General Investing Concepts
- Asset Allocation: The strategy of distributing investments across asset classes — stocks, bonds, and cash — to balance risk and return based on your goals.
- Diversification: Spreading investments across many assets, sectors, or geographies to reduce the impact of any single loss on your overall portfolio.
- Risk Tolerance: Your ability and willingness to endure investment losses. Higher risk tolerance generally supports a larger allocation to stocks.
- Liquidity: How easily and quickly an asset can be converted to cash at or near its current market value. Stocks are highly liquid; real estate is not.
- Time Horizon: The length of time you plan to hold investments before needing the funds. Longer horizons can typically absorb more short-term volatility.
- Compound Interest: Earning returns on both your original investment and previously earned returns. A 7% annual return doubles an investment roughly every 10 years.
Stock Market Terms
- Stock (Share / Equity): A unit of ownership in a publicly traded company. Stockholders may benefit from price appreciation and dividend payments.
- Dividend: A cash payment distributed by a company to its shareholders, typically from earnings. Expressed as dividend yield (annual dividend ÷ stock price).
- Market Capitalization: The total value of a company's outstanding shares (share price × shares outstanding). Companies are classified as small-cap (under $2B), mid-cap ($2B–$10B), or large-cap (over $10B).
- Bull Market: A period of rising stock prices — generally defined as a 20% or more gain from a recent low. Associated with strong economic growth and investor optimism.
- Bear Market: A period of declining stock prices — generally defined as a 20% or more decline from a recent high. Often coincides with economic slowdowns or recessions.
- Index: A benchmark tracking the performance of a group of stocks. Common examples include the S&P 500 (500 large U.S. companies) and the Dow Jones Industrial Average (30 blue-chip companies).
Investment Vehicles and Strategies
| Term | Definition |
|---|---|
| Index Fund | A mutual fund that tracks a market index — low cost, broad diversification, passive management |
| ETF (Exchange-Traded Fund) | A basket of stocks or bonds that trades on an exchange like a single stock — often lower cost than mutual funds |
| Mutual Fund | A pooled investment managed by a professional fund manager — actively or passively managed |
| Growth Investing | Targeting companies with rapidly expanding revenues, often with higher P/E ratios and no dividends |
| Value Investing | Buying stocks that appear undervalued relative to their fundamentals — low P/E or low P/B ratios |
| Dollar-Cost Averaging | Investing a fixed dollar amount at regular intervals regardless of market price, smoothing entry costs |
| Rebalancing | Periodically adjusting your portfolio back to target allocations after market movements shift the balance |
Bond and Fixed Income Terms
- Bond: A debt instrument — you lend money to a government or corporation, which pays you regular coupon payments and returns your principal at maturity.
- Yield: The income return on a bond, expressed as a percentage of its current price. Yield and bond price move in opposite directions.
- Coupon Rate: The fixed annual interest rate paid on a bond's face value. A $1,000 bond with a 5% coupon pays $50 per year.
- Maturity: The date on which the bond issuer repays the principal. Terms range from short-term (under 2 years) to long-term (10–30 years).
- Duration: A measure of a bond's sensitivity to interest rate changes. Longer duration means greater price movement when rates shift.
- Credit Rating: An assessment of a bond issuer's ability to repay debt. Investment-grade bonds (BBB– and above) carry lower default risk than junk bonds (BB+ and below).
Key Financial Metrics
- P/E Ratio (Price-to-Earnings): Stock price divided by earnings per share. A higher P/E can indicate growth expectations or overvaluation — compare within the same industry.
- EPS (Earnings Per Share): A company's net income divided by shares outstanding. Rising EPS generally signals improving profitability.
- ROI (Return on Investment): The profit or loss from an investment relative to its cost — expressed as a percentage. Formula: (Gain − Cost) ÷ Cost × 100.
- Capital Gains: Profit earned from selling an investment above its purchase price. Short-term gains (held under 1 year) are taxed as ordinary income; long-term gains (held over 1 year) receive lower tax rates.
- Short Selling: Borrowing and selling shares you do not own, hoping to repurchase them at a lower price. High-risk strategy with theoretically unlimited loss potential.
