Introduction
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 traders or lecturers on what’s driving both technique.
That’s not on account of a scarcity of analysis. Hundreds of papers have scrutinized fairness components 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 technique’s returns is crystal clear, fund managers will likely be out of labor when the atmosphere for his or her funding type turns unfavorable. They’re higher off remaining publicly obscure about efficiency drivers, as that helps to retain their belongings underneath administration (AUM).
A second difficulty is that efficiency drivers are by no means crystal clear. Finance is just not a tough science with immutable, gravity-like legal guidelines. Markets change repeatedly and historic efficiency and traits will not be completely replicable. So in relation to efficiency drivers, finance practitioners should dwell 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 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 could be temporal or structural: an overleveraged stability sheet or being a part of an business in decline, for instance. Both method, traders will discover these shares uncomfortable to carry for the reason that related information move and dealer rankings will are usually downbeat.
Which means traders are more than likely to danger shopping for questionable corporations after they’re extra assured concerning the economic system and the inventory markets. When the economic system is heading into recession, traders are inclined to desire corporations with high quality or development traits. Put one other method: Danger sentiment is the first efficiency driver of the worth issue.
There are a lot of variables with which to measure danger 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 worth issue out of the most cost effective 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.
Many of the worth issue’s optimistic returns from 1926 to 2020 may be attributed to lowering volatility. This relationship is just not excellent, nonetheless: Between 1931 and 1943, worth issue returns fell amid rising volatility. However from then on, returns had been persistently adverse when volatility was on the upswing.

These outcomes present some help 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 generally happens because the economic system deteriorates. Traders desire lower-risk investments throughout such durations and thus are inclined 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, but it surely 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 all the worth issue’s optimistic returns happen amid durations of optimistic skewness, when no extreme crashes have not too long ago occurred. Traders really feel secure and are extra prepared to wager on troubled corporations.

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 Danger Administration
Primarily based on these findings, traders would possibly take into account making use of these metrics to time the worth issue. We suggest approaching this from a danger 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 adverse.
Our multi-metric danger 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 eventualities during 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 bounds of our yield curve knowledge, three optimistic alerts representing a market atmosphere 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 no less than one optimistic sign generated returns akin to that of the buy-and-hold worth issue. Nevertheless, with two and even three alerts, returns had been rather more per considerably lowered drawdowns. The general returns had been decrease than these of the worth issue on account of each excessive money allocations and the restricted yield curve knowledge.
Multi-Metric Danger Administration Framework for the Worth Issue
We additionally evaluated the efficiency of the worth issue when the alerts had been adverse. 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 alerts, alternatively, yielded constant losses, which represents a market atmosphere of accelerating volatility, adverse market skewness, and a downward sloping yield curve.

All advised, this evaluation is much from excellent. Now we have not totally 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 widespread risk-measurement variables and publicly obtainable knowledge, made few assumptions, and utilized our methodology to greater than 90 years of economic historical past. This offers some consolation within the significance of those outcomes.
One clearly defective assumption is our same-day software of the buying and selling alerts. That is unattainable to implement since modifications within the variables and inventory markets happen concurrently.
Identical-Day vs. Subsequent-Day Buying and selling: CAGRs, 1926–2020
To make the alerts extra sensible, we analyzed what would happen if the trades had been carried out the subsequent day. That led to important reductions within the CAGRs for the frameworks requiring one or two optimistic alerts, however not for 3 optimistic alerts.
Additional Ideas
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 typically money is held. Traders don’t wish to be out of the market, particularly when the worth issue is performing nicely.
It’s nice to know the way to enhance the percentages of producing returns with low-cost shares, but it surely hardly makes worth investing straightforward.
