Introduction
Ted Theodore first wrote about worth versus momentum shares approach again in 1984, however nearly 40 years later, there nonetheless is not any actual consensus amongst traders or lecturers on what’s driving both technique.
That’s not attributable to a scarcity of analysis. 1000’s 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 might be out of labor when the atmosphere for his or her funding fashion turns unfavorable. They’re higher off remaining publicly obscure about efficiency drivers, as that helps to retain their belongings below administration (AUM).
A second challenge 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 developments usually are not completely replicable. So in the case of efficiency drivers, finance practitioners should stay 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 must 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 usually 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 business in decline, for instance. Both approach, traders will discover these shares uncomfortable to carry because the related information move and dealer scores will are usually downbeat.
Which means traders are most definitely to threat shopping for questionable corporations once they’re extra assured concerning the economic system and the inventory markets. When the economic system is heading into recession, traders are likely to desire corporations with high quality or development traits. Put one other approach: Threat sentiment is the first efficiency driver of the worth issue.
There are numerous variables with which to measure threat sentiment. We give attention to 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 information from the Kenneth R. French Knowledge Library. We then calculated the Z-score of inventory market volatility utilizing a three-month lookback.
A lot of the worth issue’s optimistic returns from 1926 to 2020 could 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 damaging 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 usually happens because the economic system deteriorates. Traders desire 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 traders 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. Nearly the entire worth issue’s optimistic returns happen amid durations of optimistic skewness, when no extreme crashes have lately occurred. Traders really feel secure 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 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
Based mostly on these findings, traders would possibly take into account making use of these metrics to time the worth issue. We advocate approaching this from a threat fairly 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 damaging.
Our multi-metric threat administration framework solely allotted to the worth issue when a mixture of inventory market volatility, market skewness, and yield curve had been favorable. Particularly, we modeled three situations during which one, two, or three indicators are required for an element allocation. With out the required indicators, zero-interest money was held as an alternative.
Given the boundaries of our yield curve information, three optimistic indicators representing a market atmosphere with falling market volatility, optimistic market skewness, and an upward-sloping yield curve was solely attainable 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 at the very least one optimistic sign generated returns similar to that of the buy-and-hold worth issue. Nevertheless, with two and even three indicators, returns had been far more according to considerably lowered drawdowns. The general returns had been decrease than these of the worth issue attributable to each excessive money allocations and the restricted yield curve information.
Multi-Metric Threat Administration Framework for the Worth Issue
We additionally evaluated the efficiency of the worth issue when the indicators had been damaging. This could possibly 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 indicators, alternatively, yielded constant losses, which represents a market atmosphere of accelerating volatility, damaging market skewness, and a downward sloping yield curve.
Multi-Metric Threat Administration Framework for the Worth Issue: Brief Alerts
All informed, this evaluation is much from good. We now have not totally examined the framework for robustness. We might use price-to-earnings as an alternative 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 widespread risk-measurement variables and publicly obtainable information, made few assumptions, and utilized our technique to greater than 90 years of economic historical past. This gives some consolation within the significance of those outcomes.
One clearly defective assumption is our same-day software of the buying and selling indicators. That is unattainable 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 reasonable, we analyzed what would happen if the trades had been carried out the following day. That led to important reductions within the CAGRs for the frameworks requiring one or two optimistic indicators, however not for 3 optimistic indicators.
Additional Ideas
Understanding what drives worth issue efficiency is immensely useful, however implementing a framework round these drivers is difficult. It’ll work on common, however not persistently.
And the extra filters round investor threat sentiment metrics, the decrease the precise allocation to the issue and the extra typically money is held. Traders don’t prefer to be out of the market, particularly when the worth issue is performing properly.
It’s nice to know enhance the percentages of producing returns with low cost shares, nevertheless it hardly makes worth investing simple.
