Curriculum

01

Risk and returns

Uncertainty, inflation, and price changes affect investment outcomes.

  1. 01Risk and ReturnInvestment risk and return describe uncertainty around possible outcomes and their gains or losses; higher potential returns do not guarantee better results.
  2. 02Real ReturnReal return adjusts investment performance for inflation and shows how purchasing power changes rather than only nominal value.
  3. 03VolatilityVolatility measures how returns vary around a reference value but does not capture every form of investment risk.

02

Investment building blocks

Stocks, bonds, and interest rates create different claims and risks.

  1. 04StocksStocks represent ownership in companies and may produce returns through distributions and price changes while exposing shareholders to losses.
  2. 05BondsBonds are debt instruments whose prices and yields depend on payment terms, credit risk, and market interest rates.
  3. 06Interest RatesInterest rates measure interest charged or earned over a stated period and affect borrowing, saving, and asset prices.

03

Building a portfolio

Diversification and asset allocation organize investments into a portfolio.

  1. 07PortfolioA portfolio combines investments and other financial positions whose weights, interactions, costs, and liquidity shape the overall outcome.
  2. 08DiversificationDiversification spreads investment risk across holdings but cannot prevent market-wide losses.
  3. 09Asset AllocationAsset allocation divides a portfolio among asset classes and shapes its expected risk and return.

04

Investing in practice

Funds, costs, and regular contributions affect how a plan is implemented.

  1. 10Index FundIndex funds track rule-based benchmarks, while costs and implementation can cause their returns to differ from the index.
  2. 11Exchange-Traded Fund (ETF)Exchange-traded funds pool investments into shares that trade on exchanges at market prices throughout the trading day.
  3. 12Expense RatioAn expense ratio measures recurring fund operating costs as a share of assets but does not include every cost an investor may bear.
  4. 13Dollar-Cost Averaging (DCA)Dollar-cost averaging invests equal amounts on a schedule and spreads purchases across market prices without removing the risk of loss.

How to use this path

Work through the lessons in order. Each chapter builds on the previous one: first define the risks and returns you are accepting, then understand the investments you can own, decide how they fit together, and finally examine practical ways to implement a plan.

This path explains principles rather than recommending a particular security or portfolio. Your appropriate choices depend on factors such as your goals, time horizon, ability to bear losses, need for accessible cash, taxes, and local rules.

Before you invest

Investing involves the possibility of loss. Money needed for near-term spending or emergencies may require a different approach from money intended for long-term goals. Before acting, separate the decision to invest from the decision about what to buy: define the goal, time horizon, and constraints first.

No lesson can make an investment safe or guarantee a return. Use the concepts in this path to ask better questions, compare trade-offs, and recognize when professional advice may be appropriate.
