BASIC INVESTMENT TYPES
─────────────────────────────────────────────────────────────────
STOCK
Definition: A share of ownership in a company. When you buy stock, you become a partial owner of that business.
Example: If you buy 10 shares of Apple stock, you own a tiny piece of Apple Inc. and can benefit from the company’s growth.
BOND
Definition: A loan you make to a company or government. They promise to pay you back with interest over time.
Example: You buy a $1,000 U.S. Treasury bond with 4% interest. The government pays you $40/year and returns your $1,000 after 10 years.
MUTUAL FUND
Definition: A pooled investment where many investors’ money is combined to buy a diversified collection of stocks, bonds, or other securities.
Example: Instead of picking individual stocks, you invest $1,000 in a mutual fund that owns 500 different companies.
ETF (EXCHANGE-TRADED FUND)
Definition: Similar to a mutual fund but trades like a stock throughout the day. Usually tracks an index with low fees.
Example: The SPY ETF tracks the S&P 500 index. You can buy or sell shares anytime during market hours, just like a stock.
INDEX FUND
Definition: A fund designed to match the performance of a specific market index by owning all (or most) of the securities in that index.
Example: A S&P 500 index fund owns shares of all 500 companies in the S&P 500, giving you instant diversification.
REAL ESTATE INVESTMENT TRUST (REIT)
Definition: A company that owns and operates income-producing real estate. Allows you to invest in real estate without buying property.
Example: You buy shares in a REIT that owns 50 apartment buildings across the country and receive dividend income from rent payments.
INVESTMENT ACCOUNTS
─────────────────────────────────────────────────────────────────
401(K)
Definition: An employer-sponsored retirement account where contributions are made pre-tax, reducing your current taxable income.
Example: You earn $60,000 and contribute $6,000 to your 401(k). You only pay taxes on $54,000 this year, saving about $1,320 in taxes.
IRA (INDIVIDUAL RETIREMENT ACCOUNT)
Definition: A personal retirement account you open yourself (not through employer) with tax advantages.
Example: You open a Roth IRA and contribute $7,000. The money grows tax-free, and you won’t pay taxes on withdrawals in retirement.
ROTH IRA
Definition: A retirement account where contributions are made with after-tax dollars, but withdrawals in retirement are completely tax-free.
Example: You contribute $7,000 after paying taxes on it. In 30 years it grows to $50,000, and you can withdraw all $50,000 tax-free.
TRADITIONAL IRA
Definition: A retirement account where contributions may be tax-deductible now, but you pay taxes on withdrawals in retirement.
Example: You contribute $7,000 and deduct it from this year’s taxes. In retirement, you’ll pay regular income tax when you withdraw.
BROKERAGE ACCOUNT
Definition: A taxable investment account with no restrictions on when you can withdraw money or how much you can contribute.
Example: You open a brokerage account at Fidelity with $5,000 and can buy/sell investments anytime without penalties.
CUSTODIAL ACCOUNT
Definition: An investment account an adult manages for a minor child until they reach legal age (18 or 21 depending on state).
Example: You open a custodial account for your daughter and invest $100/month. When she turns 18, the account transfers to her control.
STOCKS & EQUITY TERMS
─────────────────────────────────────────────────────────────────
SHARE
Definition: A single unit of ownership in a company’s stock. The basic unit you buy when purchasing stock.
Example: Tesla has 3.2 billion shares outstanding. When you buy 1 share, you own 1/3,200,000,000 of Tesla.
DIVIDEND
Definition: A payment made by a company to its shareholders, usually from profits. Not all companies pay dividends.
Example: Coca-Cola pays $1.84 per share annually. If you own 100 shares, you receive $184/year in dividend income.
STOCK SPLIT
Definition: When a company divides its existing shares into multiple shares to lower the stock price without changing total value.
Example: You own 10 shares at $100 each ($1,000 total). After a 2-for-1 split, you have 20 shares at $50 each (still $1,000).
MARKET CAPITALIZATION (MARKET CAP)
Definition: The total value of a company calculated by multiplying share price by total shares outstanding.
Example: Apple has 15.5 billion shares at $180 each. Market cap = 15.5B × $180 = $2.79 trillion.
BLUE CHIP STOCK
Definition: Stock in a large, well-established, financially stable company with a history of reliable performance.
Example: Companies like Microsoft, Johnson & Johnson, and Procter & Gamble are considered blue chip stocks.
PENNY STOCK
Definition: Low-priced stock (usually under $5) of small companies. Highly volatile and risky.
Example: A small biotech company trades at $0.50/share. It could jump to $2 or drop to $0.10—very unpredictable.
BONDS & FIXED INCOME
─────────────────────────────────────────────────────────────────
COUPON RATE
Definition: The interest rate a bond pays annually, expressed as a percentage of the bond’s face value.

MATURITY DATE
Definition: The date when a bond’s principal (original investment) is repaid to the bondholder.
Example: You buy a 10-year bond in 2025. The maturity date is 2035, when you get your principal back.
YIELD
Definition: The income return on an investment, expressed as a percentage. For bonds, it’s the annual interest divided by the current price.
Example: A bond pays $40/year and currently costs $800. Yield = $40/$800 = 5%.
TREASURY BOND
Definition: A long-term debt security issued by the U.S. government, considered one of the safest investments.
Example: You buy a 30-year Treasury bond. The U.S. government promises to pay interest every six months and return principal in 30 years.
CORPORATE BOND
Definition: A bond issued by a corporation to raise money. Riskier than government bonds but usually offers higher interest rates.
Example: Microsoft issues bonds to finance a new data center. You lend them money and receive interest payments.
BOND RATING
Definition: A grade assigned to bonds indicating creditworthiness and risk of default (AAA is highest, D is default).
Example: A bond rated AAA is very safe. A bond rated BB is more risky but pays higher interest to compensate.
PORTFOLIO
Definition: The complete collection of all your investments (stocks, bonds, funds, etc.) held in your accounts.
Example: Your portfolio includes $10,000 in stocks, $5,000 in bonds, and $3,000 in a money market fund = $18,000 total portfolio.

Example: A fund with 0.50% expense ratio charges $50/year for every $10,000 invested. Lower is better.
LOAD
Definition: A sales commission charged when buying or selling mutual fund shares. No-load funds have no commission.
Example: A fund with a 5% front-end load charges $250 on a $5,000 investment, so only $4,750 actually gets invested.
NET ASSET VALUE (NAV)
Definition: The per-share value of a mutual fund, calculated by dividing total fund assets minus liabilities by number of shares.
Example: A fund has $100 million in assets and 5 million shares. NAV = $100M ÷ 5M = $20 per share.

UNREALIZED GAIN/LOSS
Definition: Profit or loss on an investment you still own (haven’t sold yet). Also called ‘paper’ gain or loss.
Example: You bought stock for $100, now worth $150. You have a $50 unrealized gain. If you sell, it becomes a realized gain.
CORRELATION
Definition: How two investments move in relation to each other. Positive correlation = move together; negative = move opposite.

INVESTMENT STRATEGIES
─────────────────────────────────────────────────────────────────
DOLLAR-COST AVERAGING (DCA)

COMPOUND ANNUAL GROWTH RATE (CAGR)
Definition: The average yearly growth rate over a specific period, accounting for compounding.
