# Small caps steal the spotlight as S&P 500 rally masks weak breadth

Investing.com - The U.S. equity rally has accelerated sharply in recent weeks, with the S&P 500 climbing roughly 7% since a bullish “true gap” signal emerged—already surpassing the historical median four-week gain of 6%.  
While momentum remains strong, market internals suggest a more complex and uneven picture beneath the surface, BTIG said in its report.

Despite the index pushing to new highs in four of the past six sessions, market breadth has been unusually narrow. On three of those four days, declining stocks outnumbered advancers, and fewer than 60% of S&P 500 components are trading above their 200-day moving average—even after a rapid 14% surge in just 23 days. Historically, such conditions have been rare, with similar patterns last seen during the late stages of the dot-com era.  
Analysts notes that previous rallies of similar magnitude—such as in 1991 and 1997—were supported by far stronger participation, with roughly 80% of stocks above their long-term averages. In contrast, the late-1999 and early-2000 rallies showed weak breadth and ultimately marked a major market top. Today’s reading of 58% sits in between, raising caution but not yet signaling a definitive turning point.  
Further highlighting the uneven nature of the rally, the equal-weight version of the S&P 500 has yet to reach a new high, suggesting that gains are concentrated in a smaller group of large-cap stocks, analysts said.  
In contrast, smaller companies are showing stronger momentum. The Russell 2000 has reached new all-time highs, with improving breadth and relative strength versus the equal-weight S&P 500. The breakout in the small-cap-to-equal-weight ratio marks a shift after years of underperformance, signaling a potential broadening of leadership—just not within large caps.  
BTIG also said that outside the U.S., Chinese equities are quietly gaining traction. Funds such as the KraneShares SSE STAR Market 50 ETF (KSTR) and Xtrackers Harvest CSI 300 China A-Shares ETF (ASHR) are showing strong momentum, while the KraneShares CSI China Internet ETF (KWEB) appears to be bottoming, offering a more tactical opportunity.
