Introduction
Ted Theodore first wrote about worth versus momentum shares means again in 1984, however nearly 40 years later, there nonetheless is not any actual consensus amongst traders or teachers on what’s driving both technique.
That’s not on account of a scarcity of analysis. Hundreds of papers have scrutinized fairness elements throughout markets and asset lessons, 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 type turns unfavorable. They’re higher off remaining publicly imprecise about efficiency drivers, as that helps to retain their property underneath administration (AUM).
A second situation is that efficiency drivers are by no means crystal clear. Finance shouldn’t be a tough science with immutable, gravity-like legal guidelines. Markets change repeatedly and historic efficiency and tendencies are usually not completely replicable. So in terms 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 needs to be implementable.
- It ought to maintain when examined throughout time, markets, and asset lessons.
So what’s the worth issue’s key efficiency driver? On what proof will we base that willpower?
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 business in decline, for instance. Both means, traders will discover these shares uncomfortable to carry for the reason that related information stream and dealer rankings will are typically downbeat.
Which means traders are probably to threat shopping for questionable corporations once they’re extra assured in regards to the financial system and the inventory markets. When the financial system is heading into recession, traders are inclined to favor corporations with high quality or development traits. Put one other means: Danger 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 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 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 will be attributed to lowering volatility. This relationship shouldn’t be excellent, nevertheless: Between 1931 and 1943, worth issue returns fell amid rising volatility. However from then on, returns have been constantly detrimental when volatility was on the upswing.

These outcomes present some assist 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 financial system deteriorates. Traders favor lower-risk investments throughout such intervals 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, however 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. Virtually all the worth issue’s optimistic returns happen amid intervals of optimistic skewness, when no extreme crashes have not too long ago occurred. Traders really feel protected and are extra keen to guess 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 situations have been extra bullish.

Combining Metrics for Issue Danger Administration
Primarily based on these findings, traders would possibly contemplate making use of these metrics to time the worth issue. We suggest approaching this from a threat quite 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 detrimental.
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 through which 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 bounds of our yield curve knowledge, three optimistic indicators representing a market surroundings 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 no less than one optimistic sign generated returns corresponding to that of the buy-and-hold worth issue. Nevertheless, with two and even three indicators, returns have been rather more in line with considerably diminished drawdowns. The general returns have 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 indicators have been detrimental. This could possibly be used to probably brief the issue by shopping for costly and promoting low-cost shares.
A one-signal requirement generated efficiency in step with the buy-and-hold worth issue. Two or three indicators, however, yielded constant losses, which represents a market surroundings of accelerating volatility, detrimental market skewness, and a downward sloping yield curve.

All instructed, this evaluation is much from excellent. We have now not totally examined the framework for robustness. We may use price-to-earnings as a substitute of price-to-book for inventory choice, change the lookback intervals, embody transaction prices, apply the framework to worldwide markets and different asset lessons, and so forth.
However now we have used frequent risk-measurement variables and publicly out there knowledge, made few assumptions, and utilized our technique to greater than 90 years of monetary 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 indicators. That is unimaginable to implement since modifications within the variables and inventory markets happen concurrently.
Similar-Day vs. Subsequent-Day Buying and selling: CAGRs, 1926–2020
To make the indicators extra reasonable, we analyzed what would happen if the trades have been performed the subsequent 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’s going to 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 typically money is held. Traders don’t wish to be out of the market, particularly when the worth issue is performing effectively.
It’s nice to know the right way to enhance the chances of producing returns with low-cost shares, however it hardly makes worth investing simple.
