Ted Theodore first wrote about worth versus momentum shares means again in 1984, however nearly 40 years later, there nonetheless isn’t any actual consensus amongst buyers or lecturers on what’s driving both technique.
That’s not because of 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 technique’s returns is crystal clear, fund managers shall 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 property below administration (AUM).
A second concern 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 traits usually are not 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 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 constructive 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 could be temporal or structural: an overleveraged stability sheet or being a part of an business in decline, for instance. Both means, buyers will discover these shares uncomfortable to carry because the related information stream and dealer rankings will are typically downbeat.
Meaning buyers are most definitely to danger 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 inclined to choose corporations with high quality or development traits. Put one other means: Danger sentiment is the first efficiency driver of the worth issue.
There are various variables with which to measure danger sentiment. We concentrate on 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 cost effective and most costly 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.
Many of the worth issue’s constructive returns from 1926 to 2020 might 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 had been persistently destructive 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 usually happens because the financial system deteriorates. Traders choose 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 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. Nearly the entire worth issue’s constructive returns happen amid intervals of constructive skewness, when no extreme crashes have lately occurred. Traders really feel protected 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 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 had been extra bullish.

Combining Metrics for Issue Danger Administration
Based mostly on these findings, buyers would possibly take into account making use of these metrics to time the worth issue. We suggest approaching this from a danger quite 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 destructive.
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 by 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 boundaries of our yield curve information, three constructive indicators representing a market atmosphere with falling market volatility, constructive market skewness, and an upward-sloping yield curve was solely potential 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 constructive sign generated returns similar to that of the buy-and-hold worth issue. Nevertheless, with two and even three indicators, returns had been rather more per considerably diminished drawdowns. The general returns had been decrease than these of the worth issue because of each excessive money allocations and the restricted yield curve information.
Multi-Metric Danger Administration Framework for the Worth Issue
We additionally evaluated the efficiency of the worth issue when the indicators had been destructive. This may very well be used to doubtlessly brief 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, then again, yielded constant losses, which represents a market atmosphere of accelerating volatility, destructive market skewness, and a downward sloping yield curve.
Multi-Metric Danger Administration Framework for the Worth Issue: Brief Indicators
All advised, this evaluation is way 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, embrace transaction prices, apply the framework to worldwide markets and different asset courses, and so forth.
However now we have used frequent risk-measurement variables and publicly out there information, 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 software of the buying and selling indicators. That is not possible 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 real looking, 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 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 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 prefer to be out of the market, particularly when the worth issue is performing nicely.
It’s nice to know enhance the percentages of producing returns with low-cost shares, however it hardly makes worth investing simple.
