Small-cap stocks are surging this month on strong momentum in the space. The Russell 2000 Index has jumped nearly 9% in July 2025 alone, outpacing the S&P 500 and Nasdaq Composite Indexes. 

While several ETFs are riding high on this momentum, we have highlighted five of those that are leading the space over the past month and offer diversified exposure across various sectors. These are Avantis U.S. Small Cap Equity ETF (AVSC Quick QuoteAVSC - Free Report) , Invesco S&P SmallCap Value with Momentum ETF (XSVM Quick QuoteXSVM - Free Report) , JPMorgan BetaBuilders U.S. Small Cap Equity ETF (BBSC Quick QuoteBBSC - Free Report) , iShares US Small Cap Value Factor ETF (SVAL Quick QuoteSVAL - Free Report) and WisdomTree U.S. SmallCap Fund (EES Quick QuoteEES - Free Report) .

Here’s a deep dive into the driving forces behind the current rally:

Renewed Fed Rate Cut Hopes

The recent bouts of economic data pointing to cooling inflation and a slowing job market have revived expectations of Fed rate cuts in the second half of 2025. Traders are now pricing in a possible rate cut as early as September. As the pint-sized companies have a higher debt burden (mostly at floating rates), lower rates lead to reduced borrowing costs, helping small businesses expand their operations easily and resulting in increased profitability.

Deep Valuation Discounts

Valuation has been another key driver. Small-cap stocks have been trading at a steep discount of nearly 55% to large caps by P/E. The forward P/E ratio for the Russell 2000 is currently near 14.2x, compared to 20.5x for the S&P 500. Investors, especially institutional funds, are beginning to rotate out of overbought mega-cap names and into under-owned areas of the market, including small-caps. This rotation has accelerated in July, leading to broad-based gains in small-cap ETFs.

Rebound in Sectors like Financials and Industrials

Small-cap companies in the financials, industrials, and consumer discretionary sectors, which together make up over 50% of the Russell 2000, are rebounding strongly. In particular, regional banks, which were battered in 2023–24 amid rate volatility and commercial real estate concerns, are staging a comeback as balance sheets stabilize and credit risks abate. Meanwhile, manufacturing and transportation stocks are gaining on improving supply chain dynamics and increased infrastructure-related spending (read: Big Banks Q2 Earnings Thrive: ETFs in Focus).

Increased M&A Activity

The M&A activity has picked up, especially around small and mid-sized firms in the healthcare, biotech, and tech services sectors. With cash-rich large-cap companies looking for growth through acquisitions, small-caps have become attractive targets due to their innovation and lean valuations. This speculative momentum is attracting active fund managers and hedge funds, adding further liquidity to the small-cap space.

Retail Investor and AI-Driven Strategies

Retail investors are returning to small-caps as the fear of recession fades and bullish sentiment builds. Trading volumes in popular small-cap names and ETFs have surged, fueled in part by social media chatter and AI-driven trading platforms. Quant-based hedge funds and AI-enhanced strategies are also contributing to the momentum, amplifying moves in thinly traded small-cap stocks (read: Small Business Optimism Grows: What's Ahead for ETFs?).
