Bank of America has altered its stance on small- and mid-cap equities heading into the second half of 2026, now preferring mid-cap shares over small-cap stocks after the Russell 2000 climbed 21% in the first half - the strongest gain among major size indexes.
In its note, analyst Jill Carey Hall said the firm continues to "still prefer SMID over mega," but that the argument for small-cap outperformance diminished after the rally. BofA highlighted the growing probability of additional Federal Reserve rate increases as a key differentiator between the two segments.
The bank quantified the sensitivity of small-cap earnings to rate moves, estimating that "every 25 basis points hike is a roughly 2% hit to Russell 2000 operating earnings." BofA's economists now expect a total of 75 basis points of tightening this year, delivered as three 25 basis-point increases in September, October and December, and project the Fed to remain on hold in 2027. Under that path, the bank warned that small caps carry the greatest refinancing risk.
Valuation dynamics also inform BofA's recommendation. Mid-cap valuations have moved close to those of small caps, and both groups are expected to see comparable earnings acceleration in the second half. Yet the bank observed that mid-caps exhibit the "strongest guidance and revision trends," and that differential pushed mid-caps ahead in its preference.
Style positioning is part of the bank's guidance as well. BofA expressed a preference for Value over Growth, noting that Value tends to lead during periods of earnings recovery and currently trades cheaply relative to Growth within both small- and mid-cap universes. Within the small-cap space, the bank advised tilting toward Quality, citing that low-quality outperformance recently reached a three standard deviation extreme "close to February 2000 levels."
Finally, BofA flagged leveraged companies with refinancing exposure as names to avoid given the expected rate path and associated refinancing pressures. Investors are being urged to weigh balance-sheet strength and guidance momentum when positioning across SMID (small and mid-cap) equities for the back half of the year.
