Ted Theodore first wrote about value versus momentum stocks way back in 1984, however nearly 40 years later, there nonetheless is not any actual consensus amongst buyers or lecturers on what’s driving both technique.
That’s not because of an absence of analysis. Hundreds of papers have scrutinized fairness elements throughout markets and asset courses, and a few have analyzed methods going again greater than 200 years.
A part of the issue is that efficiency drivers have been recognized however lack widespread acceptance from practitioners. That’s comprehensible. If what’s driving a method’s returns is crystal clear, fund managers can be out of labor when the atmosphere for his or her funding model turns unfavorable. They’re higher off remaining publicly imprecise about efficiency drivers, as that helps to retain their belongings underneath administration (AUM).
A second challenge is that efficiency drivers are by no means crystal clear. Finance isn’t a tough science with immutable, gravity-like legal guidelines. Markets change constantly and historic efficiency and developments are usually not completely replicable. So in relation to efficiency drivers, finance practitioners should reside with comparatively low requirements of proof.
Our framework for figuring out a efficiency driver consists of 4 standards:
- It ought to have a sound financial foundation.
- It ought to work on common, however not on a regular basis.
- It ought to be implementable.
- It ought to maintain when examined throughout time, markets, and asset courses.
So what’s the worth issue’s key efficiency driver? On what proof can we base that willpower?
What Is Driving the Worth Issue?
The worth issue generates constructive returns when low-cost shares outperform costly ones. So when does that occur?
Low-cost corporations are usually troubled corporations. In any other case, they wouldn’t commerce at low valuations. Their points could be temporal or structural: an overleveraged steadiness sheet or being a part of an trade in decline, for instance. Both means, buyers will discover these shares uncomfortable to carry for the reason that related information stream and dealer scores will are usually downbeat.
Meaning buyers are almost definitely to threat shopping for questionable corporations after they’re extra assured concerning the financial system and the inventory markets. When the financial system is heading into recession, buyers are likely to favor corporations with high quality or development traits. Put one other means: Threat sentiment is the first efficiency driver of the worth issue.
There are various variables with which to measure threat sentiment. We deal with three: inventory market volatility, inventory market skewness, and the yield curve.
The Worth Issue and Realized Inventory Market Volatility
We constructed a worth issue out of the most affordable and most costly 10% of shares within the US inventory market as measured by price-to-book ratios utilizing knowledge from the Kenneth R. French Data Library. We then calculated the Z-score of inventory market volatility utilizing a three-month lookback.
A lot of the worth issue’s constructive returns from 1926 to 2020 will be attributed to lowering volatility. This relationship isn’t good, nonetheless: Between 1931 and 1943, worth issue returns fell amid rising volatility. However from then on, returns have been constantly unfavourable when volatility was on the upswing.

These outcomes present some help for the premise that threat sentiment is the important thing efficiency driver of the worth issue: Inventory market volatility tends to rise when financial volatility will increase, which generally happens because the financial system deteriorates. Buyers favor lower-risk investments throughout such durations and thus are likely to shun low-cost shares.
The Worth Issue and Inventory Market Skewness
We subsequent analyzed worth issue returns within the context of inventory market skewness, which we calculated with a 12-month lookback. Inventory market skewness is a extra summary metric, nevertheless it merely implies that buyers could also be extra cautious within the aftermath of a inventory market crash.
With its lengthy upward actions and few however steep downturns, the US inventory market is extra negatively than positively skewed over time. Virtually the entire worth issue’s constructive returns happen amid durations of constructive skewness, when no extreme crashes have not too long ago occurred. Buyers really feel protected and are extra prepared to guess on troubled companies.

The Worth Issue and the Yield Curve
We calculated the yield curve because the distinction between the 10-year and two-year US Treasury charges. A downward-sloping yield curve is related to declining financial development and an inverted yield curve interpreted as a number one indicator of recession. Sadly, the information solely goes again to 1976, which limits the scope of our evaluation.
We calculated the yield curve’s slope with a Z-score utilizing a three-month lookback. We discovered that the majority the constructive returns of the worth issue occurred when the yield curve was upward sloping, or when financial circumstances have been extra bullish.

Combining Metrics for Issue Threat Administration
Based mostly on these findings, buyers may contemplate making use of these metrics to time the worth issue. We advocate approaching this from a threat reasonably than a return perspective. That’s, we advise specializing in avoiding important drawdowns when the market atmosphere for proudly owning low-cost shares is extra unfavourable.
Our multi-metric threat administration framework solely allotted to the worth issue when a mix of inventory market volatility, market skewness, and yield curve have been favorable. Particularly, we modeled three situations wherein one, two, or three indicators are required for an element allocation. With out the required indicators, zero-interest money was held as a substitute.
Given the boundaries of our yield curve knowledge, three constructive indicators representing a market atmosphere with falling market volatility, constructive market skewness, and an upward-sloping yield curve was solely doable since 1976.
Our findings are fairly typical for multi-metric frameworks: The extra filters, the extra constant the returns however the decrease the publicity to the issue.
Requiring a minimum of one constructive sign generated returns akin to that of the buy-and-hold worth issue. Nonetheless, with two and even three indicators, returns have been rather more in step with considerably lowered drawdowns. The general returns have been decrease than these of the worth issue because of each excessive money allocations and the restricted yield curve knowledge.
Multi-Metric Threat Administration Framework for the Worth Issue
We additionally evaluated the efficiency of the worth issue when the indicators have been unfavourable. This might be used to probably quick the issue by shopping for costly and promoting low-cost shares.
A one-signal requirement generated efficiency consistent with the buy-and-hold worth issue. Two or three indicators, however, yielded constant losses, which represents a market atmosphere of accelerating volatility, unfavourable market skewness, and a downward sloping yield curve.
Multi-Metric Threat Administration Framework for the Worth Issue: Quick Alerts
All informed, this evaluation is way from good. We now have not completely examined the framework for robustness. We might use price-to-earnings as a substitute of price-to-book for inventory choice, change the lookback durations, embody transaction prices, apply the framework to worldwide markets and different asset courses, and so forth.
However we’ve used frequent risk-measurement variables and publicly obtainable knowledge, made few assumptions, and utilized our technique to greater than 90 years of monetary historical past. This gives some consolation within the significance of those outcomes.
One clearly defective assumption is our same-day utility of the buying and selling indicators. That is not possible to implement since adjustments within the variables and inventory markets happen concurrently.
Identical-Day vs. Subsequent-Day Buying and selling: CAGRs, 1926–2020
To make the indicators extra life like, we analyzed what would happen if the trades have been carried out the subsequent day. That led to important reductions within the CAGRs for the frameworks requiring one or two constructive indicators, however not for 3 constructive indicators.
Understanding what drives worth issue efficiency is immensely useful, however implementing a framework round these drivers is difficult. It would work on common, however not constantly.
And the extra filters round investor threat sentiment metrics, the decrease the precise allocation to the issue and the extra usually money is held. Buyers don’t wish to be out of the market, particularly when the worth issue is performing effectively.
It’s nice to know the way to enhance the percentages of producing returns with low-cost shares, nevertheless it hardly makes worth investing straightforward.
