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. Positive alpha indicates that the investment has outperformed the market, while negative alpha indicates underperformance. Positive alpha suggests that the investment has provided returns higher than expected given How to buy hex coin its risk level, while negative alpha suggests the opposite.
Defining Alpha
Put atfx trading platform another way, it can be difficult to feel like the odds are in investors’ favor when volatility is screaming higher and stocks are rolling over. If the beta is below 1, the stock either has lower volatility than the market, or it’s a volatile asset whose price movements are not highly correlated with the overall market. The price of Treasury bills (T-bills) has a beta lower than 1 because T-bills don’t move in relation to the overall market.
Beta measures the volatility or risk of a particular asset compared to the market. In other words, beta measures the extent of a security’s price movement relative to the market. Short-term day or swing traders or long-term investors can use beta. In the example above, we showed how to use beta to adjust the overall volatility of a portfolio by adding a stock within a particular beta range. Using beta allows investors to adjust the risk profile of their portfolio through a metric with simple values that are easy to interpret. Deductive logic would indicate that the beta of a stock would refer to underperformance.
Alpha and beta measure investment performance and market sensitivity, respectively, while standard deviation measures the dispersion of returns around the mean. Standard deviation provides insight into the volatility of an investment’s returns but does not account for market risk or excess return. While a positive alpha is always more desirable than a negative alpha, beta isn’t as clear-cut. Risk-averse investors such as retirees seeking a steady income are attracted to lower beta. Risk-tolerant investors who seek bigger returns are often willing to invest in higher beta stocks. Beta can be a useful tool in analyzing a stock, but it has its limitations.
Beta can determine a security’s short-term risk and analyze volatility. However, beta is calculated using historical data points and is less meaningful for investors looking to predict a stock’s future movements for long-term investments. A stock’s volatility can change significantly over time, depending on a company’s growth stage and other factors.

In this article, you’ll learn the beta meaning, its formulation and how to use beta in stock market analysis. Alpha and beta are related in that alpha represents the excess return of an investment beyond what would be expected based on its level of risk, as measured by beta. Beta helps contextualize alpha by quantifying the investment’s risk relative to the market. In this formula, covariance is used to measure the correlation in price moves of any two stocks. A positive covariance means the stocks tend to move in lockstep, while a negative covariance means they move in opposite directions.
Further, when the VIX finally falls significantly, it can also point to favorable returns for the S&P 500. In fact, one-day declines of 20% or more in the VIX are met by an S&P 500 win-rate of more than 83% when looking one year down the road. In that table, notice how well equities have performed a year later, with the S&P 500 up more than 90% of the time following these VIX spikes.

The trouble is that beta, as a proxy for risk, doesn’t distinguish between upside and downside price movements. For most investors, downside movements are a risk, while upside ones mean opportunity. A negative beta is when an asset moves in the opposite direction of the stock market.
Sure, there are variations on beta depending on things such as the market index used and the time period measured. But broadly speaking, the notion of beta is fairly straightforward. It’s a convenient measure that can be used to calculate the costs of equity used in a valuation method. Numerically, it represents the tendency for a security’s returns to respond to swings in the market. 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.
