Our estimates are based on past market performance, and past performance is not a guarantee of future performance. Obviously if ur using the CAPM to arrive at cost of capital in a situation of the firm having negative beta, ur cost of capital will be lower than ur risk free rate. Beta measures the volatility of a stock compared with the volatility of the market as a whole.

A slip-up could result in the share price tumbling dramatically. Likewise, a small hint of good news can lead to another big rally. More conservative investors or those that wish to soon tap into their funds will likely prefer low-beta stocks. These kinds of stocks historically tend to not fluctuate much in value. They are companies that consistently deliver steady revenues and profits in times of economic expansion and hardship.
For example, to hedge out the market-risk of a stock with a market beta of 2.0, an investor would short $2,000 in the stock market for every $1,000 invested in the stock. Thus insured, movements of the overall stock market no longer influence the combined position on average. Beta measures the contribution of an individual investment to the risk of the market portfolio that was not reduced by diversification. It does not measure the risk when an investment is held on a stand-alone basis. Beta plays a significant role in the capital asset pricing model (CAPM), which describes the relationship between market, or systemic risk, and expected return.
Usually, cyclical stocks have a beta above one, while defensive stocks have a beta lower than one. The beta can even be negative, which would mean that a stock has a negative correlation with the markets. However, over long periods, it isn’t practical for any stock to have a negative beta. Talking of risk, we can broadly divide it into systematic risk and unsystematic risk. As the name suggests, it’s the risk related to the “system,” which in this case is the stock market.
Editorial integrity
However, for investors with long-term horizons, it’s less useful. A company behind the next big thing typically commands a high valuation. Investors buy the stock based on it living up to its potential, which requires lots of uncertain factors going its way.
- A beta of 1.0 indicates that the security’s price will move with the market.
- Other funds concentrate on stocks in sectors that intrinsically have low betas, such as Utilities Select Sector SPDR Fund and Global X NASDAQ 100 Covered Call ETF.
- Beta measures risk in the form of volatility against a benchmark and is based on the principle that higher risk come with higher potential rewards.
- This scenario is rare just because an asset rarely displays a negative covariance with the group it is a part of.
Is there any other context you can provide?
Passive strategies, such as index funds, aim to replicate the performance of a specific market index. The beta of these funds closely matches that of the underlying index. They may deliberately select securities with beta values that deviate from the market, depending on their investment goals and can beta be negative expectations. By including a mix of assets with varying beta values, investors can create a balanced portfolio that aligns with their risk preferences. A well-diversified portfolio can reduce overall risk and improve the chances of achieving a consistent return on investment.
The median Altman Z-score of companies in 2007 was 1.81, which is very close to the threshold that would indicate a high probability of becoming bankrupt; Altman’s calculations led him to believe a crisis would occur. The offers that appear on this site are from companies that compensate us. But this compensation does not influence the information we publish, or the reviews that you see on this site. We do not include the universe of companies or financial offers that may be available to you. But remember that beta is a backward-looking measure of one specific type of risk. Consider looking at a stock’s fundamentals along with its beta when deciding whether to add it to your portfolio.
Advantages of Using Beta as a Proxy for Risk
E.g. a stock of beta 0.75 if added to a portfolio of beta 1.5 would still reduce the overall portfolio risk. A more intuitive way of thinking about this is that a negative beta investment represents insurance against some macro economic risk that affects the rest of your portfolio adversely. Stocks with negative betas move in the opposite direction of the market. Beta is often calculated using something called regression analysis plotting, which compares a stock’s returns against those of the overall market. Beta allows investors to understand the systemic market risk of an individual security.
