Is portfolio beta truly just the weighted average of stock betas? If so, is there a way to distinguish betas based on composition?
Is the beta of a portfolio the weighted average?
Portfolio beta is a measure of the overall systematic risk of a portfolio of investments. It equals the weighted-average of the beta coefficient of all the individual stocks in a portfolio.
What is a portfolio beta in stocks?
According to Investopedia, beta is defined as “a measure of the volatility, or systematic risk, of a security or a portfolio in comparison to the entire market or a benchmark.” This definition, as usual, is a mouthful for most investors who are simply trying to understand certain aspects of risk in their portfolio.
How do you calculate the weighted average portfolio beta?
How to Calculate the Weighted Average Beta of a Portfolio

- Multiply the stock beta by its weight to find the weighted beta.
Why a portfolio’s beta is the weighted average of the betas of the shares in the portfolio?
A stock with a beta of 1 has approximately the same risk and volatility as the market as a whole. Betas higher than 1 are more risky, while betas lower than 1 are less risky. Calculating the weighted average beta of a portfolio allows you to measure the overall risk of your portfolio.
What is the weighted beta?
Beta weighting allows you to assess all of your positions relative to a move in the market (when weighted to SPY) or a specific symbol. In other words, it tells you the theoretical dollar move of your portfolio or position given a $1 move up in the underlying that you are beta-weighting to.
What is the meaning of beta explain what a portfolio beta of 1.5 means?

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.
How do you interpret a stock beta?
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.
What does a β of 1.3 mean?
The beta for a stock describes how much the stock’s price moves compared to the market. If a stock has a beta above 1, it’s more volatile than the overall market. For example, if an asset has a beta of 1.3, it’s theoretically 30% more volatile than the market.
What is a good portfolio beta?
A beta value that is less than 1.0 means that the security is theoretically less volatile than the market. Including this stock in a portfolio makes it less risky than the same portfolio without the stock.
Why is beta the theoretically correct measure of a stock’s riskiness?
Why is beta the theoretically correct measure of a stock’s risk? Since a stock’s beta coefficient determines how the stock affects the risk of a diversified portfolio, beta is the most relevant measure of any stock’s risk.
What does a beta of 1.20 indicate?
Trading-Glossary. “A measure of a fund’s risk, or volatility, compared to the market which is represented as 1.0. A fund with a beta of 1.20 is 20% more volatile than the market, while a fund with a beta of 0.80 would be 20% less volatile than the market.”
What is the beta of stock B?
The portfolio beta is equal to the market beta. Stock A has an expected return of 22.6 percent and has a beta of 1.48. Stock B has a beta of . 72.
What if beta is less than 1?
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.
What is the importance of beta in portfolio management?

How does systematic risk and beta affect portfolio management and asset allocation?
The beta of a stock or portfolio will tell you how sensitive your holdings are to systematic risk, where the broad market itself always has a beta of 1.0. High betas indicate greater sensitivity to systematic risk, which can lead to more volatile price swings in your portfolio, but which can be hedged somewhat.
Which statement is true regarding a portfolio that has a beta of +1?
The best answer is B. Beta is a measure of market volatility. A beta of “1” indicates that a security has the same volatility as the “market.” Thus, a beta of “1” indicates that the stock’s volatility matches that of the market (and thus has the same market risk, which is the same as systematic risk).
Does beta measure systematic or unsystematic risk?
Beta is the standard CAPM measure of systematic risk. It gauges the tendency of the return of a security to move in parallel with the return of the stock market as a whole. One way to think of beta is as a gauge of a security’s volatility relative to the market’s volatility.
