Small-Cap Stocks: Finding Hidden Gems in 2025

The Case for Small Caps

While everyone focuses on the Magnificent 7, small-cap stocks (companies with $300M-$2B market caps) often deliver the best returns. The Russell 2000 is starting to outperform as rate cuts favor smaller companies.

Why Small Caps Now?

Rate Cut Tailwind

Small-cap companies typically carry more debt than large caps. As rates fall:

Interest expenses decrease

Refinancing becomes cheaper

Profit margins expand

Valuations increase

Valuation Gap

The small-cap to large-cap valuation ratio is at historic lows:

Small caps trade at ~14x forward P/E

Large caps trade at ~21x forward P/E

This gap hasn't been this wide since 2000

M&A Activity

Lower rates and cash-rich large caps create an active M&A environment. Small caps are acquisition targets, often at significant premiums.
