• Explain different types of financial risk, such as market risk, credit risk, and liquidity risk.
• Calculate and interpret statistical measures of risk, including variance, standard deviation, and beta.
• Apply risk and return concepts in portfolio management and investment decision-making.

Materials:

• Whiteboard or projector
• Markers or pens
• Slides or presentation materials
• Financial calculators or spreadsheet software
• Handouts with formulas and practice problems

Lesson Outline:

I. Introduction (10 minutes)

• Begin by discussing the basic concepts of risk and return in finance.
• Engage the class with a discussion on why investors demand a return for taking on risk.
• Explain the fundamental trade-off between risk and return.

II. Measuring Investment Returns (30 minutes)

• Define and explain the following measures of investment return:
  • Holding Period Return (HPR): The total return received from holding an asset or portfolio of assets over a period of time. $HPR = \frac{P\_1 - P\_0 + D\_1}{P\_0}$ Where:
    • $P\_1$ = Price at the end of the period
    • $P\_0$ = Price at the beginning of the period
    • $D\_1$ = Cash distributions (dividends) during the period
  • Arithmetic Average Return: The simple average of a series of returns. $\text{Arithmetic Average Return} = \frac{\sum\_{i=1}^{n} R\_i}{n}$ Where:
    • $R\_i$ = Return in period i
    • n = Number of periods
  • Geometric Average Return: The average return of an investment over time. \text{Geometric Average Return} = \left\[\prod\_{i=1}^{n} (1 + R\_i)\right\]^{\frac{1}{n}} - 1 Where:
    • $R\_i$ = Return in period i
    • n = Number of periods
• Illustrate each calculation with examples.
• Discuss the differences between arithmetic and geometric average returns and when to use each.

III. Types of Financial Risk (20 minutes)

• Explain the various types of financial risk:
  • Market Risk (Systematic Risk): The risk of losses in positions due to factors that affect the broader market.
  • Credit Risk: The risk that a borrower will default on any type of debt by failing to make required payments.
  • Liquidity Risk: The risk that a given security or asset cannot be traded quickly enough in the market to prevent a loss.
  • Operational Risk: The risk of losses resulting from inadequate or failed internal processes, people, and systems, or from external events.
• Provide real-world examples of each type of risk.
• Discuss how these risks can impact investment portfolios.

IV. Measuring Risk (30 minutes)

• Introduce statistical measures of risk:
  • Variance: A measurement of the degree of variability in a data set. $\text{Variance} = \frac{\sum\_{i=1}^{n} (R\_i - \bar{R})^2}{n-1}$ Where:
    • $R\_i$ = Return in period i
    • $\bar{R}$ = Average return
    • n = Number of periods
  • Standard Deviation: A statistical measure of the amount of dispersion of a set of values. $\text{Standard Deviation} = \sqrt{\text{Variance}}$
  • Beta: A measure of a stock's volatility in relation to the market. $\beta = \frac{\text{Covariance of asset with market}}{\text{Variance of market}} = \frac{\text{Cov(Ri, Rm)}}{\text{Var(Rm)}}$
• Demonstrate how to calculate variance and standard deviation using sample data.
• Explain what beta measures and how it is interpreted.
• 
• Discuss the limitations of these measures.

V. Risk and Return in Portfolio Management (20 minutes)

• Discuss how risk and return are considered in portfolio management.
• Explain the concept of diversification and how it can reduce risk.
• Introduce the Capital Asset Pricing Model (CAPM) as a tool for evaluating risk-adjusted returns.
  • $R\_a = R\_{rf} + \beta\_a (R\_m - R\_{rf})$ Where:
    • $R\_a$ = Expected return on the asset
    • $R\_{rf}$ = Risk-free rate of return
    • $\beta\_a$ = Beta of the asset
    • $R\_m$ = Expected market return
• Discuss the importance of asset allocation in managing risk and return.

VI. Conclusion (10 minutes)

• Recap the key concepts covered in the lesson.
• Address any remaining questions.
• Provide additional resources for further study.

Assessment:

• Problem sets involving calculations of return and risk measures.
• Case studies analyzing risk and return in real-world investment scenarios.
