The efficient frontier is determined through the process of portfolio optimization, which involves analyzing the risk and return characteristics of different investment portfolios. The efficient frontier represents the set of portfolios that offer the highest expected return for a given level of risk or the lowest level of risk for a given expected return.
To determine the efficient frontier, the following steps are typically followed:
1. Identify the available investment assets: This involves considering a range of investment options such as stocks, bonds, mutual funds, and other financial instruments.
2. Estimate the expected returns and risks of individual assets: Historical data, financial analysis, and market research are used to estimate the expected returns and risks associated with each investment asset.
3. Construct a set of hypothetical portfolios: Different combinations of investment assets are created to form a set of hypothetical portfolios. Each portfolio has a unique allocation of assets, which determines the expected return and risk of the portfolio.
4. Calculate the expected return and risk of each portfolio: The expected return of a portfolio is calculated by weighing the expected returns of individual assets based on their allocation in the portfolio. The risk of a portfolio is determined by considering the covariance or correlation between the returns of different assets in the portfolio.
5. Plot the portfolios on a risk-return graph: The expected return of each portfolio is plotted on the y-axis, and the risk (standard deviation or variance) of each portfolio is plotted on the x-axis. This creates a scatter plot of portfolios.
6. Identify the efficient frontier: The efficient frontier is determined by identifying the set of portfolios that offer the highest expected return for a given level of risk or the lowest level of risk for a given expected return. This is achieved by drawing a curve that connects the portfolios with the highest risk-adjusted returns.
7. Select an optimal portfolio: Investors can choose a portfolio from the efficient frontier based on their risk tolerance and return objectives. The optimal portfolio is the one that provides the best trade-off between risk and return according to the investor's preferences.
It is important to note that the efficient frontier is not a fixed concept and can change over time due to changes in asset prices, expected returns, and risk levels. Therefore, regular portfolio monitoring and adjustments are necessary to maintain an optimal portfolio allocation.
