What is the difference between beta coefficient and variance of return?
In the Beta Coefficient, the two numbers are the market return and the stock return. You can learn how to calculate covariance here. In portfolio management theory, the Variance of Return is a measure of an individual stock’s risk by itself. To explain, all the non-market risks assets with the stock.
What is the expected return on beta of stock a?
Stock A has a beta of .68 and an expected return of 8.1 percent. Stock B has a beta of 1.42 and an expected return of 13.9 percent. Stock C has beta of 1.23 and an expected return of 12.4 percent.
How do you interpret the beta coefficient of a stock?
A company with a higher beta has greater risk and also greater expected returns. The beta coefficient can be interpreted as follows: β =1 exactly as volatile as the market. β >1 more volatile than the market. β <1>0 less volatile than the market. β =0 uncorrelated to the market. β <0 negatively correlated to the market.
How do you calculate beta and covariance?
Covariance is used to measure the correlation in price moves of two different stocks. The formula for calculating beta is the covariance of the return of an asset with the return of the benchmark, divided by the variance of the return of the benchmark over a certain period.
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.
How to calculate beta?
Beta could be calculated by first dividing the security's standard deviation of returns by the benchmark's standard deviation of returns. The resulting value is multiplied by the correlation of the security's returns and the benchmark's returns.
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 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 the difference between high and low 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. As a result, beta is often used as ...
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.
What does beta mean in stocks?
Beta can give you an estimate of the stock’s risk and some idea of market volatility. Ideally, the Beta will tell you the difference between a stock’s risk and the risk of an entire index market.
What is covariance in portfolio management?
To clarify, Covariance is a measurement of the directional relationship between two numbers. In the Beta Coefficient, the two numbers are the market return and the stock return. You can learn how to calculate covariance here. In portfolio management theory, the Variance of Return is a measure of an individual stock’s risk by itself.
What is the beta coefficient?
Generally, analysts regard the Beta Coefficient as a measure of systematic or “general market” risk. Analysts often use the mathematical symbol β to represent the Beta in calculations. To explain, systematic is the level of risk or volatility of equity in the entire market or index.
Why do analysts use the beta coefficient?
Analysts examine the Beta Coefficient, or Beta of stock, because the Beta measures risk and volatility. Specifically, the Beta can give you an estimate of the stock’s risk and some idea of market volatility. Ideally, the Beta will tell you the difference between a stock’s risk and the risk of an entire index market.
Why is beta a limited tool?
Hence, the Beta is a limited tool because it only measures some risks associated with individual stocks or indexes. However, a rough estimate of risk is better than no estimate of risk.
What does a value of 5 mean?

What does a beta mean in stocks?
Beta, which has a value of 1, indicates that it exactly moves in accordance with the market value. A higher beta indicates that the stock is riskier, and a lower beta indicates that the stock is less volatile as compared to the market. Mostly Betas generally fall between the values of range 1.0 to 2.0.
What is beta in stock market?
Beta is a measure of the volatility of the stock as compared to the overall stock market. Overall Stock Market Stock Market works on the basic principle of matching supply and demand through an auction process where investors are willing to pay a certain amount for an asset, and they are willing to sell off something they have at a specific price.

Advantages of using Beta Coefficient. One of the most popular uses of Beta is to estimate the cost of equity (Re) in valuation models. The CAPM estimates an asset’s Beta based on a single factor, which is the systematic risk of the market.
What are the drawbacks of beta?
The largest drawback of using Beta is that it relies solely on past returns and does not account for new information that may impact returns in the future. Furthermore, as more return data is gathered over time, the measure of Beta changes, and subsequently, so does the cost of equity.

The Bottom Line
- Betas vary across companies and sectors. Many utility stocks, for example, have a beta of less than 1. Conversely, many high-tech stocks on the Nasdaq have a beta greater than 1, offering the possibility of a higher rate of return, but also posing more risk. It's important that investors distinguish between short-term risks (where beta and price volatility are useful) and long-term ri…
