To calculate CAPM, multiply the stock’s beta by the market risk premium, which is represented by (MR – RFR). Doing this yields the amount of systemic risk a security introduces into a portfolio and how that risk could impact the expected return.

Beta plays a significant role in the capital asset pricing model (CAPM), which describes the relationship between market, or systemic risk, and expected return.
- High- or low-beta stocks aren’t necessarily good or bad; they move in different fashions.
- A beta higher than one shows that a stock’s price is more volatile than the market.
- Moreover, a stock’s level of volatility may change over time as its circumstances change.
- For most investors, downside movements are a risk, while upside ones mean opportunity.
- And since short-term traders can profit from big swings in either direction, you can use beta in multiple-day and swing trading strategies.
You don’t want to take excessive risk in the portfolio, but you’re willing to withstand a little volatility to outperform the S&P 500. If you’re still asking, “What is alpha and beta in stocks?” here’s an example https://www.day-trading.info/best-assets-to-have-the-5-best-income-generating/ to help better expand the concept. To further illustrate the stock beta meaning, consider the assets in an index as cars racing down a congested highway with the benchmark as the road’s center line.
It gives investors a way to relate expected return to the level of risk they assume. Beta is used in the capital asset pricing model (CAPM), which describes the relationship between systematic risk and expected return for assets (usually stocks). CAPM is widely used as a method for pricing risky securities and for generating estimates of the expected returns of assets, considering both the risk of those assets and the cost of capital. Another troubling factor is that past price movement is a poor predictor of the future. Betas are merely rear-view mirrors, reflecting very little of what lies ahead. Furthermore, the beta measure on a single stock tends to flip around over time, which makes it unreliable.
Evaluating a Stock’s Beta as an Investor
Consider a firm that has long been considered a safe company with a consistently low beta. The firm then enters a new sector and takes on major debt in its next few years. The company’s low beta level doesn’t factor in this new risk because of the beta calculation’s inherent reliance on past information. This indicates that the 1 gbp to usd or 1 british pound to us dollar stock may respond in the opposite direction of the overall market. Using the previous example, you could expect the stock’s price to go up if the S&P 500 goes down and vice versa. It’s tempting to just look at the number on your brokerage’s app or website and assume you know how volatile that particular stock or asset is.

Therefore it plays a pivotal role in portfolio construction. Investors use beta to see whether the price of a security is moving in the same direction as the rest of the market. It also provides insights about how volatile—or how risky—a stock is relative to the rest of the market. If its beta were less than 1, it would be expected to be less volatile than the index — smaller increases and decreases.
Cars may drift away from the center line at various rates as they head toward their destination. Sticking toward the center line might be safer, but some cars are willing to sacrifice a little safety and move away from the line if it gets them to their destination faster.

Including this stock in a portfolio makes it less risky than the same portfolio without the stock. For example, utility stocks often have low betas because they tend to move more slowly than market averages. A stock with a beta equal to 1 assumes its price moves hand-in-hand with the market.

Like any statistic, though, it should be used as a guide and not as a precision predictor of future price action.

Beta effectively describes the activity of a security’s returns as it responds to swings in the market. 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. Remember, beta measures how volatile a stock’s price may be in relation to a market benchmark.
Using beta to evaluate a stock’s risk

Deductive logic would indicate that the beta of a stock would refer to underperformance. In this article, you’ll learn the beta meaning, its formulation and how to use beta in stock market analysis. Moreover, a stock’s level of volatility may change over time as its circumstances change. This makes beta less practical when looking at long-term investments.
