Small—Cap Stocks Got a Payrolls Boost — But CPI Is the Real Test

A surprise contraction in US payrolls has given the stock market a break from worrying about a near-term interest-rate increase.

Whether it gives small-cap stocks a durable reprieve depends on Wednesday’s inflation report.

Nonfarm payrolls fell by 23,000 in July, against forecasts for an 83,000 gain.

The shock drove the two-year Treasury yield to a three-week low and led futures traders to abandon bets for a September Federal Reserve rate increase.

Small caps rallied further, and iShares Russell 2000 ETF (NYSE: IWM ) is up around 22% year-to-date, outperforming both State Street SPDR S&P 500 (NYSE: SPY ) and Invesco QQQ Trust (NASDAQ: QQQ ), which rose by 13% and about 17% respectively.

The Russell 2000’s Structural Trap Small caps are structurally tied to interest rates.

According to The Kobeissi letter, Russell 2000 companies devote roughly 31% of earnings before interest, taxes, depreciation and amortization to interest expense.

That number is an order of magnitude higher than the S&P 500’s 7%. "A Fed tightening cycle would pose a bigger risk to small-caps than large-caps," Goldman Sachs analyst Ben Snider recently wrote.

Smaller companies refinance more frequently and depend more on short-term credit, whereas megacap technology firms have cash cushions and long-dated fixed-rate debt.

Despite strong outperformance, Goldman says that small caps might be running ahead of its fundamentals.

The index became less exposed to an important source of earlier momentum after June’s reconstitution cut the weighting of AI-infrastructure companies to 7% from 15%.

Meanwhile, unprofitable businesses account for 29% of constituents and 23% of market capitalization. "While analyst estimates point to strong EPS growth, roughly a quarter of the Russell 2000 is unprofitable," Snider added.

RBC Reiterates Tight Labor Market Meanwhile, RBC has cautioned against reading the payroll number as evidence of widespread layoffs.

Participation among workers aged 25 to 54 rose to 83.4% from 83.3%, while participation fell among people under 24 and those 55 or older.

The unemployment rate declined to 4.1% as the labor force contracted.

The pattern is "more consistent with retirements than layoffs," RBC analysts noted, stating that average weekly hours in private industries were broadly stable.

Firms usually reduce hours before cutting staff, they argued.

Thus, the new data "does not mark a significant departure from our base case narrative" of a tight labor market, analysts concluded, believing that the payroll drop doesn’t yet signal the recessionary downturn that would cripple the domestic-focused small caps.

That argument leaves Wednesday’s CPI for the next test of the soft-landing narrative.

CPI as the Next Big Test According to CNBC, economists surveyed by Dow Jones expect July headline CPI to slow to 3.4% year-on-year from 3.5% in June, and core CPI to ease to 2.5% from 2.6%.

Kalshi traders assign less than a 55% probability to headline inflation exceeding 3.3%, and only 15% odds of a reading above 3.4%.

A benign result would reinforce the case for a Fed hold ahead of September.

But it won’t, by itself, resolve small caps’ dilemma.

Those firms are holding onto the financing Goldilocks zone — where borrowing costs are low enough to survive without stoking inflation, yet not high enough to trigger defaults while simultaneously eroding the overwhelmingly domestic revenue base.

Wednesday’s print will show whether that safety is within reach.
