The investing glossary,
in plain language.

10-K▾

The comprehensive annual report that every publicly traded U.S. company must file with the SEC. A 10-K contains audited financial statements, a full description of the business, risk factors, and management discussion and analysis.

Real-life exampleApple 10-K runs over 80 pages and discloses everything from iPhone unit sales trends to specific geopolitical risks the company faces in China. Investors who read it have an informational advantage over those who rely on news summaries.

52-Week Range▾

The highest and lowest prices a stock has traded at over the past 52 weeks. It gives investors a quick sense of where the current price sits relative to recent history, but it says nothing about whether the business is fundamentally cheap or expensive.

Real-life exampleA stock with a 52-week range of $80 to $160 trading at $84 looks cheap on paper. But if the business is losing market share rapidly, the low price may be fully justified.

Annual Percentage YieldAPY▾

The real return you earn on savings or an investment over one year, including the effect of compounding. Compounding means you earn returns on your returns, not just on your original amount.

Real-life exampleYour savings account says it pays 0.5% APY. Inflation is running at 3%. In real terms, your money is losing about 2.5% of its buying power every year, even though your balance is technically going up.

Asset▾

Something you own that is expected to generate value or income over time, or that you can sell for money. In investing, the most important distinction is between productive assets, which generate ongoing income, and non-productive assets, which just sit there.

Real-life exampleA rental apartment is an asset. It produces rent every month. A vintage sneaker collection might increase in value, but it produces nothing while it sits in a box.

Balance Sheet▾

A financial statement showing a company total assets, total liabilities, and shareholders equity at a specific point in time. The fundamental accounting equation: Assets = Liabilities + Equity.

Real-life exampleApple 2023 balance sheet showed $352 billion in assets, $290 billion in liabilities, and $62 billion in shareholders equity. The balance sheet is a snapshot of financial health at a single moment.

Barter▾

Trading goods or services directly for other goods or services, without using money. The problem with barter is that it requires both people to have exactly what the other wants at exactly the same time.

Real-life exampleYou have fish and want bread. The baker has bread but wants shoes, not fish. Barter fails. This is the exact problem money was invented to solve.

Book Value▾

The net worth of a company as recorded on its balance sheet: total assets minus total liabilities. Also called shareholders equity. It represents what owners would theoretically receive if the company liquidated all assets and paid all debts.

Real-life exampleA company with $500M in assets and $200M in liabilities has a book value of $300M. If it trades at a market cap of $180M, its price-to-book ratio is 0.6x.

Capital▾

Wealth in the form of money or other assets owned by a person or organization, used specifically for starting a company or investing.

Real-life exampleThe 50,000 liras needed to buy the new steam-powered fishing boat is the capital required to expand the business.

Capital ExpenditureCapEx▾

Cash spent by a company to acquire, maintain, or upgrade physical assets such as property, equipment, buildings, or technology infrastructure. CapEx is subtracted from operating cash flow to calculate free cash flow.

Real-life exampleTesla spending $8 billion building new Gigafactories is capital expenditure. It reduces current free cash flow but is intended to generate significantly more cash flow in the future.

Cash Flow Statement▾

A financial statement tracking the actual movement of cash into and out of a business, divided into three sections: operating, investing, and financing activities. It reveals whether reported profits are backed by real cash.

Real-life exampleA restaurant can report $200,000 in net income while having only $22,000 in its bank account. The cash flow statement explains how that gap exists.

Competitive Moateconomic moat▾

A durable structural advantage that allows a business to defend its profits against competition over a long period. Warren Buffett coined the term. A wide moat means competitors cannot easily replicate the business model.

Real-life exampleVisa network connects billions of cardholders with millions of merchants worldwide. A new competitor would need to sign up both sides simultaneously, a nearly impossible task that makes the network effect moat extremely wide.

Consumer Price IndexCPI▾

A measurement of how much a standard basket of everyday goods and services costs. When that basket gets more expensive over time, that rise in cost is what we call inflation.

Real-life exampleIf the CPI basket cost $100 last year and costs $103 this year, inflation is 3%. Your salary needs to have risen by at least 3% just to keep you in the same financial position.

Cost of Goods SoldCOGS▾

The direct costs attributable to producing the goods or services a company sells. Includes raw materials, direct labor, and manufacturing overhead. COGS is subtracted from revenue to calculate gross profit.

Real-life exampleA bakery COGS includes flour, eggs, butter, and the baker wages. Administrative salaries, marketing costs, and rent are not COGS, they are operating expenses.

Creditors▾

People, banks, or businesses to whom money is owed because they previously provided a loan, goods, or services on credit.

Real-life exampleIf a bank lends your business money to buy a boat, that bank becomes a creditor of your company.

Discount Rate▾

In a DCF model, the annual rate of return an investor requires to justify an investment, reflecting both the risk-free rate and the additional risk premium for the specific business. A higher discount rate reduces the present value of future cash flows.

Real-life exampleIf you require a 10% annual return and expect to receive $110 in one year, that payment is worth exactly $100 today ($110 divided by 1.10). The discount rate converts future dollars into today equivalent.

Discounted Cash FlowDCF▾

A valuation method that estimates the intrinsic value of a business by projecting its future free cash flows and discounting them back to their present value. The total of all discounted cash flows equals the estimated intrinsic value.

Real-life exampleIf a business will generate $10M in free cash flow next year and you require a 10% return, that future $10M is worth $9.09M today ($10M divided by 1.10). A DCF sums these calculations across all future years plus a terminal value.

Dividend▾

A portion of a company profits paid directly to shareholders, typically quarterly. Not all companies pay dividends, growth companies often reinvest all profits back into the business instead.

Real-life exampleIf you own 100 shares of a company that pays a $2 annual dividend per share, you receive $200 per year in cash simply for holding the stock.

Earnings Per ShareEPS▾

A company total net income divided by the number of shares outstanding. EPS tells you how much profit each single share of stock represents and is the denominator in the P/E ratio.

Real-life exampleA company with $50 million in net income and 10 million shares outstanding has EPS of $5. If the stock trades at $75, its P/E ratio is 15x.

EBITDAEarnings Before Interest, Taxes, Depreciation, and Amortization▾

A measure of core operational profitability that strips out financing decisions, tax rates, and non-cash accounting charges. Used to compare operating performance across companies with different capital structures.

Real-life exampleTwo companies with identical operations might show very different net income if one is heavily debt-financed. EBITDA removes financing differences to reveal comparable operating performance.

Enterprise ValueEV▾

The total cost to acquire a business outright: market capitalization plus net debt (total debt minus cash). Enterprise value is used in the EV/EBITDA valuation multiple.

Real-life exampleA company with a $500M market cap, $100M in debt, and $40M in cash has an Enterprise Value of $560M ($500M + $100M - $40M). This is what an acquirer would actually pay.

Equityshareholders equity▾

The ownership interest shareholders have in a company, equal to total assets minus total liabilities. Also called book value or net worth. Equity grows when a company generates profits and shrinks when it reports losses or pays dividends.

Real-life exampleIf you own 1,000 shares of a company with 1 million total shares and total equity of $50 million, your proportional ownership stake has a book value of $50,000.

Fiat Currencyfiat▾

Money that has value because a government declares it to be legal tender and because people collectively agree to accept it. Fiat money is not backed by any physical commodity like gold or silver.

Real-life exampleThe U.S. dollar, the euro, and the British pound are all fiat currency. None of them can be exchanged for gold at a government bank anymore.

Free Cash FlowFCF▾

The cash a business generates after paying for all operating costs and capital expenditures required to maintain and grow its asset base. FCF = Operating Cash Flow minus Capital Expenditures. Warren Buffett considers it the most important single number when evaluating a business.

Real-life exampleA company with $80M in operating cash flow and $30M in capital expenditures has $50M in free cash flow, money that can be returned to shareholders, used for acquisitions, or reinvested for growth.

Gold Standard▾

A monetary system where a currency's value is directly tied to a fixed amount of gold. The U.S. ended this system in 1971 when President Nixon cut the link between the dollar and gold.

Real-life exampleBefore 1971, $35 could be exchanged for one ounce of gold at the U.S. government. After Nixon ended the gold standard, the dollar's value was no longer tied to anything physical.

Gross Profit▾

Revenue minus Cost of Goods Sold. Gross profit shows how efficiently a company produces what it sells, before accounting for overhead costs like salaries, rent, and marketing.

Real-life exampleA software company with $100M in revenue and $20M in COGS has $80M in gross profit and an 80% gross margin, typical for software. A grocery chain with the same revenue might have only a 25% gross margin.

Hyperinflation▾

Extremely rapid and out-of-control inflation, where prices rise so fast that the currency becomes nearly worthless. Hyperinflation usually happens when a government prints enormous amounts of money without any corresponding increase in real goods or services.

Real-life exampleIn Zimbabwe in 2008, inflation reached 89.7 sextillion percent per month. A $100 trillion Zimbabwean dollar note could barely buy a loaf of bread.

Income Statementprofit and loss statement▾

A financial statement showing a company revenues, costs, and profits over a specific period. It starts with revenue at the top, subtracts each layer of costs, and arrives at net income at the bottom.

Real-life exampleThe income statement answers one question: did the business make money this period? Revenue minus COGS equals Gross Profit. Gross Profit minus Operating Expenses equals Net Income.

Inflation▾

The gradual increase in prices over time, which means your money loses purchasing power and buys fewer things than it used to.

Real-life exampleIf an ice cream cone costs $2 today but $4 next year, inflation has cut the buying power of your cash in half.

Intangible Asset▾

An asset with no physical form that generates economic value, such as patents, trademarks, brand loyalty, software, copyrights, and proprietary data. Intangible assets often cannot be fully captured on a balance sheet at their true market value.

Real-life exampleCoca-Cola brand is an intangible asset worth an estimated $35 billion. It does not appear on the balance sheet anywhere near that value, yet it is precisely why the company can charge premium prices for what is essentially sugar water.

Interest Rate▾

The cost of borrowing money, or the reward for saving it, expressed as a percentage per year.

Real-life exampleYou take out a $10,000 car loan at 6% interest per year. After one year, you owe $10,600. The extra $600 is the cost of borrowing.

Intrinsic Value▾

The actual underlying economic worth of a business, independent of its current market price. Calculated by estimating all future cash flows the business will generate and discounting them to present value. Intrinsic value is always an estimated range, not a precise number.

Real-life exampleIn 1973, Warren Buffett estimated the Washington Post intrinsic value at $400 million while the market priced it at $80 million. He bought aggressively and earned 3,000% over the following decade as price converged to value.

Legal Tender▾

Money that the government has declared must be accepted as payment for any debt. If something is legal tender, no one can legally refuse it as payment within that country.

Real-life exampleU.S. dollar bills are legal tender in the United States. A shop cannot legally refuse to accept them as payment.

Leveragefinancial leverage▾

The use of borrowed money to amplify potential investment returns. Leverage magnifies gains when things go well and magnifies losses when they go poorly. High leverage is the most common cause of corporate bankruptcy during economic downturns.

Real-life exampleA company that finances $1M of assets with $900K of debt and $100K of equity is using 9:1 leverage. If asset values fall 10%, equity is completely wiped out.

Liquidity▾

The ease and speed with which an asset or investment can be bought or sold in the market without causing a drastic change in its price.

Real-life exampleSelling a stock on your phone takes seconds because of high liquidity, whereas selling a physical house can take months.

Margin of Safety▾

The difference between a stock intrinsic value and its current market price, expressed as a percentage discount. First described by Benjamin Graham, it protects investors against errors in their own valuation assumptions.

Real-life exampleIf you estimate a company intrinsic value at $100 per share and buy at $65, your margin of safety is 35%. If your estimate was wrong and the company is actually worth $80, you still profit significantly.

Market CapitalizationMarket Cap▾

The total market value of a public company's outstanding shares, calculated by multiplying the current share price by the total number of shares.

Real-life exampleIf a company has 1 million shares and each share sells for $50, its Market Cap is exactly $50 million.

Medium of Exchange▾

One of the three main jobs of money. A medium of exchange is something universally accepted in trade, so you do not need to find someone who has exactly what you want and also wants exactly what you have.

Real-life exampleYou use dollars to buy coffee. The barista accepts dollars not because she personally wants dollars, but because she knows everyone else will accept them too.

Net Incomenet profit▾

A company total profit after subtracting every expense including cost of goods sold, operating expenses, taxes, and interest payments. Net income is the definitive answer to whether a business made money in a given period.

Real-life exampleA company with $500M in revenue but $510M in total costs has net income of -$10M. It is losing money despite massive sales.

Net Marginnet profit margin▾

Net income divided by revenue, expressed as a percentage. Net margin tells you how many cents of profit a company keeps from every dollar of revenue after all costs are paid.

Real-life exampleApple net margin is approximately 25%, meaning it keeps $0.25 of every revenue dollar as profit. A typical grocery store operates on net margins of 1-3%.

Network Effect▾

A phenomenon where a product becomes more valuable to each user as the total number of users increases. Network effects create powerful competitive moats because the value gap between the market leader and any challenger widens automatically as the leader grows.

Real-life exampleWhatsApp is more valuable to each user the more of their contacts are also on it. A competing app with superior features but zero of your contacts has effectively zero value to you.

Nominal vs. Real▾

Nominal means the number you see on paper, before adjusting for inflation. Real means what that number is actually worth in terms of buying power, after accounting for inflation.

Real-life exampleYour savings account grew by 2% this year. Inflation was 3.5%. Your nominal return was positive 2%. Your real return was negative 1.5%.

Operating Cash FlowOCF▾

The cash generated by a company core business operations. Operating cash flow excludes cash from investing and financing activities. Consistently positive OCF is the gold standard of business health.

Real-life exampleA company might report $80M in net income but only $30M in operating cash flow if customers are not paying invoices promptly or if there are large non-cash revenues.

P/E RatioPrice-to-Earnings▾

A valuation metric calculated by dividing a company's stock price by its annual earnings per share, showing how much investors pay for every $1 of profit.

Real-life exampleIf a stock costs $20 and earns $2 per share a year, its P/E Ratio is 10, meaning you pay $10 for every $1 of corporate profit.

Present ValuePV▾

The current worth of a future sum of money, discounted back at a required rate of return. A dollar today is worth more than a dollar in the future because today dollar can be invested and grow.

Real-life exampleAt a 10% discount rate, $110 received one year from now has a present value of exactly $100 today ($110 divided by 1.10). This is the mathematical foundation of all DCF-based valuation.

Price-to-Book RatioP/B▾

A valuation multiple calculated by dividing market capitalization by book value (shareholders equity). A P/B below 1.0x means the market values the company at less than its accounting net worth.

Real-life exampleA bank trading at 0.7x P/B means you can buy $1 of its accounting assets for just $0.70. Whether this is a bargain depends entirely on whether the assets are actually worth their stated book value.

Price-to-Earnings RatioP/E ratio▾

A valuation multiple calculated by dividing a company current share price by its annual earnings per share. It tells you how many dollars investors pay for every $1 of annual company profit.

Real-life exampleA stock at $50 with EPS of $2.50 has a P/E of 20x. If the industry average P/E is 15x, you are paying a 33% premium, which may or may not be justified by superior growth prospects.

Purchasing Power▾

The amount of goods and services your money can actually buy. Purchasing power decreases when inflation rises, because prices go up while your amount of money stays the same.

Real-life exampleIn 2000, $20 could buy you about 20 gallons of milk. Today, $20 buys you roughly 5 gallons. Its purchasing power has dropped dramatically.

Real Return▾

Your investment return after subtracting inflation. This is the only number that tells you whether you are actually getting wealthier.

Real-life exampleThe stock market has historically returned about 10% per year on average before inflation. After accounting for roughly 3% average inflation, the historical real return is closer to 7% per year.

Return on EquityROE▾

Net income divided by shareholders equity, expressed as a percentage. ROE measures how efficiently a company generates profit from each dollar of owner capital. Sustained high ROE above industry peers is one of the strongest signals of a durable competitive moat.

Real-life exampleIf a company earns $20M in net income with $100M in equity, its ROE is 20%. Buffett often uses ROE as a primary screen, he looks for companies sustaining 15% or higher ROE over many years.

Revenuetop line▾

The total amount of money a business collects from selling its products or services before subtracting any costs. Revenue is the starting point of the income statement.

Real-life exampleA company can have $1 billion in revenue and still lose money if its costs exceed that amount. Revenue growth without profitability is a warning sign, not a celebration.

Sensitivity Analysis▾

The practice of testing how dramatically a DCF valuation changes when key assumptions are adjusted. Sensitivity analysis reveals how much estimation error a valuation can tolerate before the investment thesis breaks.

Real-life exampleIf your DCF gives an intrinsic value of $100 per share at 10% growth, but only $65 per share at 7% growth, and the stock trades at $90, you do not have a margin of safety across the full range of plausible scenarios.

Shareholders' Equitybook value▾

The residual interest in a company assets after all liabilities are paid, what the owners actually own. Calculated as Total Assets minus Total Liabilities. Growing shareholders equity over time is the fundamental measure of wealth creation.

Real-life exampleIf a company has $1 billion in assets and $700 million in liabilities, shareholders equity is $300 million. Each share represents a proportional claim on that $300 million.

Store of Value▾

One of the three main jobs of money. A store of value is something that holds its worth over time, so you can save it today and use it later without it losing value.

Real-life exampleGold has served as a store of value for thousands of years. You could bury a gold coin in 1500 and dig it up today and it would still buy you something.

Switching Cost▾

The financial, operational, or psychological cost a customer incurs when changing from one product to another. High switching costs create a competitive moat by making it economically irrational to switch even when a cheaper alternative exists.

Real-life exampleEnterprise software embedded in a company payroll, billing, and supply chain has switching costs so high that even a 30% cheaper competitor rarely wins the account.

Tax▾

A compulsory financial charge imposed by a government on individuals or businesses to fund public services and infrastructure.

Real-life exampleWhen the fishing company pays a portion of its corporate earnings to the government at the end of the year, it is paying a tax.

Terminal ValueTV▾

In a DCF model, the estimated present value of all cash flows beyond the explicit projection period, assumed to grow at a stable long-term rate in perpetuity. Terminal value often represents 60-80% of total intrinsic value.

Real-life exampleIf a business is projected to generate $50M in free cash flow in Year 10, growing at 3% per year forever with a 10% discount rate, the terminal value = $50M times 1.03 divided by (0.10 - 0.03) = $736M in present value terms.

Time Value of MoneyTVM▾

The principle that a dollar available today is worth more than a dollar promised in the future, because today dollar can be invested to earn a return. This concept is the mathematical foundation of all investment valuation.

Real-life exampleIf you can earn 8% per year, receiving $100 today is equivalent to receiving $108 in exactly one year. Choosing correctly between the two requires understanding the time value of money.

Unit of Account▾

One of the three main jobs of money. A unit of account is a standard way to measure and compare the value of different things. It lets everyone quote prices in the same terms.

Real-life exampleBecause of the dollar as a unit of account, you know immediately that a $50 shirt costs twice as much as a $25 book.

Volumetrading volume▾

The number of shares of a stock bought and sold during a given trading session. Comparing today volume to average volume reveals whether trading activity is unusually high or low, and often signals whether significant news is driving the price move.

Real-life exampleA stock dropping 8% on 15 times its average volume almost always signals a major negative catalyst. The same 8% drop on normal volume carries a very different meaning.
