On this planet of investing, volatility issues.
Traders are reminded of this each time there’s a downturn within the broader market and particular person shares which are extra risky than others expertise monumental swings in value in each instructions.
That volatility can enhance the danger in a person’s inventory portfolio relative to the broader market.
The volatility of a safety or portfolio in opposition to a benchmark – is known as Beta. Briefly, Beta is measured through a components that calculates the value threat of a safety or portfolio in opposition to a benchmark, which is usually the broader market as measured by the S&P 500 Index.
It’s useful in understanding the general value threat stage for traders throughout market downturns specifically.
Right here’s how one can learn inventory betas:
A beta of 1.0 means the inventory strikes equally with the S&P 500
A beta of two.0 means the inventory strikes twice as a lot because the S&P 500
A beta of 0.0 means the shares strikes don’t correlate with the S&P 500
A beta of -1.0 means the inventory strikes exactly reverse the S&P 500
Apparently, low beta shares have traditionally outperformed the market… However extra on that later.
You’ll be able to obtain a spreadsheet of the 100 lowest beta shares (together with monetary metrics like price-to-earnings ratios and dividend yields) by clicking on the hyperlink beneath:
This text will talk about how one can calculate beta, the distinction between high-beta and low-beta shares, in addition to particular person evaluation of the one inventory within the S&P 500 Index with unfavourable beta proper now.

Excessive Beta Shares Versus Low Beta
Beta is useful in understanding the general value threat stage for traders throughout market downturns specifically. The decrease the Beta worth, the much less volatility the inventory or portfolio ought to exhibit in opposition to the benchmark.
That is useful for traders for apparent causes, notably these which are near or already in retirement, as drawdowns must be comparatively restricted in opposition to the benchmark.
Low or excessive Beta merely measures the dimensions of the strikes a safety makes; it doesn’t imply essentially that the value of the safety stays almost fixed.
Securities might be low Beta and nonetheless be caught in long-term downtrends, so that is merely yet another instrument traders can use when constructing a portfolio.
Intuitively, it could make sense that prime Beta shares would outperform throughout bull markets. In any case, these shares must be attaining greater than the benchmark’s returns given their excessive Beta values.
Whereas this may be true over brief durations of time – notably the strongest components of the bull market – the excessive Beta names are typically the primary to be offered closely by traders.
This glorious paper from the CFA Institute theorizes that that is true as a result of traders are in a position to make use of leverage to bid up momentum names with excessive Beta values and thus, on common, these shares have decrease potential returns at any given time.
As well as, leveraged positions are among the many first to be offered by traders throughout weak durations due to margin necessities or different financing issues that come up throughout bear markets.
Whereas excessive Beta names could outperform whereas the market is robust, as indicators of weak point start to indicate, excessive Beta names are the primary to be offered and usually, far more strongly than the benchmark.
Proof suggests that in good years for the market, excessive Beta names seize 138% of the market’s whole returns.
Due to this fact, if the market returned 10% in a yr, excessive Beta names would, on common, produce 13.8% returns. Nonetheless, throughout down years, excessive Beta names seize 243% of the market’s returns.
In the same instance, if the market misplaced 10% throughout a yr, the group of excessive Beta names would have returned -24.3%.
Given this comparatively small outperformance throughout good occasions and huge underperformance throughout weak durations, it’s straightforward to see why we choose low Beta shares.
Whereas low Beta shares aren’t utterly immune from downturns available in the market, it’s a lot simpler to make the case over the long term for low Beta shares versus excessive Beta given how every group performs throughout bull and bear markets.
How To Calculate Beta
The components to calculate a safety’s Beta is pretty simple. The outcome, expressed as a quantity, reveals the safety’s tendency to maneuver with the benchmark.
Beta of 1.00 signifies that the safety in query ought to transfer nearly in lockstep with the benchmark (as mentioned briefly within the introduction of this text).
Beta of two.00 means strikes must be twice as massive in magnitude.
Lastly, a unfavourable Beta signifies that returns within the safety and benchmark are negatively correlated; these securities have a tendency to maneuver in the wrong way from the benchmark.
This form of safety could be useful to mitigate broad market weak point in a single’s portfolio as negatively correlated returns would recommend the safety in query would rise whereas the market falls.
For these traders looking for excessive Beta, shares with values in extra of 1.3 could be those to hunt out. These securities would provide traders a minimum of 1.3X the market’s returns for any given interval.
Right here’s a take a look at the components to compute Beta:
The numerator is the covariance of the asset in query whereas the denominator is the variance of the market. These complicated-sounding variables aren’t truly that troublesome to compute.
Right here’s an instance of the info you’ll have to calculate Beta:
Danger-free charge (sometimes Treasuries a minimum of two years out)
Your asset’s charge of return over some interval (sometimes one yr to 5 years)
Your benchmark’s charge of return over the identical interval because the asset
To indicate how one can use these variables to do the calculation of Beta, we’ll assume a risk-free charge of two%, our inventory’s charge of return of 14% and the benchmark’s charge of return of 8%.
You begin by subtracting the risk-free charge of return from each the safety in query and the benchmark. On this case, our asset’s charge of return web of the risk-free charge could be 12% (14% – 2%). The identical calculation for the benchmark would yield 6% (8% – 2%).
These two numbers – 12% and 6%, respectively – are the numerator and denominator for the Beta components. Twelve divided by six yields a price of two.00, and that’s the Beta for this hypothetical safety.
On common, we’d anticipate an asset with this Beta worth to be 200% as risky because the benchmark.
Fascinated with it one other means, this asset must be about twice as risky than the benchmark whereas nonetheless having its anticipated returns correlated in the identical route.
That’s, returns could be correlated with the market’s general route, however would return double what the market did through the interval.
This might be an instance of a really excessive Beta inventory and would provide a considerably larger threat profile than a mean or low Beta inventory.
Beta & The Capital Asset Pricing Mannequin
The Capital Asset Pricing Mannequin, or CAPM, is a standard investing components that makes use of the Beta calculation to account for the time worth of cash in addition to the risk-adjusted returns anticipated for a specific asset.
Beta is a vital part of the CAPM as a result of with out it, riskier securities would seem extra favorable to potential traders as their threat wouldn’t be accounted for within the calculation.
The CAPM components is as follows:
The variables are outlined as:
ERi = Anticipated return of funding
Rf = Danger-free charge
βi = Beta of the funding
ERm = Anticipated return of market
The chance-free charge is identical as within the Beta components, whereas the Beta that you simply’ve already calculated is solely positioned into the CAPM components.
The anticipated return of the market (or benchmark) is positioned into the parentheses with the market threat premium, which can be from the Beta components. That is the anticipated benchmark’s return minus the risk-free charge.
To proceed our instance, right here is how the CAPM truly works:
ER = 2% + 2.00(8% – 2%)
On this case, our safety has an anticipated return of 14% in opposition to an anticipated benchmark return of 8%.
In concept, this safety ought to vastly outperform the market to the upside however understand that throughout downturns, the safety would undergo considerably bigger losses than the benchmark.
If we modified the anticipated return of the market to -8% as an alternative of +8%, the identical equation yields anticipated returns for our hypothetical safety of -18%.
This safety would theoretically obtain stronger returns to the upside however actually a lot bigger losses on the draw back, highlighting the danger of excessive Beta names throughout something however robust bull markets.
Whereas the CAPM actually isn’t excellent, it’s comparatively straightforward to calculate and offers traders a way of comparability between two funding options.
Evaluation On The S&P 500 Inventory With Destructive Beta
Now, we’ll check out the S&P 500 inventory that at the moment has a unfavourable beta worth. On the time of publication, there was just one inventory within the S&P 500 Index with a unfavourable beta worth, in accordance with a inventory display screen from FinViz.
Destructive Beta Inventory: Biogen Inc. (BIIB)
Biogen is a large-cap pharmaceutical firm with a present market cap of roughly $32 billion. Biogen doesn’t at the moment pay a dividend. The inventory has a unfavourable Beta worth of -0.04 proper now.
Within the 2024 first quarter, Biogen reported GAAP earnings-per-share development of 1% and adjusted EPS development of 8% year-over-year. First quarter income got here to $2.3 billion, down 7% year-over-year. Product income declined 3% from the identical quarter final yr.
For the complete yr, Biogen reaffirmed steering which requires adjusted EPS in a variety of $15.00 to $16.00. On the midpoint, Biogen expects EPS development of roughly 5% for 2024.
Last Ideas
Beta is likely one of the most widely-used measures of inventory market volatility. Beta could be a precious instrument for traders when analyzing shares for inclusion of their portfolios.
Shares with unfavourable betas are anticipated to maneuver inversely to the broader market. Destructive-beta shares may very well be notably interesting in a recession or a market downturn.
