Small Caps Need Falling Wages

There's a signal hiding in the jobs report that most investors miss. It's not the headline number—it's the direction of wage growth.

Everyone watches the unemployment rate. The sophisticated crowd watches job openings. Almost nobody watches what happens to small caps when wage growth changes direction. That's a mistake, because the signal is remarkably consistent—and it's flashing right now.

Here's what caught my attention: wage growth has been quietly decelerating all year. In February, average hourly earnings were climbing at 4.18% year-over-year. By December, that had slipped to 3.55%. A 63 basis point decline doesn't make headlines. But it shows up in returns.

The question isn't whether wages are high or low. It's whether they're accelerating or decelerating. When I measured the 6-month change in the year-over-year rate, the current reading came in at -0.40. That puts us firmly in "decelerating" territory.

So what? Here's what.

The pattern nobody talks about

I went back to 1987 and classified every month into three buckets based on whether wage growth was accelerating, stable, or decelerating. Then I measured how small caps (Russell 2000) performed versus large caps (S&P 500) in each regime.

The results weren't subtle.

Wage Regime Small Cap Large Cap Spread Months
Decelerating +1.72%/mo +0.81%/mo +0.91pp 187
Accelerating +0.76%/mo +0.63%/mo +0.13pp 201
Stable +0.34%/mo +0.69%/mo -0.34pp 338

When wages decelerate, small caps outperform by nearly a full percentage point per month. When wages are stable, large caps actually win. Acceleration? Barely matters.

+0.91pp per month Small cap outperformance during wage deceleration regimes (187 months of data)

Why would this be? Small companies tend to be more labor-intensive than large ones. They have less pricing power and thinner margins. When wage pressures ease, their margins expand faster. Large caps—with their global supply chains and automation—don't get the same relief.

"It's not about whether wages are high or low. It's about whether the pressure is building or releasing."

But there's a catch

The relationship isn't constant. It depends on what else is happening in the economy—specifically, inflation.

When I split the data by both wage acceleration and CPI level, a clearer picture emerged:

Wages Inflation Small Cap Edge Months
Decelerating Low (<3%) +1.25pp/mo 71
Decelerating High (>3%) +0.42pp/mo 115
Other Low -0.16pp/mo 258
Other High -0.55pp/mo 281

The sweet spot is wage deceleration combined with low inflation. Small caps outperform by 1.25 percentage points per month—15 points annualized. That's not noise. That's alpha.

Current CPI? 2.65%. We're in the favorable quadrant.

It's already showing up

This isn't just historical pattern-matching. Look at what's happened year-to-date:

Index YTD 2025 Last 3 Months
Russell 2000 +18.54% +5.82%
S&P 500 +15.82% +0.92%
Small Cap Lead +2.72pp +4.90pp

Small caps have outperformed by nearly 5 percentage points over the past three months. The regime signal and the price action are telling the same story.

The setup Wage growth is decelerating. Inflation is below 3%. Small caps are already outperforming. The historical pattern and current price action are aligned.

Names worth watching

If you want exposure to quality small caps, here's what a screen for profitable companies with reasonable valuations and positive momentum looks like right now:

Symbol Company Mkt Cap P/E Margin 3M Return
MATX Matson (Shipping) $4.6B 10.7 12.7% +53.6%
ANF Abercrombie & Fitch $4.9B 9.3 10.1% +51.1%
CGAU Centerra Gold $3.3B 10.1 26.4% +49.8%
KEX Kirby Corp (Marine) $7.0B 22.9 9.2% +46.8%
GTX Garrett Motion $3.7B 11.3 9.2% +43.4%
WHD Cactus (Energy Svcs) $3.7B 21.2 15.9% +42.0%

These span shipping, retail, mining, marine transport, auto parts, and energy services. All profitable, all with P/E under 25, all with strong recent momentum. The common thread: labor-intensive businesses that benefit when wage pressure eases.

What would change the thesis

Two things to watch. First, wage acceleration. If monthly earnings growth picks back up—say, the year-over-year rate climbs back above 4%—the small cap edge narrows. The February jobs report will be the next data point.

Second, inflation. If CPI rises above 3%, the edge shrinks from +1.25pp to +0.42pp per month. Still positive, but less compelling. Watch the January CPI print.

For now, the signal is clear. Wages are decelerating, inflation is low, and small caps are running. Sometimes the market actually follows the playbook.
