# What is Beta in Stock and Finance?

## Where is beta used

CAPM (Capital Asset Price Model) uses beta. CAPM is a model that shows the relationship between stock returns and systematic risk. It calculates the expected returns using capital costs and risks. It gives the investor an estimate of the risk that the stock may pose to their portfolio.

## How do you calculate beta?

Beta coefficients are used to measure volatility relative to market risk. It is the slope of the line calculated by a regression of data points. These data points compare the returns of individual stocks with those of the entire market.

Beta can be represented by:

Beta coefficient (b), = Covariance, Re, Rm/ Variance (Rm).

This equation is:

Re= The return on an individual stock

Rm = The return on the total market

Covariance = How changes in stock returns relate to market returns

Variance = The spread of market data points from their average value

## What is beta in stocks and what does it mean?

It is a measure of the stock's expected changes relative to market movements. Beta coefficient greater than 1 indicates that the stock is more volatile relative to the market. Beta less than 1 indicates lower volatility than the market. It is an integral part of CAPM which calculates the cost for equity funding. When making stock selections, beta is only of limited value. Beta is a better indicator for short-term than long-term risks.

## What is beta in finance?

High beta companies can offer high returns, but also have high risk.

b 1>0 -- Less volatile than market

b =0 – Stock that is not correlated with the market. Beta value for stocks without associated risks is 0. You can find examples of fixed deposits, government bonds, and cash.

b 0 = The stock is ininversely proportional the market. Gold is an example of such a stock.

b =1: The stock is closely related to the market, and has the same volatility like the market

b >1: The stock is more volatile that the market
