Small caps put on their best monthly showing since 2020. Bank of America says there's more upside ahead

Bank of America says small caps should continue to lead, following the Russell 2000's 12%+ April gain and best monthly performance since November 2020. The firm highlighted ETFs tied to profitability and estimate revisions, including SMLF, JSML, and AVDV, as ways to express the theme beyond the Russell 2000. The message is supportive for small-cap positioning, but it is primarily strategic commentary rather than a near-term market catalyst.

Analysis

The market is rewarding a narrower, more selective version of the small-cap trade: profitable balance sheets, positive estimate momentum, and exposure to capex beneficiaries rather than generic beta. That matters because the next leg is likely to be driven less by multiple expansion and more by earnings credibility; in that regime, indexes with heavy unprofitable weightings can lag even if the broad complex stays bid.

The second-order winner is the capex ecosystem behind AI/data-center buildout. Names tied to power delivery, electrical infrastructure, and networking can keep outperforming even if the small-cap factor cools, because their demand is secular and their customer concentration is moving up the quality curve; that should also help suppliers with pricing power and hurt lower-quality industrials that are only riding the liquidity wave.

The international value sleeve is more interesting as a correlation diversifier than a pure return-chasing vehicle. If the U.S. growth complex stalls or rates stay sticky, non-U.S. small-cap value can still work on valuation compression and mean reversion, but it will likely underperform in sharp risk-off episodes because liquidity is thinner and FX can dominate fundamentals. The key risk to the thesis is that this becomes a crowded defensive-growth rotation inside small caps; if revisions breadth rolls over for even 4-6 weeks, the market will rapidly penalize the same factor exposures it just rewarded.

The contrarian read is that the market may be overpaying for ‘quality small caps’ just as the easy part of the earnings recovery is already in the tape. If macro data disappoints or manufacturing improves only superficially, the rally could narrow further to a handful of infrastructure and power names, leaving the broader basket vulnerable to a 5-8% giveback even while the headline index holds up.

Key Decisions for Investors

• Go long SMLF versus IWM for the next 1-3 months: favor the profitable/factor-screened basket over the broad index while revisions remain positive; target 4-6% relative outperformance, stop if breadth deteriorates or IWM reclaims leadership.
• Add JSML on pullbacks for a 6-12 week trade, but size it as a satellite position: momentum in estimate revisions can persist longer than price-only breakouts, with upside skew if earnings season confirms guidance raises; trim aggressively if revisions breadth flattens.
• Pair long NVT / short a basket of lower-quality industrial small caps: the best setup is persistent AI/power infrastructure spend versus cyclical names that need a manufacturing rebound to justify multiples.
• Use AVDV as a diversifier, not a core bet: initiate only if U.S. small-cap leadership becomes crowded or valuation spreads re-widen; expect lower beta, lower correlation, and slower upside than domestic growth pockets.
• Avoid chasing BE outright after the parabolic move; instead, consider call spreads or wait for a 15-20% reset. The name has the strongest upside torque, but the risk/reward is now more dependent on flawless execution and continued data-center demand.
