Is the IWM ETF Still a Buy After Its Recent Run-Up?

iShares Russell 2000 ETF (IWM) is up 18% year to date in 2026, nearly double the S&P 500’s 10.7% return, after small caps benefited from easing tariff pressure and expectations of Fed rate cuts. The Supreme Court struck down many 2025 tariffs, and 2026 earnings are forecast to rise 19% vs 13% for the S&P 500, with IWM trading at a 17x forward P/E vs 20x for the S&P 500.

Decision brief

The 30-second read

Med
01

Why it matters

The article argues the next leg for IWM depends on whether rate-cut expectations fade and whether Russell 2000 earnings growth (forecast 19% YoY) materializes versus inflation/geopolitical risks.

02

Market read

A rates-and-earnings read-through for small-cap positioning: tariff relief and earnings growth vs. higher-for-longer inflation risk.

03

What to watch

Earnings growth is forecast-based; the article doesn’t address margin pressure, refinancing risk, or how much of the tariff relief is already priced into IWM.

Relevance 7/10Novelty 4/10Timing: Post-run-up decision point for small-cap exposure

Background

Small caps were pressured in late 2025 by high rates and tariffs; the Supreme Court struck down many 2025 tariffs in early 2026, easing a major headwind.

Market effects

Supports a read-through that small-cap credit sensitivity and tariff exposure are key swing factors for the Russell 2000 complex.

Primarily US domestic small-cap earnings and financing conditions; limited direct regional spillover beyond US rates sensitivity.

Tariff/regulatory and global growth/inflation uncertainty can still transmit via US rates and corporate margins, affecting small-cap risk appetite.

Counterpoint

If inflation re-accelerates and the Fed shifts toward hikes, small caps’ debt sensitivity could overwhelm the earnings-growth optimism.

Bank of America raises Fed interest rate warning after October CPI surprise

Bank of America warns that October's higher-than-expected CPI (0.4% vs. 0.3% forecast) may force the Fed to raise rates more aggressively. Core CPI rose 0.3%, exceeding forecasts, with goods and services prices both contributing to inflation. BofA now expects a 0.25% rate hike in December, with a 0.50% hike becoming more likely. This could impact household budgets, stock markets, and corporate borrowing costs.
