Ted Theodore first wrote about worth versus momentum shares method again in 1984, however nearly 40 years later, there nonetheless is not any actual consensus amongst buyers or teachers on what’s driving both technique.
That’s not as a result 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 will likely be out of labor when the surroundings 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 problem is that efficiency drivers are by no means crystal clear. Finance just isn’t a tough science with immutable, gravity-like legal guidelines. Markets change constantly and historic efficiency and tendencies are usually not completely replicable. So in the case of 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 needs 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 dedication?
What Is Driving the Worth Issue?
The worth issue generates optimistic returns when low-cost shares outperform costly ones. So when does that occur?
Low-cost corporations are typically troubled corporations. In any other case, they wouldn’t commerce at low valuations. Their points may be temporal or structural: an overleveraged steadiness sheet or being a part of an trade in decline, for instance. Both method, buyers will discover these shares uncomfortable to carry for the reason that related information circulate and dealer rankings will are typically downbeat.
Which means buyers are almost certainly to danger shopping for questionable corporations once they’re extra assured in regards to the economic system and the inventory markets. When the economic system is heading into recession, buyers are likely to favor corporations with high quality or development traits. Put one other method: Threat sentiment is the first efficiency driver of the worth issue.
There are numerous variables with which to measure danger 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 price issue out of the most affordable and costliest 10% of shares within the US inventory market as measured by price-to-book ratios utilizing knowledge from the Kenneth R. French Knowledge Library. We then calculated the Z-score of inventory market volatility utilizing a three-month lookback.
Many of the worth issue’s optimistic returns from 1926 to 2020 may be attributed to reducing volatility. This relationship just isn’t good, nonetheless: Between 1931 and 1943, worth issue returns fell amid rising volatility. However from then on, returns had been persistently unfavourable when volatility was on the upswing.

These outcomes present some assist for the premise that danger sentiment is the important thing efficiency driver of the worth issue: Inventory market volatility tends to rise when financial volatility will increase, which usually happens because the economic 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, however 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 optimistic returns happen amid durations of optimistic skewness, when no extreme crashes have lately occurred. Buyers really feel protected and are extra keen to wager 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 info 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 optimistic returns of the worth issue occurred when the yield curve was upward sloping, or when financial circumstances had been extra bullish.

Combining Metrics for Issue Threat Administration
Primarily based on these findings, buyers would possibly take into account making use of these metrics to time the worth issue. We advocate approaching this from a danger moderately than a return perspective. That’s, we advise specializing in avoiding important drawdowns when the market surroundings for proudly owning low-cost shares is extra unfavourable.
Our multi-metric danger administration framework solely allotted to the worth issue when a mix of inventory market volatility, market skewness, and yield curve had been favorable. Particularly, we modeled three situations through which one, two, or three alerts are required for an element allocation. With out the required alerts, zero-interest money was held as an alternative.
Given the boundaries of our yield curve knowledge, three optimistic alerts representing a market surroundings with falling market volatility, optimistic 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 optimistic sign generated returns akin to that of the buy-and-hold worth issue. Nonetheless, with two and even three alerts, returns had been way more in keeping with considerably diminished drawdowns. The general returns had been decrease than these of the worth issue as a result 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 alerts had 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 according to the buy-and-hold worth issue. Two or three alerts, however, yielded constant losses, which represents a market surroundings of accelerating volatility, unfavourable market skewness, and a downward sloping yield curve.
Multi-Metric Threat Administration Framework for the Worth Issue: Quick Indicators
All informed, this evaluation is much from good. We’ve not completely examined the framework for robustness. We may use price-to-earnings as an alternative of price-to-book for inventory choice, change the lookback durations, embrace transaction prices, apply the framework to worldwide markets and different asset courses, and so forth.
However we’ve got used frequent risk-measurement variables and publicly obtainable knowledge, made few assumptions, and utilized our methodology to greater than 90 years of economic historical past. This supplies some consolation within the significance of those outcomes.
One clearly defective assumption is our same-day utility of the buying and selling alerts. That is unattainable to implement since adjustments within the variables and inventory markets happen concurrently.
Similar-Day vs. Subsequent-Day Buying and selling: CAGRs, 1926–2020
To make the alerts extra life like, we analyzed what would happen if the trades had been performed the following day. That led to important reductions within the CAGRs for the frameworks requiring one or two optimistic alerts, however not for 3 optimistic alerts.
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 persistently.
And the extra filters round investor danger sentiment metrics, the decrease the precise allocation to the issue and the extra usually money is held. Buyers don’t prefer to be out of the market, particularly when the worth issue is performing nicely.
It’s nice to know learn how to enhance the chances of producing returns with low-cost shares, however it hardly makes worth investing straightforward.
