In these cases, then, the change in price of an option relative to the change in the price of its underlying asset is not constant. (True also – but here, far less pronounced – for volatility, time to expiration, and other factors.) Thus “beta” here, calculated traditionally, would vary constantly as the price of the underlying changed. Covariance measures how the stock moves in relation to the market, while variance measures how far a stock fluctuates compared to its mean.
Relationship between own risk and beta risk
When long-term market-betas are required, further regression toward the mean over long horizons should be considered.

A beta coefficient shows the volatility of an individual stock compared to the systematic risk of the bitcoin pro south africa entire market. Beta represents the slope of the line through a regression of data points. In finance, each point represents an individual stock’s returns against the market.

Beta (β) is the second letter of the Greek alphabet used to measure the volatility of a security or portfolio compared to the S&P 500 which has a beta of 1.0. A Beta of 1.0 shows that a stock has been as volatile as the broader market. Betas larger than 1.0 indicate greater volatility and betas less than 1.0 indicate less volatility. Essentially, beta expresses the trade-off between minimizing risk and maximizing return. On the other hand, if the market declines 6%, investors in that company can expect a loss of 12%. Whereas Beta relies on a linear model, an out of the money option will have a distinctly non-linear payoff.
- A benchmark index, such as the S&P 500, is chosen to represent the market in the beta calculation.
- Beta can provide some risk information, but it is not an effective measure of risk.
- Beta is calculated using two specific components, covariance and variance.
- Investors should use beta alongside other metrics and analyses to make well-informed investment decisions.
- It is an indicator of a stock’s systematic risk which is the undiversifiable risk inherent in the financial system as a whole.

Beta can be used to indicate the contribution of an individual asset to the market risk of a portfolio when it is added in small quantity. It refers to an asset’s non-diversifiable risk, systematic risk, or market risk. Levered beta (equity beta) is a measurement that compares the volatility of returns of a company’s stock against those of the broader market. In other words, it is a measure of risk, and it includes the impact of a company’s capital structure and leverage. Equity beta allows investors to assess how sensitive a security might be to macro-market risks. For example, a company with a β of 1.5 denotes returns that are 150% as volatile as the market it is being compared to.
The value of any stock index, such as the Standard & Poor’s 500 Index, moves up and down constantly. At the end of the trading day, we conclude that “the markets” were up or down. An investor considering buying a particular how to set up bitcoin stock may want to know whether that stock moves up and down just as sharply as stocks in general. It may be inclined to hold its value on a bad day or get stuck in a rut when most stocks are rising. Beta is a measure of the expected movement of a stock relative to the market as a whole. A beta greater than 1.0 implies that the stock is more volatile than the market, whereas a beta less than 1.0 indicates that the stock is less volatile.
The S&P 500 is used as the measure because of the high number of large-cap stocks included in the index and the broad number of sectors included. The Dow Jones Industrial Average (DJIA) has also previously been the main measure of the market, but it has fallen out of favor since it only includes 30 companies and is very limited in its breadth. In recent years, the outperformance of FAANG stocks has made the Nasdaq 100 a popular beta measure among investors and traders.
Financial analysis
Covariance equals the product of standard deviation of the stock returns, standard deviation of the market returns and their correlation coefficient. The beta (β) of an investment security (i.e., a stock) is a measurement of its volatility of returns relative to the entire market. It is used as a measure of risk and is an integral part of the Capital Asset Pricing Model (CAPM). A company with a higher beta has greater risk and also greater expected returns. While the beta coefficient is a valuable tool for assessing systematic risk, it has limitations.
Active traders typically look for stocks with higher volatility than the broader stock market to exploit short-term price fluctuations. Scanning for stocks that have a beta above 2 quickly finds suitable trading candidates that move twice as much as the S&P 500 Index. Traders can use sites like Finviz.com that provides a free screener to run a scan. Many consider stocks in the utility sector to have betas less than 1 since they’re not very volatile. Gold, on the other hand, is quite volatile but has tended to move inversely to the market. Lower beta stocks fogbyte lda lisbon with less volatility do not carry as much risk, but they generally provide less opportunity for a higher return.
