Foundational Stock Market Primer

Overview

This lesson introduces 100+ foundational stock market terms, organized into nine topics for beginners.

Stocks, Ownership, and Portfolios

• A stock represents ownership in a company; you own a piece of the business.
• Common stock offers profit claims and voting rights; dividends not guaranteed.
• Preferred stock usually has no voting rights; higher dividend priority and payout priority.
• A portfolio is the collection of all investments you hold.
• Dividends are company profit distributions paid to shareholders.
• Public companies list shares on exchanges; private companies are owned by founders or investors.
• An index tracks a basket of stocks and serves as a performance benchmark.
• Beating the market means outperforming a major index, typically the S&P 500.

Exchanges, Brokers, and Trading Basics

• A stock exchange is the marketplace where stock trading occurs.
• A brokerage connects investors to exchanges and may charge commissions.
• Ticker symbols are short codes identifying stocks (e.g., AAPL, TSLA).
• Market hours are typically 9:30 a.m.–4:00 p.m. Eastern Time.
• Opening price is the first trade price; closing price is the final trade price.
• Pre-market and after-hours sessions allow trading outside normal hours with lower liquidity.
• Volume measures number of shares traded; higher volume means more activity.
• Liquidity is ease of trading without significantly moving the price.

Company Value, Financials, and Key Ratios

• Market capitalization = stock price × shares outstanding.
• Enterprise value includes market cap, debt, and cash for a fuller worth picture.
• Revenue is total sales; net income is profit after all expenses.
• Assets are owned resources (cash, equipment); liabilities are obligations (loans, debt).
• Earnings per share (EPS) = net income ÷ shares; profit per share indicator.
• Price-to-earnings (P/E) compares price to EPS; gauges valuation vs. profits.
• PEG ratio adjusts P/E for expected growth; helps assess growth stock valuation.
• Dividend yield = annual dividends ÷ stock price; income measure.
• Free cash flow is cash remaining after expenses and investments for dividends or growth.
• Gross margin = (sales − direct costs) ÷ sales; production efficiency.
• Operating margin reflects profit after operating expenses like salaries and rent.
• Net profit margin = net income ÷ revenue; bottom-line profitability.

Stock Categories and Sizes

• Growth stocks expect rapid expansion; often reinvest profits instead of dividends.
• Value stocks appear cheap vs. fundamentals; investors expect revaluation.
• Blue chips are large, established, reputable firms; considered stable and reliable.
• Cyclical stocks move with the economy; do well in booms, struggle in recessions.
• Defensive stocks sell essentials; more stable across economic cycles.
• Market cap sizes: large cap > $10B; mid cap $2–$10B; small cap < $2B.
• Penny stocks trade at low prices, usually under $5; highly speculative and risky.

Funds, Accounts, and Other Asset Classes

• Mutual funds pool investor money; professional managers select investments.
• ETFs are funds that trade like stocks; can be bought and sold during market hours.
• Index funds (mutual funds or ETFs) track market indexes to match performance at low cost.
• Hedge funds use strategies like short selling and leverage; higher risk, for wealthy investors.
• Roth IRA allows after-tax contributions; investment growth and retirement withdrawals are tax-free.
• Commodities include gold, oil, and agricultural products; invest directly or via funds.
• Bonds are loans to issuers with interest payments and principal returned at maturity.
• Currencies enable investing in foreign money like dollars, euros, or yen.
• Cryptocurrencies like Bitcoin and Ethereum are digital assets trading independently.

Market Behavior and Sentiment

• Volatility measures price fluctuation magnitude; high volatility means larger swings.
• VIX gauges expected 30-day S&P 500 volatility; higher VIX implies bigger expected moves.
• Bull market features prolonged rising prices and optimism.
• Bear market features falling prices and pessimism.
• A correction is a temporary drop, typically around 10% from recent highs.
• A rally is a sharp price rise following a decline.
• A crash is a sudden, severe market drop driven by panic or major events.
• A bubble is price inflation far above value due to speculation; eventually bursts.
• Market sentiment is overall investor mood; can drive trends beyond fundamentals.

Investing Approaches and Analysis

• Passive investing buys broad indexes and holds long term; low cost and market-matching.
• Dollar-cost averaging invests fixed amounts regularly; smooths volatility over time.
• Lump-sum investing puts a large amount in at once; faster growth potential, higher timing risk.
• Active investing selects stocks or times markets to outperform averages.
• Buy the dip purchases after price drops, expecting recovery.
• Buy and hold owns quality companies for years to benefit from compounding.
• Market timing tries to predict entry and exit points; very difficult and risky.
• Fundamental analysis evaluates financials, management, and industry factors.
• Technical analysis studies price charts and trends to forecast movements.
• Macro analysis examines economy, rates, and global trends to guide decisions.

Corporate Actions and Key Dates

• Initial public offering (IPO) sells shares to the public for the first time.
• Secondary offering issues additional shares to raise more capital.
• Buyback (share repurchase) reduces shares outstanding; can boost remaining share value.
• Stock split increases shares and lowers price proportionally (e.g., 2-for-1 halves price).
• Reverse split combines shares to raise price, often to meet exchange standards.
• Acquisition occurs when one company purchases another; impacts both stock prices.
• Ex-dividend date is the cutoff to receive the next dividend.
• Payment date is when the dividend is sent to shareholders.
• Insiders include executives or directors with non-public information; trades are monitored.

Portfolio Construction, Risk, and Performance

• Diversification spreads investments to reduce impact from any single holding’s loss.
• Asset allocation divides money among stocks, bonds, and cash based on goals and risk tolerance.
• Rebalancing restores target allocation after uneven asset growth.
• Alpha measures outperformance or underperformance versus a benchmark.
• Beta measures sensitivity to market movements; higher beta implies more volatility.
• Sharpe ratio measures return per unit of risk; higher values indicate better risk-adjusted returns.
• Correlation indicates how closely assets move together; affects diversification benefits.
• Systematic risk affects the entire market; cannot be diversified away.
• Unsystematic risk is company or sector specific; can be reduced via diversification.

Economic Concepts and Policy Tools

• Inflation is a general rise in prices, reducing purchasing power over time.
• Deflation is a general fall in prices, which can slow economic growth.
• Stagflation is rising prices with stalled growth and high unemployment.
• A recession is an economic contraction over several months, often with falling GDP.
• Monetary policy by central banks adjusts interest rates and money supply.
• Fiscal policy uses government spending and taxes to influence economic activity.

Key Terms & Definitions

Action Items / Next Steps

• Compare index, mutual fund, and ETF structures; note trading and cost differences.
• Draft a basic asset allocation aligned with risk tolerance and goals.
• Set a schedule for regular contributions using dollar-cost averaging.
