The iShares Russell 2000 ETF has surged to five new all-time highs in January, a feat not seen in over a decade. This streak has outpaced the S&P 500’s two record highs over the same period, underscoring a broadening market leadership. Trading volume for the small-cap benchmark has averaged 45 million shares daily, a 12 percent increase from last quarter, suggesting institutional conviction rather than speculative positioning.

Research from 22V indicates that U.S. productivity growth climbed 2.8 percent year-over-year in Q4, the fastest pace since 2018. This gain allows companies in the Russell 2000 to expand margins without stoking inflation, keeping financial conditions accommodative. Economists forecast 1.5 percent growth in nonfarm productivity for all of 2026, supporting sustained risk appetite in smaller stocks.

Regional bank stocks account for nearly 18 percent of the Russell 2000’s weight, and their earnings have risen 8 percent year-over-year through Q4. Loan-loss provisions fell by 22 percent from the prior quarter, reflecting improving credit quality. Analysts at 22V note the absence of fresh credit-health concerns in 85 bank earnings calls this season, reinforcing a lower recession risk priced into IWM.

Mentions of artificial intelligence on small-cap conference calls have jumped 42 percent year-to-date, as companies pivot from software pilots to embedding AI in physical products. Sectors such as semiconductors and capital goods—which together represent 14 percent of the Russell 2000—are expected to see capital expenditures rise by 10 percent in 2026. Strategists at 22V argue this shift could narrow the 220-basis-point EBITDA margin gap between small and large caps, setting the stage for another leg of outperformance.
