The stock market is a marketplace where buyers and sellers trade shares of publicly listed companies. It includes exchanges like the NSE & BSE, and serves as a key mechanism for companies to raise capital and for investors to grow wealth over time.

To start: (1) Set a financial goal, (2) Open a brokerage account, (3) Fund it with money you can afford to invest, (4) Research stocks or index funds, (5) Start small and diversify. Many brokers offer Low brokerage trades for beginners.

A stock is a unit of ownership in a company. When you buy a stock, you become a partial owner (shareholder) and may benefit from its growth through price appreciation and dividends.

Stocks represent ownership in a company — higher risk, higher potential return. Bonds are loans you give to companies or governments in exchange for regular interest payments — generally lower risk, lower return.

A bull market is a period when stock prices are rising or expected to rise, typically 20%+ from recent lows. It reflects investor optimism, strong economic growth, and high demand for equities.

A bear market is a period of falling prices — generally 20% or more from recent highs. It often signals economic slowdown, low investor confidence, and widespread selling pressure.

An Exchange-Traded Fund (ETF) is a basket of securities — stocks, bonds, or commodities — that trades on a stock exchange like a single stock. ETFs offer diversification, low costs, and flexibility, making them popular for beginners and experts alike.

A mutual fund pools money from many investors to buy a diversified portfolio of assets. It is managed by a professional fund manager and priced once per day after market close, unlike ETFs which trade throughout the day.

The S&P 500 tracks the 500 largest publicly traded U.S. companies by market cap. It is widely considered the best single benchmark of U.S. stock market performance and the overall health of the American economy.

A dividend is a portion of a company’s earnings paid out to shareholders, usually quarterly. Not all companies pay dividends — they are most common among large, stable companies in utilities, financials, and consumer staples.

Market cap = share price × total shares outstanding. Companies are classified as large-cap (>$10B), mid-cap ($2B–$10B), and small-cap (<$2B). Larger companies generally carry lower risk but less growth potential.

An Initial Public Offering (IPO) is the first time a private company offers its shares to the public on a stock exchange. It allows the company to raise capital and gives early investors an exit opportunity.

A stock split increases the number of shares by dividing each existing share. For example, a 2-for-1 split doubles shares and halves the price. The total company value doesn’t change — it just makes shares more accessible.

Blue-chip stocks are shares of large, well-established, financially stable companies with long records of reliable performance. Examples include Apple, Johnson & Johnson, and Coca-Cola. They are considered lower-risk investments.

NYSE is a traditional auction-based exchange with physical floor traders, focusing on large established companies. NASDAQ is fully electronic and known for listing technology companies. Both list thousands of stocks but differ in structure and culture.

Day trading involves buying and selling within the same trading day, with all positions closed before market close. It requires fast decision-making, skill, and strict risk management. Most beginners lose money day trading.

Swing trading holds positions for several days to weeks, profiting from short- to medium-term price moves. It requires less screen time than day trading while remaining more active than long-term investing.

Investing is a long-term approach focused on building wealth over years or decades. Trading seeks to profit from short-term price fluctuations. Investing requires less time and emotional discipline; trading demands constant attention and strict risk management.

DCA involves investing a fixed amount at regular intervals regardless of price. This reduces the impact of volatility and removes the pressure of timing the market — one of the most beginner-friendly strategies.

Passive investing means buying and holding diversified index funds or ETFs without trying to beat the market. It minimizes costs, reduces emotional decisions, and historically outperforms most actively managed funds over 10+ years.

Active investing involves frequent buying and selling with the goal of outperforming a benchmark. It requires research, timing, and monitoring. Most studies show active funds underperform index funds after fees over the long run.

Buffett follows a value investing approach: buying high-quality businesses at fair or undervalued prices and holding long term. Key principles: competitive advantages (moats), strong management, predictable earnings, and avoiding excessive debt.

“Buy the dip” means purchasing a security after a price drop, betting the decline is temporary. It works well in bull markets but can be dangerous if the asset is in a genuine downtrend — dips can become deeper crashes.

Short selling involves borrowing shares and selling them, hoping the price falls so you can repurchase cheaper. It’s high risk because losses are theoretically unlimited — stock prices can rise indefinitely.

Sector rotation is shifting investment money between industry sectors as economic conditions change. For example, rotating from tech to energy during inflationary periods. Understanding the economic cycle helps predict sector outperformance.

Growth stocks have high expected earnings growth — often high P/E, low dividends (e.g., tech). Value stocks trade below intrinsic worth and often pay dividends. A balanced portfolio often holds both styles.

There is no universally “best” time. Long-term investors benefit from consistent investing over time (DCA). Buying during market dips has historically rewarded patient investors. For day traders, the first and last hours of trading offer the most volatility.

Rebalancing realigns your portfolio back to its target asset allocation by selling overweighted assets and buying underweighted ones. This is typically done annually or when allocations drift by 5%+, maintaining your desired risk level.

Technical analysis studies historical price and volume data using charts and indicators to forecast future price movements. Common tools include moving averages, RSI, MACD, support/resistance levels, and candlestick patterns.

A candlestick shows the open, high, low, and close for a given period. The body shows the open-to-close range; wicks show highs and lows. Patterns like doji, hammer, and engulfing signal potential reversals.

Support is a price level where buying interest prevents further decline. Resistance is where selling pressure prevents further rise. These levels are foundational in technical analysis for identifying entry and exit points.

A moving average smooths price data over a period (e.g., 50-day, 200-day) to identify trends. SMA gives equal weight to all periods; EMA weights recent prices more heavily. Crossovers between MAs signal buy/sell opportunities.

RSI is a momentum oscillator (0–100) measuring the speed of price changes. Above 70 = overbought (potential sell); below 30 = oversold (potential buy). It helps identify reversals and momentum shifts.

MACD (Moving Average Convergence Divergence) shows the relationship between two EMAs (12-day & 26-day). A signal line (9-day EMA) is plotted alongside. Crossovers and divergences are used as buy/sell signals.

Bollinger Bands = middle SMA + two bands set 2 standard deviations above and below. Price at the upper band may be overbought; at the lower, oversold. Band squeezes often precede major breakouts.

Fibonacci retracement uses horizontal lines at key ratios — 23.6%, 38.2%, 50%, 61.8%, 78.6% — of a prior price move to identify potential support and resistance. Traders use these as reversal zones during corrections.

A breakout occurs when price moves above resistance or below support on high volume, signaling a potential new trend. Traders enter at breakouts expecting significant directional moves. False breakouts (fakeouts) are a common risk.

The 52-week high/low represents the highest and lowest price a stock traded over the past year. These often act as psychological support and resistance levels. Breaking a 52-week high on strong volume can signal powerful upside momentum.

A dead cat bounce is a temporary recovery in a declining stock, followed by continued downside. The name comes from the idea that “even a dead cat will bounce if it falls from a great height.” Traders use it to describe false recoveries.

Volatility measures the degree of price fluctuation in a market or security. High volatility = large swings; low volatility = stable prices. The VIX index measures expected S&P 500 volatility over the next 30 days.

The VIX (CBOE Volatility Index) measures expected 30-day market volatility derived from S&P 500 options. Above 30 = fear/uncertainty; below 15 = complacency. Often called the “fear gauge” of Wall Street.

A stock screener filters stocks by specific criteria — P/E ratio, market cap, dividend yield, sector, revenue growth. Popular tools include Finviz, TradingView, Yahoo Finance Screener, and broker-built platforms.

Backtesting tests a trading strategy on historical price data to see how it would have performed. It validates strategies before risking real capital. However, past performance doesn’t guarantee future results — markets change.

Fundamental analysis evaluates a company’s financial health, business model, industry position, and economic environment to determine intrinsic value. Investors compare this to the current price to decide if the stock is over- or undervalued.

The Price-to-Earnings (P/E) ratio = share price ÷ earnings per share. A high P/E suggests investors expect strong future growth; a low P/E may indicate undervaluation. It is one of the most widely used valuation metrics.

EPS = net profit ÷ total shares outstanding. It indicates how much profit a company generates per share. Rising EPS over time typically signals a healthy, growing company. It’s often paired with the P/E ratio to assess stock value.

Intrinsic value is the true fundamental worth of a stock based on financial analysis, independent of its market price. Value investors buy stocks trading below intrinsic value — the concept known as the “margin of safety.”

A balance sheet shows a company’s assets, liabilities, and shareholders’ equity. Key things to analyze: total debt vs. total assets, current ratio (current assets ÷ current liabilities), and equity growth over time.

Free cash flow (FCF) is cash generated after capital expenditures. It represents money available for dividends, buybacks, debt repayment, or reinvestment. Many investors prefer FCF over reported earnings as it’s harder to manipulate.

Earnings reports are quarterly financial statements showing revenue, expenses, profit, and guidance. Beats or misses vs. analyst expectations often trigger large price swings — they are among the most market-moving events for individual stocks.

Book value = total assets minus total liabilities. The P/B ratio compares market price to book value. Stocks trading below book value may be considered undervalued and are often targeted by value investors.

A buyback occurs when a company uses cash to repurchase its own shares, reducing shares outstanding. This increases EPS and often boosts price. It’s a tax-efficient way to return value to shareholders compared to dividends.

A competitive moat is a durable advantage that protects a company from competitors — like brand strength (Coca-Cola), network effects (Facebook), low-cost production, or switching costs. Companies with wide moats tend to maintain profitability for longer.

Growth investments (tech stocks) aim to increase capital over time by reinvesting earnings. Income investments (dividend stocks, bonds) generate regular cash flow. Most balanced portfolios include both depending on life stage and goals.

ESG (Environmental, Social, Governance) investing considers non-financial factors alongside financials. ESG investors seek companies with strong environmental practices, ethical social policies, and sound governance. ESG funds have become mainstream globally.

Risk management involves strategies to limit potential losses — using stop-losses, appropriate position sizing, diversifying trades, and never risking more than 1–2% of capital on a single trade. It separates consistent traders from those who blow up accounts.

A stop-loss automatically sells a security when it hits a specified price, limiting potential loss. It removes emotion from trading and protects capital during adverse moves. It is one of the most fundamental risk management tools.

A trailing stop adjusts upward as price rises. E.g., a 10% trailing stop on a $100 stock sets stop at $90. If the stock rises to $120, stop moves to $108. This locks in profits while letting winning trades run.

The risk/reward ratio compares potential loss to potential gain. A 1:3 ratio means you risk $1 to potentially gain $3. Successful traders typically aim for at least 1:2 to remain profitable even with a win rate below 50%.

Position sizing determines how much capital to allocate to a single trade. A common rule is to risk no more than 1–2% of total capital per trade. Proper sizing ensures a series of losses won’t significantly damage your overall account.

A trading plan is a documented set of rules for entering, exiting, and managing trades. It includes your strategy, risk tolerance, criteria, position sizing, and review process. Trading with a plan removes emotion and improves consistency.

Diversification means spreading investments across different assets, sectors, and geographies to reduce risk. Poor performance in one area is offset by better performance in another, reducing overall portfolio volatility.

Asset allocation divides investments among stocks, bonds, cash, and real estate based on goals, risk tolerance, and time horizon. It is considered one of the most important determinants of long-term portfolio performance.

A trading journal logs every trade — entry/exit, size, rationale, emotions, and outcome. Reviewing it regularly identifies strengths, weaknesses, and recurring mistakes. It is one of the most effective tools for improving performance.

Leverage allows control of a larger position than your capital by borrowing. 10:1 leverage means $1,000 controls $10,000. It magnifies gains equally as losses and can result in losing more than your initial investment.

Options are contracts giving the buyer the right — not obligation — to buy (call) or sell (put) an asset at a set price before expiry. Used for hedging, speculation, or income generation through strategies like covered calls.

A call option gives the right to buy an asset at the strike price before expiry. Traders buy calls when they expect a stock to rise. If the stock exceeds the strike price, the call gains value. If not, the buyer loses only the premium paid.

A put option gives the right to sell an asset at the strike price before expiry. Traders buy puts as a bearish bet or to hedge against declining prices. If the stock falls below the strike, the put gains in value.

Futures are contracts to buy or sell an asset at a set price on a future date. Used for commodities (oil, gold, wheat), currencies, and indices. Both hedgers (risk management) and speculators (profit from price moves) use futures.

A market order executes immediately at the best available price. A limit order only executes at your specified price or better. Limit orders give price control but may not fill; market orders guarantee execution but not price.

A Real Estate Investment Trust (REIT) owns income-producing real estate and trades on stock exchanges. REITs must distribute at least 90% of taxable income as dividends, giving individual investors real estate exposure without owning property.

An index fund passively tracks a market index like the S&P 500. Instead of trying to beat the market, it mirrors the index. Known for low fees, broad diversification, and outperforming most actively managed funds long-term.

Bond yield is the return earned from holding a bond. It is inversely related to bond price — when prices rise, yields fall, and vice versa. The 10-year U.S. Treasury yield is a key benchmark for interest rates globally.

Pre-market (4–9:30 AM ET) and after-hours (4–8 PM ET) trading have lower volume, wider spreads, and higher volatility. Most activity is driven by earnings reports or major economic news released outside regular trading hours.

Penny stocks trade below $5 per share, typically on OTC markets. They carry extreme risks: low liquidity, limited disclosure, and vulnerability to pump-and-dump schemes. Generally unsuitable for beginner investors.

A margin account lets investors borrow money from their broker to buy more securities. While it amplifies potential gains, it equally amplifies losses. If the account falls below the maintenance margin, a margin call requires you to deposit more funds or sell assets.

A recession is defined as two or more consecutive quarters of negative GDP growth. Stock markets typically fall as corporate earnings drop and investor confidence declines. However, markets often begin recovering before the economy fully rebounds.

Inflation is the rate at which prices rise, eroding purchasing power. It hurts bonds and cash savings but may benefit stocks, real estate, and commodities. Investors often seek inflation-hedging assets (TIPS, gold, energy stocks) during high-inflation periods.

The Federal Reserve is the U.S. central bank that sets monetary policy including interest rates. Rate hikes slow growth and pressure stocks; rate cuts stimulate the economy and often boost equities. Fed announcements are among the most market-moving events in finance.

Rising rates increase borrowing costs, reduce consumer spending, and make bonds more attractive — all of which pressure stock prices. Growth stocks are especially sensitive because their valuations rely on future earnings discounted at current rates.

QE is when central banks buy financial assets to inject money into the economy, lowering interest rates and increasing money supply. It typically boosts asset prices. The opposite, quantitative tightening (QT), reduces the money supply and can pressure markets.

A crash is a rapid, severe drop of 10%+ in a matter of days. Famous crashes include Black Tuesday (1929), Black Monday (1987), the 2008 financial crisis, and the COVID crash (March 2020). Crashes are terrifying in the moment but often present generational buying opportunities.

Interest rate risk is the risk that rising rates will reduce the value of investments, particularly bonds. When rates rise, existing bond prices fall. Stocks in rate-sensitive sectors like real estate and utilities also tend to decline.

A correction = 10–20% decline from a recent high — relatively common (roughly once per year). A crash = sudden drop of 20%+ in a very short time — rare, severe, and often driven by major systemic shocks.

EMH states that stock prices always fully reflect all available information, making it impossible to consistently beat the market. Critics point to market anomalies and behavioral biases as evidence against perfect market efficiency.

A brokerage account lets you buy and sell stocks, bonds, ETFs, and other securities through a licensed broker. Unlike retirement accounts, there are no contribution limits, but gains are subject to capital gains tax.

A Roth IRA is funded with after-tax dollars. Investments grow tax-free and qualified retirement withdrawals are also tax-free. In 2024, the annual contribution limit is $7,000 ($8,000 if age 50+).

A 401(k) is an employer-sponsored retirement account funded with pre-tax income. Many employers match a percentage of contributions. Funds grow tax-deferred until withdrawal, typically starting at age 59½.

Capital gains tax is owed on profit from selling assets. Short-term gains (held <1 year) are taxed as ordinary income. Long-term gains (held 1+ year) are taxed at preferential rates: 0%, 15%, or 20% depending on income.

Tax-loss harvesting means selling investments at a loss to offset capital gains, reducing tax liability. To avoid the wash sale rule, you must wait 30 days before buying back the same or substantially identical security.

The wash sale rule prevents claiming a tax loss if you buy the same or substantially identical security within 30 days before or after selling at a loss. It is designed to prevent artificial tax-loss harvesting without genuinely exiting a position.

SIPC protects customers of member brokerage firms if the firm fails financially, covering up to $500,000 in securities (including $250,000 in cash). It does not protect against market losses — only broker insolvency.

Behavioral finance studies how psychological biases influence investor decisions and market outcomes. Common biases include loss aversion, overconfidence, herd mentality, and confirmation bias. Understanding them helps investors make more rational decisions.

Herd mentality is the tendency to follow the crowd rather than make independent decisions. It fuels bubbles during euphoric markets and panic selling during crashes. Contrarian investors actively bet against herd behavior.

CNN’s Fear and Greed Index measures investor sentiment from 0 (extreme fear) to 100 (extreme greed). Extreme fear may signal buying opportunities; extreme greed may indicate an overheated market. It’s derived from 7 indicators including momentum and safe haven demand.

Market sentiment is the overall attitude of investors toward a market or security. Driven by emotions, news, and economic data. Measured by indicators like the Fear & Greed Index, put/call ratio, and short interest. Sentiment often overshoots fundamentals in both directions.

Algorithmic (algo) trading uses computer programs to execute trades automatically based on pre-set criteria. Used by hedge funds and institutions to exploit price inefficiencies at high speed. High-frequency trading (HFT) is an extreme form executing millions of trades per second.

A hedge fund is a private investment partnership using advanced strategies — leverage, short selling, derivatives, and arbitrage — to generate returns in any market direction. Typically restricted to accredited investors due to high minimums and risk levels.

The PDT rule requires 4+ day trades within 5 business days in a margin account to maintain a minimum $25,000 balance. Violating this results in a 90-day trading restriction. It primarily affects small U.S. retail traders.

Insider trading is trading on material, non-public information — e.g., knowing about an unannounced acquisition before it’s public. It is illegal because it gives unfair advantage, undermines market integrity, and is enforced by the SEC. Penalties include fines, profit disgorgement, and prison sentences.
