  • The investment opportunity curve illustrates the trade-off between risk and return for different portfolios, highlighting the efficient set of investment choices.
  • Portfolios on the efficient frontier are optimized to provide the highest possible return for a given level of risk.
  • Understanding the investment opportunity curve helps investors make informed decisions about portfolio diversification and asset allocation.

What is the investment opportunity curve?

Copy link to section

The investment opportunity curve is a graphical representation of the different combinations of risk and return that can be achieved by varying the mix of assets in an investment portfolio. It is derived from the efficient frontier, which represents the optimal portfolios that offer the maximum expected return for a given level of risk. Portfolios that lie below the efficient frontier are suboptimal, as they provide lower returns for the same level of risk compared to those on the frontier.

Example

Copy link to section

Consider an investor choosing between different combinations of stocks and bonds. By varying the proportion of each asset class, the investor can create a range of portfolios with different expected returns and risks. The investment opportunity curve will display the optimal portfolios that maximize returns for each level of risk, helping the investor select the best mix of assets.

Key components of the investment opportunity curve

Expected return

Copy link to section

Expected return is the anticipated profit or loss from an investment portfolio, usually expressed as a percentage. It is calculated based on the historical performance of the assets and their expected future performance.

Risk (standard deviation)

Copy link to section

Risk in the context of the investment opportunity curve is typically measured by the standard deviation of portfolio returns. Standard deviation quantifies the variability or volatility of returns, indicating the degree of uncertainty associated with the investment.

Efficient frontier

Copy link to section

The efficient frontier is a key concept in modern portfolio theory. It represents the set of optimal portfolios that offer the highest expected return for a given level of risk. Portfolios on the efficient frontier are considered efficient because no other portfolio offers a better risk-return trade-off.

Diversification

Diversification is the practice of spreading investments across different assets to reduce risk. The investment opportunity curve demonstrates the benefits of diversification, showing how combining different assets can create portfolios with lower risk for a given return level.
