Model regimes represent considered one of traders’ largest threat components, second solely to general fairness publicity. After 15 years of progress fashion dominance, the return of intra-market volatility has prompted renewed curiosity in fashion framework and cyclical rotations. By reacquainting ourselves with the dynamics of fashion cycles, we are able to higher perceive how these portfolio constructing blocks form our monetary futures.
On this evaluation, I’ll reveal that fashion returns are the market’s veritable gulf stream, and traders mustn’t ignore their highly effective currents. I’ll deal with three primary but basic questions:
1. What’s the typical length of progress and worth fashion regimes?
2. How impactful are oscillations between progress and worth?
3. What are the mechanics of fashion transition?
With its three easy, but highly effective inputs, I imagine the Russell Model methodology can unravel among the market’s most resonating behaviors.
What’s the typical length of progress and worth fashion regimes?
With the sharp 2022 rotation to worth shares recent within the reminiscence, traders wish to know whether or not rotations are transitory actions or sturdy market developments. To offer context and steering, I measured the ratio of the whole returns of the Russell 1000 Progress and Worth Indexes from December 1978, rebased to 100 as an preliminary worth.
This system permits us to look at distinct intervals of outperformance by both progress or worth with out distraction from the runaway compounding of fairness returns. The strategy is time-agnostic: cross-period comparisons, reminiscent of between the Eighties and the 2010s, will be made on a roughly equal foundation.

By connecting peaks and troughs within the chart above, 10 discrete intervals of fashion efficiency will be readily recognized. Upward surges point out the outperformance of progress, whereas downward developments reveal a rotation towards worth. What’s fascinating is that such clear cyclical patterns emerge, despite the fact that month-over-month fashion returns proceed in the identical path solely 51.9% of the time — a price indistinguishable from a coin toss!
Some mannequin judgements are mandatory in assigning fashion regimes. For instance, regimes 5 and 6 are separated as a substitute of counting one mixed progress regime through the Nineties, as a result of these two phases are extra distinct from one another than progress and worth are on common. However such discretionary calls, this framework presents an evidence-based strategy to breaking down the wave perform of fashion returns.
4 completely different measures of pattern measurement and depth are depicted. PP Change denotes the share level change within the ratio of Russell 1000 Progress and Worth Index whole returns throughout every regime. Column PP/Month is the speed of change within the earlier worth and is the typical slope for every regime. Regime 10 remains to be in section and doesn’t signify a accomplished regime. Supply: FTSE Russell, February 2024.
The common length of fashion regimes is 64 months, however there may be much more nuance than this headline quantity would recommend. First, there’s a excessive dispersion in regime size, starting from 13 months on the quick finish (regime 9) to 184 months on the lengthy finish (regime eight), a variety of a couple of order of magnitude.
In reality, the 15-year Nice Progress Regime (GGR, regime eight), which lasted from July 2006 to November 2021, is a real outlier that skews the general outcomes. Notably, regime eight lies 2.3 commonplace deviations out from the imply regime size (4.6 if excluded from pattern).
We arrive at a extra consultant understanding of fashion regime size by isolating the influence of the 15-year GGR. The general common cycle size decreases to 46 months, and the typical length of progress regimes is sort of halved to 33 months. Therefore, we are able to conclude that fashion regimes will not be taste of the month phenomena, however reasonably they’re usually multi-year developments. Moreover, when excluding the GGR, worth regimes are likely to persist for twice so long as their progress brethren.
How impactful are oscillations between progress and worth?
After 44 years, the annualized returns of those antithetical methods differed by solely 42 foundation factors, and progress and worth achieved return parity as not too long ago as March 14, 2023. If each fashion methodologies take traders to roughly the identical vacation spot, simply how vital are fashion developments? Are they mere ripples on the general floor of fairness returns?
It’s extra acceptable to speak of highly effective waves: the oscillations between progress and worth carry super influence. Calculating the charges of change within the ratio of progress and worth whole returns reveals that fashion developments progress on common at a price of 1.15 share factors monthly (pp/m).
For context, this fashion pattern velocity is 44% larger than the anticipated month-to-month returns for fairness markets, whereas progressing at solely 55% of the latter’s volatility. This evaluation demonstrates that fashion developments are each extra forceful and extra constant than these of the underlying fairness market. In sum, these gyrations equate to $600 billion in shareholder wealth being reallocated between progress and worth every month.
Whereas the typical fashion regime sees a 40.9 share level swing within the ratio of progress/worth whole return, there may be nice variance within the pacing of fashion returns on the regime stage. Traditionally, worth regimes have progressed 26% extra shortly than their progress counterparts, owing to fast worth reversions after progress developments culminate.
Excluding the mid-Nineties fashion neutrality of regime 5 with its development price of solely 0.12pp/m, the GGR was the least dynamic fashion pattern, progressing at solely 0.39 pp/m. Examine this gradual pacing with the subsequent worth cycle (regime 9 within the desk) which was probably the most aggressive on report, surging at a unfavorable 2.52pp/m clip. This reversal of fashion path after a 15-year regular state, in addition to a sixfold intensification of fashion, contributed to the market whiplash sensation skilled by many fairness traders in 2022.
Completely timing these 10 Russell fashion regimes would have meant a close to sevenfold enhance to base index returns since 1979, catapulting investor positive aspects from a 162 occasions enhance to a staggering 1,247 a number of of preliminary principal. Even when traders had missed these transitions by a 3-month lag, they may nonetheless have captured a fourfold enhance to the Russell 1000 Index return, appreciating 653 occasions. In contrast, a supremely unfortunate investor constantly out of section with the prevailing fashion pattern would have achieved solely 10.5% of the benchmark’s positive aspects. Merely put, fashion allocations matter — however how can traders revenue from these key moments in fashion transition?
What are the mechanics of fashion transition?
The first distinction between the growth-to-value and the value-to-growth transitions lies of their dynamism. Rotations into worth are constantly much more dramatic occasions, with 5.57 occasions the market fashion displacement on common. This worth is calculated by measuring the whole change within the ratio of progress and worth whole returns within the three months previous and following every fashion maxima or minima. In essence, it captures how a lot floor the market coated from a mode perspective through the transition.
The unambiguous conclusion is that not like attenuated, U-shaped shifts into progress, rotations into worth are pretty violent market occasions. Whereas traders have time and alternative to evaluate threat and reposition as progress returns to favor, they haven’t any such luxurious with reversions to worth.

Blue signifies progress regimes, rose worth regimes. Supply: FTSE Russell, February 2023.
Why is there such a disparity in rotation depth? It stems from a basic attribute of all progress regimes — they spike in returns because the fashion pattern culminates. No progress cycle has ever ended with out this ultimate bout of exuberance. Certainly, the final 20% of a progress pattern captures 50.8% of the fashion returns. The chance lovers amongst us can rejoice, as in these progress climaxes, fashion returns accrue at 6.23 occasions the speed recorded through the the rest of the regime.
Progress and worth regimes are segmented into one fifth buckets by time development, illustrating their seize price of whole regime fashion returns. Supply: FTSE Russell, February 2024.
Maybe as hanging because the regularity and predictability of those progress flares, is the symmetry of the following progress collapse and worth resurgence. Simply as progress regimes see their fashion returns back-loaded within the cycle, worth regimes are front-loaded to the identical proportion of fifty.8%.
Not solely does this terminal progress spike create a sample that reverberates by means of the historical past of fashion cycles, but it surely additionally suggests the lead right into a market rotation is predictive of the depth of the departure into the subsequent cycle.
Furthermore, we are able to use the lens of volatility to corroborate this U- versus V-shaped framework of progress and worth fashion transitions. An evaluation of the six months encapsulating every fashion rotation finds that shifts to progress happen with market volatility and magnificence volatility 1.4 factors beneath common, whereas transitions to worth see these volatility measures will increase by 0.9 and three.6 factors, respectively.
For added context, these figures signify that progress transitions fall on the 48th percentile for fashion pattern volatility, whereas shifts to worth attain the 86th percentile. In different phrases, shifts from worth to progress and shifts from progress to worth are two completely different animals solely.
Inexperienced factors connotate progress regimes, purple worth cycles. Knowledge observations primarily based on averaged volatilities through the 7 months encompassing every transition level (3 months previous to, the month of transition and three months trailing).

Model to Your Benefit
Model cycles are sturdy, multi-year developments that symbolize a robust undertow beneath the surface-level returns of fairness markets. Given the significance of fashion returns and their related volatility patterns, probably the most risk-efficient approach to profit from fashion transition is to aggressively allocate to worth after a corresponding regime change.
Not solely do these fashion transitions present clear market indicators after they happen, however worth fashion returns expertise an early cycle focus, and reduce in depth as they progress. Furthermore, the eventual rotation again to progress has traditionally been a gradual affair, diminishing the investor’s threat to over or undershooting the fashion transition.
To additional generational understanding of progress and magnificence methodologies, in addition to their sensible functions, I’ve written three papers in a collection of 4, out there on FTSE Russell’s analysis library.
