BUSINESS & ENTREPRENEURSHIP
Business Model — How a company creates, delivers, and captures value. Examples: subscription, freemium, marketplace, advertising, licensing.
Value Proposition — The specific benefit or problem a product/service solves for customers. What makes it worth buying.
Competitive Advantage — A unique strength or resource that makes a business harder to replicate than competitors. Can be cost, quality, brand, network effects, or proprietary technology.
Moat — A sustainable competitive advantage that protects a business from competition. Like a castle moat—hard for competitors to cross.
Scalability — How easily a business can grow without proportional increases in costs. Software scales better than services.
Pivot — Changing strategy or business direction based on market feedback without abandoning the core mission.
Go-to-Market (GTM) — The strategy and plan for launching a product or service and acquiring customers. Includes pricing, distribution, and marketing.
Market Fit — When a product solves a real customer problem so well that demand grows naturally. Signs: strong retention, word-of-mouth growth, willingness to pay.
Runway — How long a company can operate with existing capital before running out of money.
Burn Rate — How quickly a company spends cash. If you burn $100k/month with $1M in the bank, you have 10 months of runway.
Unit Economics — The profitability of a single customer or transaction. Key metric: Customer Lifetime Value (LTV) vs. Customer Acquisition Cost (CAC).
Bootstrap — Starting and growing a business with personal funds or revenue, without external investment.
VC/Venture Capital — Investment in high-growth, high-risk startups in exchange for equity ownership.
Due Diligence — Investigating a company's financials, operations, and risks before investing or acquiring it.
Exit — Selling a company to another buyer (acquisition) or going public (IPO). What investors hope for as return on investment.
Stakeholder — Anyone with an interest in a company: employees, customers, investors, regulators, suppliers.
INVESTING & FINANCE
Asset Class — A category of investments: stocks, bonds, real estate, commodities, currencies.
Equity — Ownership stake in a company. Stock is equity. Common in startup funding: "2% equity" means 2% ownership.
Dividend — Cash payment a company distributes to shareholders from profits.
Blue Chip — Large, established, financially stable companies with long histories. Lower risk, typically lower growth.
Market Capitalization (Market Cap) — Total value of a company's stock. Stock price × total shares outstanding. Measure of company size.
P/E Ratio (Price-to-Earnings) — Stock price divided by annual earnings per share. High P/E = investors expect future growth. Low P/E = potentially undervalued or slow growth.
Book Value — Total assets minus liabilities. What a company is "worth on the books."
Return on Equity (ROE) — Net profit divided by shareholder equity. How efficiently a company uses shareholder money to generate profit.
Free Cash Flow (FCF) — Cash generated by operations minus capital expenditures. More honest than accounting profit; hard to fake.
Working Capital — Current assets minus current liabilities. Cash available to run day-to-day operations.
Leverage — Using borrowed money to amplify returns (or losses). High leverage = high risk, high reward potential.
Margin — Profit as a percentage of revenue. Gross margin, operating margin, net margin measure different levels of profitability.
Liquidity — How easily an asset can be converted to cash. Stocks are liquid; real estate is illiquid.
Volatility — How much an investment's price fluctuates. High volatility = high risk and high potential reward.
Beta — How much a stock moves relative to the overall market. Beta of 1 = moves with the market. Beta of 2 = twice as volatile.
Diversification — Spreading investments across different assets to reduce risk. Reduces volatility but may cap returns.
Bull Market — Rising prices, investor optimism, economic expansion. Opposite: Bear Market (falling prices, pessimism).
IPO (Initial Public Offering) — A company's first public stock offering, transitioning from private to public.
Valuation — Estimation of what a company is worth. Methods: discounted cash flow, comparable companies, asset-based.
Due Diligence — Deep investigation of a company's finances, operations, risks before investing.
Fundamental Analysis — Evaluating investment value based on financial statements, business quality, competitive position, management.
Technical Analysis — Predicting price movements based on historical price and volume patterns. Controversial effectiveness for long-term investing.
Earnings Per Share (EPS) — Net income divided by shares outstanding. Higher EPS = more profit per share.
Debt-to-Equity Ratio — Total debt divided by shareholder equity. Measure of financial leverage and risk.
Treasury/Cash Reserves — Cash on a company's balance sheet. Higher reserves = more financial flexibility and safety.
Opportunity Cost — The value of the next best alternative foregone. If you invest in X, the opportunity cost is returns from Y you didn't do instead.
PSYCHOLOGY & BEHAVIORAL ECONOMICS
Cognitive Bias — Systematic errors in thinking that lead to flawed judgment. We all have them.
Halo Effect — Judging someone/something overall based on one positive trait or limited information. "He's smart, so he must be good at everything."
Confirmation Bias — Seeking information that confirms existing beliefs and ignoring contradictory evidence.
Sunk Cost Fallacy — Continuing something because of past investment ("I've spent so much already") rather than future value.
Anchoring — Over-relying on the first number you see. If you see $100, you anchor to that and judge $80 as cheap.
Availability Heuristic — Judging likelihood based on how easily examples come to mind. Plane crashes feel common because they're vivid; car accidents are common but forgettable.
Loss Aversion — Fearing losses more than valuing equivalent gains. Lose $100 feels worse than gaining $100 feels good.
Status Quo Bias — Preferring the current state over change, even if change would be beneficial.
Recency Bias — Over-weighting recent events in decisions. One bad quarter can erase a year of good performance in your mind.
Overconfidence Bias — Overestimating your knowledge, skill, or ability to predict outcomes.
Dunning-Kruger Effect — Incompetent people overestimating their competence; experts underestimating theirs.

Framing Effect — Same information presented differently leads to different decisions. "90% success rate" vs. "10% failure rate" feel different.
Survivorship Bias — Focusing on successful cases while ignoring failures. "These successful investors all did X" ignores those who did X and failed.
Attribution Bias — Attributing others' failures to character ("They're lazy") but your own to circumstances ("I was tired").
FOMO (Fear of Missing Out) — Anxiety that others are having better experiences. Drives poor investment decisions and social media addiction.
Intrinsic vs. Extrinsic Motivation — Doing something for internal satisfaction vs. external reward. Research shows intrinsic is more sustainable.
Pygmalion Effect — High expectations lead to better performance. Believing in someone makes them perform better.
Incentive Misalignment — When someone's incentives don't align with desired outcomes. E.g., paying salespeople purely on volume encourages low-quality sales.

Outlier — Data point that's far from others. Can reveal insights or signal errors.
Trend — Direction of change over time. Distinguish from noise (random fluctuation).
Cohort — Group of people sharing a characteristic (e.g., all users who signed up in January 2024).
Retention Curve — Percentage of a cohort that stays over time. Steep drops reveal problems.
Churn — Percentage of customers who stop using a service. Opposite of retention.
Attribution — Assigning credit for outcomes to specific actions or channels. Complex because multiple touchpoints usually contribute.

FINANCIAL STATEMENTS & ACCOUNTING
Income Statement — Shows revenue, costs, and profit over a period. "Did we make money this quarter?"
Balance Sheet — Snapshot of assets, liabilities, and equity at a point in time. "What do we own and owe right now?"
Cash Flow Statement — Tracks actual cash coming in and going out. More honest than accounting profit because you can't spend revenue, only cash.
EBITDA — Earnings before Interest, Taxes, Depreciation, and Amortization. Common measure of operating profitability.
GAAP (Generally Accepted Accounting Principles) — Standard rules for financial reporting. What companies must follow.
Accrual Accounting — Recording revenue/expenses when earned/incurred, not when cash changes hands. Required for public companies. Can mask cash problems.

Audit — Independent verification of financial statements. Assurance they're accurate.
Provision — Money set aside for potential future losses (bad debts, warranty claims).
Write-Off — Declaring an asset worthless on the books. Tax deduction but signals problems.

Win-Win — Both parties benefit. Requires understanding each side's actual interests, not just stated positions.
Anchoring — The first number mentioned shapes expectations. If hiring, the first salary suggestion anchors the negotiation.
Precedent — What was agreed before. Strong negotiating tool: "We did this for X, so Y deserves the same."
Contingency — Payment or outcome dependent on future events. Example: "We'll pay more if you hit targets."
Non-Compete — Agreement not to compete in a specific market or time period.
IP (Intellectual Property) — Patents, copyrights, trademarks protecting creative work or inventions.
Indemnification — One party agrees to cover losses for the other. Common in contracts.
