What Is Beta?

A stock that swings more than the market over time has a beta greater than 1.0. If a stock moves less than the market, the stock’s beta is less than 1.0. High-beta stocks tend to be riskier but provide the potential for higher returns. Low-beta stocks pose less risk but typically yield lower returns.

What is the covariance of TSLA and SPY?

Based on recent five-year data, TSLA and SPY have a covariance of 0.032, and the variance of SPY is 0.015.

How to calculate beta of a security?

To calculate the beta of a security, the covariance between the return of the security and the return of the market must be known, as well as the variance of the market returns. Covariance measures how two stocks move together. A positive covariance means the stocks tend to move together when their prices go up or down.

Why are low beta stocks important?

Low-beta stocks pose less risk but typically yield lower returns. As a result, beta is often used as a risk-reward measure, meaning it helps investors determine how much risk they are willing to take to achieve the return for taking on that risk. A stock’s price variability is important to consider when assessing risk.

What is the beta of a stock?

Beta is a measure used in fundamental analysis to determine the volatility of an asset or portfolio in relation to the overall market. The overall market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market.

What is the difference between positive and negative covariance?

A positive covariance means the stocks tend to move together when their prices go up or down. A negative covariance means the stocks move opposite of each other. Variance, on the other hand, refers to how far a stock moves relative to its mean.

What is variance in stocks?

Variance, on the other hand, refers to how far a stock moves relative to its mean. For example, variance is used in measuring the volatility of an individual stock’s price over time. Covariance is used to measure the correlation in price moves of two different stocks.

What is beta in stock market?

Learn more… Beta is the volatility or risk of a particular stock relative to the volatility of the entire stock market. Beta is an indicator of how risky a particular stock is, and it is used to evaluate its expected rate of return.

What does it mean when the beta is negative?

Usually the rates of return are figured over several months. Either or both of these values may be negative, meaning that investing in the stock or the market (index) as a whole would mean a loss during the period. If only one of the two rates is negative, the beta will be negative.

What does a beta of 1 mean?

A beta of less than 1 means that the stock is less volatile than the market as a whole, while a beta greater than 1 means the stock is more volatile than the market as a whole. The beta value can be less than zero, meaning either that the stock is losing money while the market as a whole is gaining (more likely) or that the stock is gaining while the market as a whole is losing money (less likely).

Divide the first difference above by the second difference above. This fraction is the beta figure, typically expressed as a decimal value. In the example above, the beta would be 5 divided by 6, or 0.833.

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

How to calculate covariance?

To calculate the covariance Calculate The Covariance Covariance is a statistical measure used to find the relationship between two assets and is calculated as the standard deviation of the return of the two assets multiplied by its correlation. If it gives a positive number then the assets are said to have positive covariance i.e. when the returns of one asset goes up, the return of second assets also goes up and vice versa for negative covariance. read more, we must know the return of the stock and also the return of the market, which is taken as a benchmark value. We must also know the variance of the market return.

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.

Why do analysts use the beta coefficient?

Analysts examine the Beta Coefficient, or Beta of stock, because the Beta measures risk and volatility.

One approach is to obtain a comparable levered beta from an industry average or from a comparable company (or companies) that best mimics the current business of the private company, unlever this beta, and then find the levered beta for the private company using the company’s target debt-to-equity ratio. Alternatively, one can find the beta of the company’s earnings and use it as a proxy for the company after appropriate adjustments are made.

Why is the beta of a private company higher than the average levered beta?

In this example, the beta of the illustrative private company is higher than the average levered beta due to a higher target debt-to-equity ratio.

Why is beta important?

Beta is an important concept for the analysis of hedge funds. It can show the relationship between a hedge fund’s returns and the market return. Beta can show how much risk the fund is taking in certain asset classes and can be used to measure against other benchmarks, such as fixed income or even hedge fund indexes.

How to calculate beta?

The beta coefficient is calculated by dividing the covariance of the stock return versus the market return by the variance of the market. Beta is used in the calculation of the capital asset pricing model (CAPM). This model calculates the required return for an asset versus its risk. The required return is calculated by taking the risk-free rate plus the risk premium. The risk premium is found by taking the market return minus the risk-free rate and multiplying it by the beta.

Why is CAPM risky?

Risks arise because the market return may not meet expectations, the risk-free rate may go up or down and the asset’s beta may change.

What is CAPM in investing?

What is risk premium?

The market risk premium is the expected return of the market minus the risk-free rate : r m – r f. The market risk premium represents the return above the risk-free rate that investors require to put money into a risky asset, such as a mutual fund. Investors require compensation for taking on risk, because they might lose their money. If the risk-free rate is 0.4 percent annualized, and the expected market return as represented by the S&P 500 index over the next quarter year is 5 percent, the market risk premium is (5 percent – (0.4 percent annual/4 quarters per year)), or 4.9 percent.
