Essential Stock Market Terms (A–Z)
1. Stock
A stock (or share or equity) is a unit of ownership in a company. When you buy a stock, you own a piece of that business and may benefit from its success through rising share prices and dividends.
2. Index
An index is a group of stocks used to represent a portion of the market. Common examples include the S&P 500 (U.S. large caps), ASX 200 (Australia), and the Nasdaq (tech-heavy companies).
3. ETF (Exchange-Traded Fund)
An ETF is a fund that owns a basket of stocks or bonds and trades on the stock exchange like a single stock. ETFs offer easy diversification and low costs.
4. IPO (Initial Public Offering)
An IPO is when a private company first sells shares to the public. It’s how companies “go public” and get listed on a stock exchange.
Understanding the IPO process step by step:
The company prepares financials and files with regulators.
Investment banks set the offering price.
Shares are sold to institutional investors and then to retail investors.
The company lists on an exchange, and shares begin trading.
5. EPS (Earnings Per Share)
EPS shows how much profit a company earns for each share outstanding. Calculated as:
EPS = Net Income / Number of Shares
A rising EPS is often a good sign for investors.
6. P/E Ratio (Price-to-Earnings Ratio)
The P/E ratio compares a company’s share price to its EPS. It helps investors judge if a stock is “expensive” or “cheap” compared to its earnings.
High P/E: Investors expect fast future growth.
Low P/E: May be undervalued, but check why it’s low.
7. Beta
Beta measures a stock’s volatility compared to the market (which has a Beta of 1).
Beta > 1: More volatile than the market
Beta < 1: Less volatile
Beta = 1: Same as market
Beta helps assess risk when building your portfolio.
8. Market Capitalization (Market Cap)
Market cap is the total value of a company’s outstanding shares:
Market Cap = Share Price x Total Shares
Large-cap: $10 billion+
Mid-cap: $2–10 billion
Small-cap: <$2 billion
9. Dividend
A dividend is a cash payment to shareholders, usually from company profits. Not all stocks pay dividends.
10. Bull Market
A bull market is a period when stock prices are rising, often accompanied by optimism and strong economic growth.
11. Bear Market
A bear market is when stock prices fall 20% or more from recent highs, often driven by fear or economic downturns.
12. Blue-Chip Stock
A blue-chip stock belongs to a large, established, financially sound company with a history of reliable performance (e.g., Apple, Johnson & Johnson).
13. Volatility
Volatility refers to how much a stock’s price swings up and down. High volatility = bigger price moves, higher risk.
14. Yield
Yield usually refers to the dividend yield—how much cash a stock pays each year relative to its price.
Dividend Yield = Annual Dividend / Share Price
15. Portfolio
Your portfolio is your collection of investments (stocks, ETFs, bonds, cash, etc.).
16. Order Types
Market Order: Buys or sells at the current price.
Limit Order: Sets a specific price to buy or sell.
Stop-Loss Order: Sells automatically if the price drops to a set level.
17. Volume
Volume is the number of shares traded in a given period, used to gauge activity and liquidity.
18. Sector
A sector is a group of companies with similar business activities (e.g., technology, healthcare, energy).
19. Dividend Reinvestment Plan (DRIP)
A DRIP automatically uses dividends to buy more shares, compounding your returns.
20. Volatility Index (VIX)
The VIX is a measure of market volatility, sometimes called the “fear index.”
