What is beta and how do you find it?
To calculate beta, start by finding the risk-free rate, the stock's rate of return, and the market's rate of return all expressed as percentages. Then, subtract the risk-free rate from the stock's rate of return. Next, subtract the risk-free rate from the market's rate of return.

How to calculate beta of a stock?
Here is a straightforward formula for calculating the Beta Coefficient of a Stock: 1 Obtain the stock’s historical share price data. 2 Obtain historical values of a market index, e.g., S&P 500. 3 Convert the share price values into daily return values using the following formula: return = (closing share price − opening share price)/opening share price. 4 Convert historical stock market index values in a similar way. 5 Align the share return data with index return such that there is a 1-on-1 correspondence between them. For share price return, there should be a corresponding index return. 6 Using the SLOPE function in a financial calculator to find the slope between both arrays of data and the resultant figure is Beta.

How to interpret beta?
Know how to interpret beta. Beta is the risk, relative to the stock market as a whole, an investor assumes by owning a particular stock. That's why you need to compare the returns of a single stock against the returns of an index. The index is the benchmark against which the stock is judged. The risk of an index is fixed at 1. A beta of lower than 1 means that the stock is less risky than the index to which it's being compared. A beta of higher than 1 means the stock is more risky than the index to which it's being compared.
What does it mean when the beta is lower than 1?
The risk of an index is fixed at 1. A beta of lower than 1 means that the stock is less risky than the index to which it's being compared. A beta of higher than 1 means the stock is more risky than the index to which it's being compared.

How to calculate the return of a stock?
Begin calculating returns for the stock market index. 1 Since return is a calculation over time, you won't put anything in your first cell; leave it blank. You need at least two data points to calculate returns, which is why you'll start on the second cell of your index-returns column. 2 What you're doing is subtracting the more recent value from the older value and then dividing the result by the older value. This just gives you the percent of loss or gain for that period. 3 Your equation for the returns column might look something like this: = (B4-B3)/B3
