How to Calculate CAPM Alpha in Excel
Setting Up Your Excel Worksheet
To begin calculating CAPM alpha in Excel, first set up your spreadsheet with necessary assumptions clearly placed at the top. This setup allows easy reference and ensures calculations using fixed variables are easier to manage.
Understanding the CAPM Alpha Formula
The Capital Asset Pricing Model (CAPM) alpha formula is fundamental and calculates expected return based on risk and market variables. The core formula in its Excel version is = $C$3 + (C9 * ($C$4 - $C$3)), where $C$3 is the risk-free rate, C9 is the beta coefficient of your asset, and $C$4 represents the expected market return. Utilize the $ signs to lock cells for consistent calculations across multiple assets.
Performing the Calculation
In your Excel worksheet, apply the formula = $C$3 + (C9 * ($C$4 - $C$3)) starting from the row that corresponds to your first asset. Remember, the risk-free rate ($C$3) and the expected market return ($C$4) should remain fixed, ensuring accurate replication when dragged across other asset rows.
Comparing Multiple Assets
For batch processing of multiple assets, drag the formula across other cells in the row. This approach leverages Excel's ability to handle repetitive calculations efficiently, providing a quick means to compare expected returns across different investment opportunities.
Example: Real-World Application
For instance, in an analysis involving companies like Tesla and General Motors, CAPM alpha calculations could yield results such as 4.36% for Tesla and 10.10% for GM respectively. These results allow investors to gauge the expected returns adjusted for risk and relative to market performance.
How to Calculate CAPM Alpha in Excel
To compute the Capital Asset Pricing Model (CAPM) alpha in Excel, use the tailored formula: =$C$3+(C9*($C$4-$C$3)). This formula helps determine the expected return based on the risk-free rate, beta of the asset, and the market risk premium.
Setting Up Your Excel Sheet
Start by organizing your Excel workspace. Input the risk-free rate in cell C$3, the market risk premium in cell $C$4, and the beta of each asset in column C9. This arrangement allows for consistent references when expanding the formula to additional assets.
Implementing the CAPM Alpha Formula
Enter the formula =$C$3+(C9*($C$4-$C$3)) into the cell corresponding to your first asset. This incorporates the static references (due to the $ signs) to the cells containing the risk-free rate and market premium, which simplifies updates as these values change. The part of the formula involving asset beta (C9) will adjust as you copy the formula across other cells for different assets.
Copying the Formula for Multiple Assets
With the initial formula set up in the Excel cell, you can now copy this formula to adjacent cells. This method proves efficient for portfolios with multiple assets, allowing quick calculations of expected returns enhancing productivity in portfolio management.
Practical Example
For instance, applying the CAPM alpha formula for calculating Tesla’s expected return might yield a result of 4.36%, indicating Tesla’s performance above the risk-adjusted benchmark. Similarly, for General Motors, the expected return might be calculated as 10.10%.
Conclusion
Utilizing the CAPM in Excel makes it feasible to evaluate the risk-return profile of investments quickly. A correctly set up model supports not only individual asset evaluation but also a comprehensive view of portfolio performance against market expectations.

Examples of Calculating CAPM Alpha in Excel
Example 1: Basic Alpha Calculation
To calculate the CAPM alpha, input historical stock returns and market returns into Excel. Assume an expected market return of 10%, a risk-free rate of 3%, and beta of the stock as 1.2. Use the formula:Alpha = Stock Return - (Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)).For a stock return of 14%, alpha would be calculated as 14% - (3% + 1.2 * (10% - 3%)) = 1.6%.
Example 2: Portfolio Alpha
To calculate alpha for a portfolio, sum the products of the alphas and weights of individual assets. If you have two stocks with alphas of 1.6% and 2.0%, and weights of 50% each, the portfolio alpha is:Portfolio Alpha = 0.5 * 1.6% + 0.5 * 2.0% = 1.8%.
Example 3: Comparing Alpha Across Different Periods
Analyze alpha stability by calculating it across multiple periods. Use the same CAPM formula for each period. If in Year 1 alpha is 1.6%, and in Year 2 it is 1.9%, enter these into Excel to discern trends or patterns in performance relative to risks assumed. This helps in assessing the consistency of the investment strategy.
Example 4: Adjusted Alpha with Transaction Costs
Incorporate transaction costs into the alpha calculation to reflect net performance. If transaction costs average 0.5% per period, adjust the basic alpha calculation by deducting these costs:Adjusted Alpha = Basic Alpha - Transaction Costs. For a basic alpha of 1.6%, the adjusted alpha would be 1.1%.
Example 5: Using Excel's Regression Tool for Alpha
Utilize Excel's regression tool under Data Analysis for a more automated calculation. Set stock returns as the dependent variable and market excess returns (market return minus risk-free rate) as the independent variable. The intercept of the regression output is the alpha. This method considers all data points for a more fine-tuned analysis.
