# What is “beta” for an investment or a portfolio, and how do I use it?

A security’s beta is calculated by dividing the product of the covariance of the security’s returns and the market’s returns by the variance of the market’s returns over a specified period. The beta calculation is used **to help investors understand whether a stock moves in the same direction as the rest of the market**.

## How do you explain beta of a portfolio?

The beta of a portfolio is **the weighted sum of the individual asset betas, According to the proportions of the investments in the portfolio**. E.g., if 50% of the money is in stock A with a beta of 2.00, and 50% of the money is in stock B with a beta of 1.00,the portfolio beta is 1.50.

## What does beta tell you in investing?

Beta is **a way of measuring a stock’s volatility compared with the overall market’s volatility**. The market as a whole has a beta of 1. Stocks with a value greater than 1 are more volatile than the market (meaning they will generally go up more than the market goes up, and go down more than the market goes down).

## How do you use beta for stocks?

Key Takeaways

**A beta greater than 1 indicates a stock’s price swings more wildly (i.e., more volatile) than the overall market**. A beta of less than 1 indicates that a stock’s price is less volatile than the overall market. A beta of 1 indicates the stock moves identically to the overall market.

## How do you read a stock beta?

**Key Takeaways**

- Beta is a concept that measures the expected move in a stock relative to movements in the overall market.
- A beta greater than 1.0 suggests that the stock is more volatile than the broader market, and a beta less than 1.0 indicates a stock with lower volatility.

## How do I make a beta portfolio?

**Portfolio Beta formula**

- Add up the value (number of shares x share price) of each stock you own and your entire portfolio.
- Based on these values, determine how much you have of each stock as a percentage of the overall portfolio.
- Take the percentage figures and multiply them with each stock’s beta value.

## What is the beta for a portfolio with an expected return of 12.5 %?

What is the beta for a portfolio with an expected return of 12.5%? Since rf = 5% and E(rM) = 10%, from the CAPM we know that 12.5% = 5% + beta(10% – 5%), and therefore **beta = 1.5**.

## What is considered a high beta?

What are high-beta stocks? A high-beta stock, quite simply, is **a stock that has been much more volatile than the index it’s being measured against**. A stock with a beta above 2 — meaning that the stock will typically move twice as much as the market does — is generally considered a high-beta stock.

## What stock has the highest beta?

## Is beta a good measure of risk?

The underlying reason that **beta is ineffective as an indicator of risk**, or the potential for long-term loss of capital, is that beta is simply a measure of share price volatility. The true risk associated with a company is a result of its business fundamentals.

## What does a stock beta of 1.5 mean?

## Is beta a better measure of risk than standard deviation?

Beta coefficient is a measure of an investment’s systematic risk while the standard deviation is a measure of an investment’s total risk. In a portfolio of investments, **beta coefficient is the appropriate risk measure because it only considers the undiversifiable risk**.

## Is beta same as variance?

**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 difference between standard deviation and beta?

Beta vs Standard Deviation

**Beta shows the sensitivity of a fund’s, security’s, or portfolio’s performance in relation to the market as a whole.** Standard deviation measures the volatility or risk inherent to stocks and financial instruments.
