannot itself be bought.
Index fund: A fund designed to match an index rather than beat it, usually at low cost.

Interest-rate risk: The risk that rising interest rates reduce the market value of existing bonds.
International ETF: An ETF holding securities from outside your home country. It adds currency and country risks.
Inverse ETF: A fund designed to move opposite to an index over a single day. It resets daily, so results over longer periods can differ sharply from the index's inverse.
Investment policy: A written set of personal rules covering goals, allocation, contributions and when to review or rebalance.
Investment process: The repeatable steps you use to research, decide, size and review investments.
Investment thesis: A written explanation of why you own something, what evidence supports it and what would show it is wrong.
IPO: Initial public offering — the first sale of a company's shares to the public.
IRA: An individual retirement account in the U.S., available in traditional and Roth forms.

Large cap: A company with a large market capitalization. Cut-offs are conventions set by index providers and change over time; there is no single official threshold.
Leverage: Using borrowed money. It magnifies both gains and losses.
Leveraged ETF: A fund aiming to multiply a daily index move. It resets daily and is not an accumulation vehicle.
Liability: An amount a company owes to others, such as loans, bonds or unpaid bills.

Methodology: The documented rules a research process follows.
Moat: A durable competitive advantage that makes a business hard to displace.

Monitoring: Checking holdings at planned intervals against your thesis and your rules.
Mutual fund: A pooled fund that transacts once per day at its net asset value.

N

Net asset value: A fund's assets minus its liabilities. Divided by shares outstanding, it gives NAV per share.

O

Open-market purchase: An insider buying shares on the market with their own money, reported on Form 4 with transaction code P.
Operating cash flow: Cash generated or used by a company's normal business activities in a period, shown on the cash flow statement.

Operating margin: Operating profit as a percentage of revenue — a measure of operational efficiency.
Overconfidence: Overestimating your knowledge or your ability to predict outcomes.
Overfitting: Tuning a model so closely to past data that it captures noise rather than a lasting pattern, so it looks better in a backtest than it will in practice.
Overlap: When two funds own many of the same securities, so holding both adds less diversification than it appears to.
Ownership concentration: How much of a company's shares are held by a small number of owners.
Ownership Intelligence: One of our four scored components: measured evidence about who owns a company, from public disclosures.

P

P/E ratio: Share price divided by earnings per share — how much is paid per dollar of current earnings.

Point-in-time: Using only the information that was genuinely available on a given historical date.
Ponzi scheme: A fraud that pays existing investors with new investors' money rather than real profits.
Position sizing: Deciding how much to hold in one investment. It limits how much a mistake can cost; it does not make the choice unimportant.
Primary source: The original document or data, such as a company's own filing, rather than someone's summary of it.
Private key: The secret that authorises crypto transactions. Control of the key is control of the asset.
Pro Investor Score: Our composite stock research score: Risk Intelligence 30%, Long-Term Potential 30%, Fundamental Momentum 20%, Ownership Intelligence 20%. Risk Intelligence and Long-Term Potential are tied as the largest components. Covers U.S. stocks only, not ETFs or crypto.

Pyramid scheme: A structure that pays participants for recruiting others rather than for any real product or return.

R

Real return: A return after subtracting inflation — a measure of how much more the money can actually buy.

Rebalancing band: A tolerance range around a target allocation. You rebalance only when a holding drifts outside it.
Recency bias: Assuming the recent past will continue.
Recovery: A return to a previous peak after a decline. Past recoveries have taken months to many years, and some investments never recover.

Regulatory filing: A document a company, fund or investor must submit to a regulator such as the SEC.
Reinvestment: Putting profits or dividends back into a business or investment instead of paying them out.

Resilience: A business's ability to keep operating and earning through downturns, competition or shocks.
Return on equity: Net income divided by shareholders' equity. Borrowing can raise it, so read it alongside the company's debt.
Return on invested capital: Conventionally after-tax operating profit divided by a stated measure of invested capital (for example debt plus equity, less excess cash). Definitions vary; check which is used.
Revenue: Total sales before any costs are subtracted.
Review trigger: A pre-set condition that prompts you to re-examine a holding. A review is not an automatic sale.
Risk Intelligence: One of our four scored components: measured evidence about a company's risk characteristics.

S&P 500: An index of 500 large U.S. companies weighted by market capitalization.
Scheduled review: A review done on a fixed calendar rather than in reaction to price moves.
Screener: A tool that filters a list of investments by chosen criteria. A match is a starting point for research, not a conclusion.
Sector: A grouping of companies in similar businesses, which often move together.
Sector ETF: An ETF holding companies from one industry sector. It is more concentrated than a broad-market fund.
Self-custody: Holding your own crypto private keys rather than relying on a platform. It controls signing, but issuer-controlled tokens can still be frozen by their issuer.
Sell discipline: Written reasons for selling, decided in advance, before emotions are involved.
Sentiment: The overall mood of investors toward a market or security. It can move prices in the short term regardless of business results.
Sentiment cycle: The swing of investor emotion from optimism to fear and back, which often moves alongside market cycles.

Share: A unit of ownership in a company.
Share class: Different categories of a company's shares, which can carry different voting rights.
Shareholder: Someone who owns at least one share of a company.
Shares outstanding: The total number of a company's shares currently held by all owners.
Signal: A measured indicator that something has changed and may deserve attention. It is not a prediction or an instruction.
Small cap: A company with a relatively small market capitalization. As with large cap, the cut-off is a convention, not an official rule.
Smart contract: Code on a blockchain that executes automatically when its conditions are met.
SPIVA: S&P Dow Jones Indices' scorecards comparing active fund performance against benchmarks.
Stablecoin: A crypto token designed to hold a steady value, usually against a currency such as the U.S. dollar.
Staking: Locking tokens to help secure a proof-of-stake network in return for rewards. Risks include lock-up periods, penalties and the platform you stake through.
Standard deviation: A statistical measure of how widely values, such as returns, spread around their average. A common measure of volatility.
Stock grant: Shares awarded as pay rather than bought. A grant says little about the insider's own view of the stock.
Stock split: Dividing existing shares into more shares at a proportionally lower price. Economically neutral.
Suggested Investment Score: The earlier name of the Pro Investor Score™. Same model and weights; the score is now shown under the Pro Investor Score name.

T

Target allocation: The intended mix of investments, for example 80% stocks and 20% bonds.

Taxable account: A standard brokerage account with no special tax treatment.
Taxable event: An action that can create a tax bill, such as selling at a gain or receiving a dividend in a taxable account. These examples follow U.S. rules; other countries differ.
Thematic fund: A fund built around a theme such as a technology trend, often concentrated in a narrow group of related companies.
Ticker: The short code identifying a listed security.
Time horizon: How long until you need the money. It determines what you can responsibly own.
Token burn: Permanently removing tokens from supply by sending them to an address no one can spend from. A burn on its own does not create value.
Tokenomics: The rules for a crypto token's supply and distribution: how many exist, who received them, when new ones are released or destroyed, and what the token is used for.
Total return: Price change plus income such as dividends or interest, usually assuming the income is reinvested. Check whether a quoted figure is before or after fees.
Tracking difference: The gap between a fund's return and its index's return over a period, usually driven by fees and costs.
Tracking error: How much a fund's return varies around its index's return over time, usually measured as the standard deviation of the differences.
Trading plan: A pre-arranged plan (in the U.S., under SEC Rule 10b5-1) that lets insiders schedule future trades in advance.
Turnover: How frequently holdings are bought and sold. Higher turnover means higher costs.

U

Universe: The full set of investments a screen, index or model considers.
Unusual attention: A spike in discussion, searches or trading compared with a security's normal level. Attention is not evidence of value.

V

Valuation: Assessing the price of an investment relative to the business behind it.
Vesting: A schedule that releases tokens or shares to their holders gradually. When large amounts unlock, the supply available to sell can rise.
Volatility: How sharply a value moves over time. High volatility means a wider range of short-term outcomes.

W

Watchlist: A list of investments you are following, not necessarily owning.
Weighting: How much each holding counts in an index or portfolio — for example by market capitalization, or equally.
Withdrawal phase: The years in which you are mainly taking money out of investments to spend.
Working capital: Current assets minus current liabilities. Changes in it are one reason cash flow can differ from profit.
