#### Course structure

This investments course begins by introducing fundamental concepts in investing. These include concepts such as the holding period return, arithmetic average return, geometric average return, etc. Then, we move on to the portfolio theory. In particular, we explain how to calculate portfolio return and risk. Afterward, we discuss how to form efficient portfolios. The final part of the course deals with the concept of market equilibrium. This is where we introduce asset pricing models such as the capital asset pricing model (CAPM) and the arbitrage pricing theory (APT).

#### Lessons

- Return calculations in 3 easy steps: We begin the course by teaching the basics of return calculations, covering concepts such as gross return, net return, and more.
- Real return vs nominal return: When making return calculations, it is important to take the rate of inflation into account as it creates a wedge between nominal returns and real returns.
- Holding period return: Investors often hold assets over a number of months/years. We teach how to make holding period return (HPR) calculations.
- Arithmetic average return: This is arguable the simplest investment statistic for assessing investment performance across multiple periods.
- Geometric average return: We explain the formula for this popular metric of investment performance and offer a calculator as well.
- Return volatility: It is important for investors to take into risk as well as return when making investment decisions. Return volatility is a popular risk measure that captures how volatile an asset’s returns are.
- Expected return: We introduce expected return as a forward-looking measure of investment performance, explain its formula, and provide a convenient calculator.
- The risk-free rate of return: We explain the concept of a risk-free asset and why yields on government securities are often used as estimates of the risk-free rate.
- Risk appetite: We offer a definition of risk appetite and distinguish it from risk capacity and risk tolerance.
- Risk aversion coefficient – Meaning and formula.
- Risk premium – What does it mean?
- Portfolio return – Calculator and formula.
- Portfolio risk – Calculator and formula.
- Efficient frontier – Efficient portfolios vs inefficient portfolios.

- Treynor ratio – Calculator, formula, and examples.
- Investments quiz – Test your learning of the material taught in this course.

If you are a total beginner to investing, we suggest you begin with the first lesson: basic return calculations. If you are comfortable performing simple return calculations, you can head straight to return volatility or expected return where we discuss investment risk and return in more detail. Or, if you are comfortable with investment basics, you can start from portfolio return where we begin to cover modern portfolio theory.
