The formula for the CAPM is expressed as:R_STOCK= R_RF+ ( R_M- R_RF)

Where:

R_STOCK= the Return of the individual security

R_RF= the Risk-free rate of return (usually the going rate on short-term Treasury Bills)

= the beta coefficient, a measure of riskiness of the stock relative to the riskiness of the market. A beta of 1 means that the stock has the same level of risk as the overall market. A beta of less than 1 means less risk than the overall market, and more than 1 means it is more risky.

R_M= the Return of the market

For example, using this model we can compute the required return for IBM stock if we know a few things. We must know:

1. The going rate on Short-term Treasury Bills. This approximates the Risk-free rate.
2. The rate of return for the S&P 500. This is traditionally used to approximate the Return of the market.
3. The beta coefficient of the stock. This can be computed using the historical rates of return for the individual stock and the historical rates of return for the market using a regression analysis. Or, you can look it up on YahooFinance.com!

Let's assume that the Risk-free rate is 3%, the Return of the S&P is 10%, and the Beta for IBM is 0.9. Here's our calculation:

R_IBM= 3% + 0.9(10% -3%) = 9%

This means that IBM must have a 9% return in order to compensate investors for putting their money in IBM stock instead of elsewhere.

Directions:

1. Select a publicly-traded company. - Johnson & Johnson
2. Go tofinance.yahoo.comEnter the company's stock symbol in the "Get Quotes" box. If you do not know the stock symbol, you can enter the company's name in the search tool. - https://finance.yahoo.com/quote/NKLA?p=NKLA&.tsrc=fin-srch
3. Search for the company'sBeta coefficient on the Summary page. Make a note of this number.
4. Next, go to the Key Statistics page. The link is located in the left-hand column. Once on the Key Statistics page look for the"Trading Information"Here you will find the 52-week change for the stock and for the S&P 500. Write these two numbers down.
5. Next, go toTreasury.govand search for information on US Treasury Bills.There should be 3-month, 6-month, 2-year, etc. These are found toward the bottom of the home page in an area called Data Center.Select the 6-month rate, and make a note of this number.
6. Using the information above (the stock's Beta, the rate on the 6-month Treasury, and the average 52-week return for the S&P 500) compute the required rate of return for your stock. In other words,plug these numbers into the CAPM model.

Requirements for your Main thread post:

1. Title your post with the name of your company so that other students will not duplicate your work.
2. Compare the required rate of return that you just computed with the 52-week change for the security. Show us your work!
3. What do you notice? How does the computed CAPM expected return compare with the actual 52-week return?
4. In your opinion, is this stock a good investment? Please explain your answer.
