For example, professional fund managers say there’s more to returns than risk relative to the market. Alpha measures the fund’s “excess return” over and above what the market, beta, and the risk-free rate would suggest. To get a deeper perspective on risk and return, consider the Sharpe ratio (and its cousin, the Sortino ratio). An asset with a negative beta is expected to move inversely to the benchmark (it’s negatively correlated).
Rebate rates vary monthly from $0.06-$0.18 and depend on your current and prior month’s options trading volume. Alpha is another measure of risk in addition to beta that measures returns after adjusting for overall market volatility and random fluctuation. An alpha calculation of zero suggests that a stock has earned a return equal to the risk. A negative alpha may mean the investment’s risk was not worth the return. A stock with a high Beta has the potential to generate significantly high returns. However, a high Beta stock is also likely to be more volatile than the overall market.
Like most investing factors, the definition of a good beta in a stock depends on each investor’s goals, risk tolerance and timeline. High- or low-beta stocks aren’t necessarily good or bad; they move in different fashions. Since the benchmark is always 1 in the beta calculation, high beta stocks will have a value greater than 1, and low beta stocks will have a value lesser than 1. The resulting beta coefficient will be greater than or lower than 1 since 1 equals the market return (i.e., the annual average return of the S&P 500).
In this case, we can say that the fund manager of Fund A has added more value with active management. This article does not provide any financial advice and is not a recommendation to deal in any securities or product. Investments may fall in value and an investor may lose some or all of their investment. The Morningstar Rating is a measure of a fund’s risk-adjusted return, relative to similar funds. Funds are rated from 1 to 5 stars, with the historical best performers receiving 5 stars and the worst performers receiving a single star. This can help make it easy to decide which stocks might be right for you.
Variance measures the plus500 forex review volatility of an individual stock’s price over time. In the case of calculating beta, you’ll use the variance of the stock market itself (or the S&P 500 index) as your benchmark index fund. If an asset has a beta of, say, 2, and your CAPM calculation predicts an S&P 500 return of 10%, then the model might forecast an asset return of 20%.
Beta Calculation
The S&P 500’s 500 constituents will each have different betas based on how they moved in relation to the index over a set timeframe. Companies whose share prices were less volatile than the S&P 500 will have a beta value under 1.0. Conversely, share prices that were more volatile than the S&P 500 will have beta values over 1.0.
- Output from Alpha should not be construed as investment research or recommendations, and should not serve as the basis for any investment decision.
- Beta is an essential component of the CAPM, a model used to calculate expected returns based on an asset’s risk relative to the market.
- Growth-oriented investors are attracted to higher beta funds as they promise the potential to deliver higher returns when the markets are up.
- For example, an ELSS fund may be benchmarked against indices like S&P BSE 500 – TRI or NIFTY 500 – TRI.

A stock beta of 1.5 means that a stock’s volatility is 1.5 times that of the overall stock market. The price is moving up or down at a higher rate than the S&P 500 has over the past few years. Very few investors have true alpha, and it typically takes a decade or more to be sure. Buffett focused on value investing, dividend growth, and «growth at a reasonable price» strategies during his career. A study of Buffett’s alpha found that he tended to use leverage with high-quality and low-beta stocks.
How to Calculate Beta?
- In the United States, most stocks and funds use the S&P 500 as their benchmark, as the index represents a broad cross section of the U.S. stock market.
- In statistics, beta values are the standardized regression coefficients.
- This is especially helpful when valuing companies that are significantly different in terms of debt structure or when assessing the risk of a business sector as a whole.
- Many brokerage firms calculate the betas of securities they trade and publish their calculations in a beta book.
- So when the S&P 500 rises, the CAPM would suggest the asset will fall.
Beta values can shift over time because they’re tied to market fluctuations. Investors use beta to align their portfolios with their risk tolerance levels, targeting high-beta stocks for potentially higher returns with more risk, or low-beta stocks for added stability. Beta is used in the capital asset pricing model (CAPM), a widely used method for pricing risky securities and for generating estimates of the expected returns of assets, particularly stocks. The CAPM formula uses the total average market return and the beta value of the stock to determine the rate of return that shareholders might reasonably expect based on perceived investment risk. In this way, beta can impact a stock’s expected rate of return and share valuation. Alpha is used to measure the amount of excess returns generated by an investment relative to its benchmark, meanwhile beta tells us about the level of volatility in the fund relative to the market.
How Investors Use Beta
For example, a bond ETF’s beta with the S&P 500 as the benchmark would not be helpful to an investor because bonds and stocks are too dissimilar.

Since a single integer represents beta, it’s easily interpreted and factored into stock and portfolio analysis. You can easily recognize a beta of 1.35 as 35% more volatile than its benchmark. The true market-beta is essentially the average outcome if infinitely many draws could be observed. On average, the best forecast of the realized market-beta is also the best forecast of the true market-beta. In fund management, adjusting for exposure to the market separates out the component that fund managers should have received given that they had their specific exposure to the market. This is measured by the alpha in the market-model, holding beta constant.
A beta of 1.7 will move, on average, 70% greater than the market return. Therefore, if the market returns 10%, a stock with a beta of 1.7 will return 17%. A beta of 1.3 will move, on average, 50% more than the market return. Therefore, if the market returns 10%, a stock with a beta of 1.3 will return 13%.

Reinvestment into new Treasuries is subject to market conditions and may result in different yields. As a general rule, the price of Treasuries moves inversely to changes in interest rates. Before investing, you should consider your tolerance for these risks and your overall investment objectives.
Q. How is Beta used in the Capital Asset Pricing Model (CAPM)?
This puts high Beta stocks in the high-risk, high-reward category. Traders & investors must thus evaluate their risk profile before adding high Beta stocks to their portfolios. The second method involves directly solving for beta using its formula. In Excel, you should employ the sample covariance and variance functions, namely COVARIANCE.S and VAR.S, for this calculation. Adding stocks with a beta greater than 1 would add more volatility relative to the market (and the potential for higher returns). A high beta isn’t inherently good or bad—it depends on the investor’s risk tolerance.
Beta less than 1 learn options trading means the asset is less sensitive than the benchmark. In other words, the stock would move with the benchmark, but not to the same degree. If the S&P 500 rises 5%, the CAPM suggests the stock would rise 1.25%. Download the stock prices and NASDAQ index prices for the past couple of years.
What you Need to Know Before Using a Stock Trading App?
A portfolio consisting entirely of high-beta stocks can be highly volatile and subject to significant market fluctuations. Conversely, a portfolio with primarily low-beta stocks might offer stability but potentially limit returns. Balancing high and low-beta assets allows investors to tailor their portfolios to their specific risk-reward preferences. While beta can offer useful information when evaluating a stock, it does have some limitations.
In this article, we’ll take a look at what beta is, how it can be useful, and some examples of beta in real-world stocks. Value investors scorn the idea of beta because it implies that a stock that has fallen sharply in value is riskier than it was before it fell. Beta says nothing about the price paid for the stock in relation to fundamental factors like changes in company leadership, new product discoveries, or future cash flows. To calculate the beta of a security, the covariance between the return of the security and the return of the market must be known as well as the variance of the market returns.
