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 seeking short term opportunities with a swing trading with the market. Beta can be helpful as a gauge of a stock’s volatility relative to the market or a particular portfolio and is a readily available measure. Like any statistic, though, it should be used as a guide and not as a precision predictor of future price action.

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. High beta stocks make portfolios riskier but increase the chance of higher returns.
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.

Evaluating a Stock’s Beta as an Investor
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.

If its beta were less than 1, it would be expected to be less volatile than the index — smaller increases and decreases.
Risk is an unavoidable part of investing, but it’s also the driver of your returns. Investors look for ways to understand risk, mitigate it and measure it. Beta analysis can be a useful way to manage the level of risk in your portfolio, but like any financial technique, it’s not perfect.

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 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.
