market index, such as the ASX 200. By summing the returns for the company's shares and the market
index, the covariance and variance may be derived. The beta coefficient, which represents the
corporation's three-year beta, is calculated by dividing the covariance by the variance.
It is critical to remember that the accuracy of the calculated beta is affected by the quality of the
historical data and the time span of the research. It is also recommended to utilise reliable financial
software or seek expert guidance in order to acquire correct and up-to-date data for the
computations. The three-year beta reveals significant information regarding the company's
sensitivity to market movements. A beta greater than one indicates that the stock is expected to be
more volatile than the market, whilst a beta less than one indicates less volatility. Investors may use
the beta coefficient to estimate the level of risk associated with a stock and make sensible
investment decisions.
Finally, the CAPM provides an efficient approach for determining the expected return on an
investment based on its risk in relation to the market as a whole. The risk-free rate, beta, and market
return are all included while computing the CAPM. By properly determining the beta coefficient,
investors may evaluate the degree of risk associated with a certain investment and make better
educated selections.
Practical application - Calculation of Beta
A final requirement is to calculate the three-year Beta for a publicly listed company from those
companies listed on the ASX
BHP Group Limited is a resource firm that operates in Australia, Europe, China, Japan, India, South
Korea, the rest of Asia, North America, South America, and globally. The corporation operates in

To calculate three-year Beta, firstly I selected historical data of the companies and the frequency had
been changed to weekly to find it better as there is just a lot of noise using daily. The time period
already mentioned is three- year. So I selected three-year of the time period. The only thing that I
need onto the excel is adjusted closing price for BHP and AMZN. In order to calculate beta, the
important thing is to calculate weekly returns.
Returns BHP =Adjusted closing price BHP(B2) / Adjusted closing price BHP(B3) - 1
Returns AMZN= Adjusted closing price AMZN(C2) / Adjusted closing price AMZN(C3) - 1
