Is the Mega-Cap Era Over? The Case for a Small-Cap Rotation

Skyscrapers

Bigger isn’t always better—especially when market leadership starts to crack. In Q1, the so-called Mag 7 mega-cap stocks posted their worst underperformance on record, dropping nearly 16%. Investors quickly rebranded them the Lag 7, signaling that the era of large-cap dominance may be running out of steam.

While near-term performance in small-cap strategies is mixed, the long-term fundamentals tell a different story. According to research by Professor Kenneth French, over the last 50 years, small-cap stocks—those in the bottom two-thirds of the market by size—outperformed their large-cap counterparts by 300 basis points annually. The recent stretch of mega-cap dominance has flipped that trend, with small caps underperforming by over 500 basis points per year. But today, U.S. small caps trade at a 24% discount to large caps—levels historically tied to major reversals, like those seen from 1974–1981 and 1998–2018.

In other words: mean reversion is setting the stage for small caps to take the lead.

Beyond valuation, small caps bring something the market desperately needs right now — diversification. In an environment dominated by a handful of names, smaller companies offer access to future leaders, not yesterday’s monopolies. As Jim Chanos said, “Monopoly profits are hard to maintain.” Small companies aren’t facing that wall. They’re better positioned to benefit from AI deployment, emerging market consumption, regulatory easing and global stimulus.

They’re also acquisition targets in slower-growth environments and have more room to expand margins.

International small caps are even more compelling. Under-owned, under-analyzed, and fundamentally attractive, they’re trading at just 10x earnings, at book value, and yielding over 4%. While U.S. small caps are still lagging, their global counterparts in China, Europe and key emerging markets are already outperforming.
