Including such stocks in a portfolio can help to mitigate overall risk. the camarilla pivot points indicator It’s crucial to realize that high or low beta frequently leads to market outperformance. A fund with lots of growth stocks and high beta will usually beat the market during a good year for stocks. Similarly, a conservative fund that holds bonds will have a low beta and typically outperform the S&P 500 during a poor year for the market.
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. Granted, for traders looking to buy and sell stocks within short time periods, beta is a fairly good risk metric. However, for investors with long-term horizons, it’s less useful.
You’ll find this alongside other metrics of a stock’s price when doing your research — which you should always do. Beta can help give investors an idea of the risk in a given stock, and it’s a useful, if incomplete, way of doing so. During economic cycles, some sectors perform better than others. Investors can use beta to determine which sectors to overweight or underweight in their portfolios, depending on their outlook for the broader market. But just like anything in the world of investing, it’s never that black-and-white. And past good performance is never a guarantee of continued or greater performance in the future.
The well-worn definition ice bofa us corporate index option of risk is the possibility of suffering a loss. Of course, when investors consider risk, they are thinking about the chance that the stock they buy will decrease in value. The trouble is that beta, as a proxy for risk, doesn’t distinguish between upside and downside price movements.
Beta in Portfolio Diversification
Every investor needs to have a good understanding of their own risk tolerance, and a knowledge of which investments match their risk preferences. Similarly, a convert british pounds to hungarian forints high beta stock that is volatile in a mostly upward direction will increase the risk of a portfolio, but it may increase gains. Investors who beta to evaluate a stock also evaluate it from other perspectives—such as fundamental or technical factors—before assuming it will add or remove risk from a portfolio. Beta is the volatility of a security or portfolio against its benchmark. It’s a numerical value that signifies how much a stock price jumps around. The higher the value, the more the company tends to fluctuate in value.
Investment professionals use this expected return, in conjunction with other valuation methods, as a basis for investment decisions. Open your spreadsheet and enter the date of each day in your specified timeframe. Stock prices go in the second column and benchmark prices in the third. Next, calculate the daily price changes for each (subtract current day price from previous day price, divide by the previous day price and multiply by 100). Unsystemic risk is unique to each security and can be diversified away in an investment portfolio.
- For each entry, subtract that day’s cost price from that of the previous day.
- High-beta stocks can outperform the market, underperform the market or even match the market return over time if the route getting there is circuitous enough.

- R-squared is a statistical measure that compares the security’s historical price movements to the benchmark index.
- It measures the systematic risk of a security or a portfolio compared with an index like the S&P 500.
However, suppose the fund manager then underperforms the market by 2% over the next three years. The original appearance of alpha was because of sample size neglect.

Meanwhile, alpha compares a particular stock’s actual performance to the market’s performance. Let us take, for example, an investor who wants to calculate the beta of Nike compared to the S&P 500. Based on recent six-year data, Nike and S&P 500 have a covariance of 18.75, and the variance of Nike is 48.06.
Using Beta to Understand a Stock’s Risk
A beta value of 1.5 implies that the stock is 50% more volatile than the broader market. That means higher than average risk and the potential for greater upside. Beta is a measure of a stock’s volatility in relation to the overall market. By definition, the market, such as the S&P 500 Index, has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. A stock that swings more than the market over time has a beta above 1.0. If a stock moves less than the market, the stock’s beta is less than 1.0.
The overall market has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. A financial professional will offer guidance based on the information provided and offer a no-obligation call to better understand your situation.

Both companies presented have betas of less than one, meaning that they are less volatile than the market in general.
Variance measures how far a stock fluctuates when compared to its mean. In the beta calculation, the market’s movement is often the one being measured by the variance. A negative alpha means the investment underperformed relative to its expected return based on its beta. We often hear the terms alpha and beta when talking about investments. These are two different measures that are part of the same equation derived from a linear regression. Don’t worry if that sounds complicated, we’ll explain it all in this article.
Adding this type of stock to a portfolio will raise its risk, but it may also improve its expected return. Stocks tend to be more volatile in the short term but produce relatively consistent returns over time. In that case, you’ll be more interested in short-term beta measurements since you have significantly shorter time horizons than a long-term investor planning for retirement. Likewise, low-beta stocks may be less volatile than the market but could still outperform or underperform market averages over the specified period. A high beta isn’t inherently good or bad—it depends on the investor’s risk tolerance.
Say your benchmark, or the market to which you’re comparing a stock, is the S&P 500. If the stock you’re analyzing has a beta of 2, that means the stock is twice as volatile as the market. If the S&P 500 goes up by 10% next year, you can expect the stock price to go up by 20%. However, it could plummet by just as much if the S&P 500 goes down by 10%. Covariance is how you measure a changing relationship between two entities. In this case, covariance will show you how changes in stock returns relate to changes in market returns.
Beta can be used to help diversify a portfolio and make better investment decisions. However, beta is only one measure of risk and should not be used in isolation since it only measures past performance. This stock has a beta of 1.5, which is 50% more volatile than the market. However, this also means it could earn 50% more than the market can return in a given period. A beta value greater than 1.0 signifies that the theoretical volatility of the security’s price exceeds that of the market.
