Calculating the Required Rate of Return using Bloomberg

0 comments

Calculate the required rate of return for your stock. To do this, you will use the Capital Asset Pricing Model. You will need several pieces of publicly available information – risk free rate, company’s beta, and the rate of return on a selected stock index.To calculate the required rate of return for your assigned company, follow the instructions below.

  • Calculate beta for your company. This process was detailed in class. You can refer back to the posted spreadsheets and lectures.
    • Open Yahoo Finance and put in your company’s ticker. Click on Historical Data and get 3 months of stock prices. Download and keep the date and adjusted close price in the Excel file. Go back and do the same thing for the market (use the S&P 500, which has a ticker of ^GSPC). Insert the market adjusted close prices into the same Excel file to the left of your company’s stock prices.
    • Next, calculate the daily returns for both your company and the market (create two additional columns for this).
    • Highlight these returns and insert a scatter plot into Excel.
    • Appropriately label the graph (title, x and y axes).
    • Then put in the Characteristic line: Add Chart Element, Trendline – and make sure that “display equation” is checked. You should now have your estimate of beta. Use this for the remainder of the project.
