Asset Allocation
Asset allocation divides a portfolio among asset classes and shapes its expected risk and return.Bonds
Bonds are debt instruments whose prices and yields depend on payment terms, credit risk, and market interest rates.Compound Interest
Compound interest earns interest on previously credited interest, allowing time and reinvestment to amplify long-term growth.Consumer Price Index (CPI)
The Consumer Price Index measures changes in a weighted basket of prices and produces an inflation rate for a reference population.Dollar-Cost Averaging (DCA)
Dollar-cost averaging invests equal amounts on a schedule and spreads purchases across market prices without removing the risk of loss.Diversification
Diversification spreads investment risk across holdings but cannot prevent market-wide losses.Exchange-Traded Fund (ETF)
Exchange-traded funds pool investments into shares that trade on exchanges at market prices throughout the trading day.Expense Ratio
An expense ratio measures recurring fund operating costs as a share of assets but does not include every cost an investor may bear.Index Fund
Index funds track rule-based benchmarks, while costs and implementation can cause their returns to differ from the index.Inflation
A broad rise in prices that reduces purchasing power over time.Interest Rates
Interest rates measure interest charged or earned over a stated period and affect borrowing, saving, and asset prices.Money
Money is widely accepted for payments, used to state prices and debts, and held to move purchasing power through time.Portfolio
A portfolio combines investments and other financial positions whose weights, interactions, costs, and liquidity shape the overall outcome.Purchasing power
The amount of goods and services that one unit of money can buy.Real Return
Real return adjusts investment performance for inflation and shows how purchasing power changes rather than only nominal value.Risk and Return
Investment risk and return describe uncertainty around possible outcomes and their gains or losses; higher potential returns do not guarantee better results.Stocks
Stocks represent ownership in companies and may produce returns through distributions and price changes while exposing shareholders to losses.Volatility
Volatility measures how returns vary around a reference value but does not capture every form of investment risk.
